THOUGHTS FROM THE EDITOR

WELCOME to your magazine PROFESSIONALISM l Indeed what is it? What does it mean for Dental Technicians? I ask this because until recently we in dentistry thought of the profession as the clinician and the rest as workers to the profession. Registration and the law change as a consequence of the breast implant scandal, now requires all of us to be registered, as we are legally required, to continue working as a Dental Technician.

The dental profession has now expanded to include all those who have a role in treating patients and professional courtesy should encompass all of us. At a recent meeting of representatives from various bodies speaking on behalf of dental professions it became clear that the onus on all of us to behave professionally begins with our own behaviour. So what does that mean?

To start with it means you take your commitment to the patient seriously and do the very best you can to provide exactly what their dentist prescribed.

Any shortcomings should be discussed with the clinician, whether its poor information, poor impression or poor bite record. If you have reservations around the particular techniques used by the clinician you should make an occasion by phone or visit to confer. It may be the client is not interested, none the less it is totally unprofessional to ignore it or sit and complain to others without trying to change the situation. You must recognise that now you are as responsible as the clinical team for the quality and suitability of the restoration. Telling all and sundry that he /she are useless at taking an impression or bite record or indeed a shade, without trying to change it, makes you as culpable, because you are not fulfilling our duty to the patient. As a professional you are equally guilty for the poor quality of restoration if you decide just to take the money and say nothing.

So professionalism is accepting the responsibilities for correct treatment as a required duty, which is owed to the patient.

So instead of just blaming others you must actively encourage everything, which can

4

assist the outcome. Good communication is one of the most important commitments you should make. As a technical expert professional you are required to know and to ensure that knowledge is not ignored. Your knowledge and ability has given you the responsibility to ensure the patients’ welfare is paramount. Ignoring the shortcomings of the clinical operator is reneging on your commitment to the patient.

Commenting on the quality of work of other technicians and laboratories in a negative way, with those not involved, is also against your professional responsibility.

So being professional as a technician means you are responsible, (as you are in law), for shortcomings which were allowed, with your knowledge by choosing, for whatever reasons, to look the other way.

It may also be considered unprofessional to castigate the failings of your professional colleague, i.e. the dentist, to other professionals or associates. You are very much part of that inner sanctum of professionals, responsible for the health and well being of the patient.

I only mention this as I don't think too many of you have realised that is not just the “bloody GDC and the cost or the CPD

www.dentaltechnician.org.uk

requirements” but in fact a complete new way of working and attitude for many of you. Whereas in the past, any thought the dentist was getting all the qudos, plus the large share of the reward for your lovely work and all your knowledge was a norm, today the situation is that it is of course a team effort and all members of the team are equally responsible to the patient. Your share of the spoils should be a negotiable figure between you and the dentist but as a committed member of the team with the extra responsibilities of registration perhaps you should be looking to increase the reward. Being professional means behaving professionally and requires a public demonstration of your belief in the ability of your co team members. Yes it will also mean a potential change for the average dentist as he becomes more and more reliant on those around day to day.

A learning curve for all of us. Hopefully the patients will become more informed and more aware of what is suppose to be happening as they go through the treatment and perhaps have a bit more say in the final outcome. The profession can feel confident they are providing exactly what it is required to meet their and professional colleagues commitments to the patient.

INSIGHT

FLUORIDATION TO STOP THE ROT!

T

he HPV campaign has had a great result. As of next year, probably August, HPV vaccine will be available for teenage boys as well as girls. Further the age group will be broadened as a boost to the start.

Australia started this across the sexes inoculation, before us. The primary target of the inoculation is cervical cancer. Australian research indicates a realistic prospect of virtual elimination of cervical cancer in a few years.

Therefore we should expect a similar result here along with a massive reduction in head and neck cancer in the decades to follow. Of course the success will be dependent on the up take of the inoculations. Parents need to be pushed. Some do not care or ignore advice.

Worse still some are against inoculations despite sound medical advice.

This brings me to a longstanding dental caries prevention method where the UK lags way behind many other Western nations. That is water fluoridation. Again Australia leads the way. About 70% of Australian water supplies are fluoridated. In England it is about 10%.

Every time I mention fluoridation in a public forum the looney fringe rise up. My favourite was a lady who wrote every time in shaky writing in purple ink on blue paper from Peru! Every medical malady known to man, plus a few more seemed to be blamed on fluoridated water. These flow through the gambit of brittle bone disease to venereal disease. Just in case you missed it the more outrageous claim has the hall marks of the dramatically inclined when they claim the fluorides were used by the Nazis to poison the Jewish population. At the concentration that fluoride is added to public water one would have to drink a bath full of water for

6

several days to absorb any level of fluoride to even produce barely visible developing teeth.

I suspect drowning would be an earlier effect.

When I arrived in Britain several decades ago and went to work in east London, I could not believe what I faced in the surgery.

I was disgusted and appalled. I spent a large proportion of my time extracting teeth, endless amalgam fillings or refilling teeth including when dental decay had eaten around previous restoration. Not just in children but in adults as well. Some years ago I spoke to an elderly dentist in New Zealand, who told me that before fluoridation, filling children’s teeth heroically was like trying to fill a bath with the plug out - it was hopeless. When fluoride arrived to much of New Zealand, that changed.

I remember children and adults coming into my East London clinic with swollen

www.dentaltechnician.org.uk

faces and broken-off teeth. They had pus pouring out and were in considerable pain. They had sleepless nights and had to take days and hours off work or school. It was appalling. We used to run a general anesthetic session every Thursday afternoon.

That is not permitted now, because it is done in the hospitals, which have picked up the load that we had to deal with. We would put a number of patients through a huge series of extractions because there was no clinical alternative. That does not occur in New Zealand, Australia or the United States, where there is fluoride.

There are campaigns in a number of areas in the UK. Ex MP Alan Johnston is a leading campaigner for fluoridation of the Hull public water supplies. If you live or work in Hull please contact him and offer your expert help.

PRESTIGE DENTAL

I

have been dealing with Prestige Dental in one of its forms or another for several decades. In truth I am talking about Paul Martin who I’ve dealt with since a change of career beckoned with Percy J Clark/Precious Metal techniques, where he moved from his original role as a dental technician at Mike Kempton’s laboratory in Wimpole Street W1. In this new role, he felt he was able to offer the right technical knowhow - which proved to be absolutely right but he also combined it with a real desire to help so many of the Technicians in the then thriving West End, laboratory market. I can remember phoning him myself, looking for a varnish or separator or wax, or some other quality product I had seen someone use or at an exhibition in Germany. Sure enough he would be able to suggest a very suitable alternative if not the original.

In his early career, Paul handled the CM Gold Alloys and their range of Precision Attachments, working out of offices in Chiltern Street W1. This venue became an informal meeting place, with local technicians arriving to collect their orders and more often than not picking up lunch from a next door sandwich shop, and then staying for coffee and chat.

Many of the best remembered names such as Kedge & Quince, Mike Kempton, Ken Poland, the group from Derek Dental, Keith Rowe, Yateman & Kerwick and many more became Paul’s regular visitors in those halcyon times.

World time v Bradford

Sharing the load Lucy and Paul

Paul established himself very early on as a goto information source. When you were looking, for that specific product, he always understood your inquiry and inevitably would find you the material or product that you needed, even when you were unsure if it existed! He became very knowledgeable on all types of attachments and later co-authored a book with Michel Sherring-Lucas on precision attachment techniques, which became an essential for those labs doing the work. A quick glance at Prestige’s brand new laboratory catalogue, will suggest that nothing has changed about Paul’s knowledge and the company’s understanding of both product and customer. Showcasing quality products, the extensive range from worldwide suppliers is based on the simple philosophy of technical excellence. Although Prestige still help with some of the more everyday items they define themselves by the high end, innovative products sought out to provide their customers a clinical advantage. Moreover the wealth of knowledge and expertise right across the team provides advice and guidance as part of the service, whatever query a customer may have.

I was delighted to be invited to take a look around and meet more of the Prestige team. All very committed, friendly people who all believe in the same thing, helping their customers!

Happy wave of welcome

Language problem: Cockney-Yorkshire

Prestige was originally incorporated in Bradford, West Yorkshire in 1989. It is still privately owned and has been run jointly by directors Paul Martin and Lucy Gabbitas since 2004. Lucy, originally a qualified dental nurse, joined Prestige in 1992 as a Product Specialist and moved up through the company as it expanded. Paul joined in 1996 with Cendres & Metaux & other lab products and a London office. The company quickly expanded, moving into its own premises still in Bradford, and staff numbers increased with its own customer service team and warehouse been established. From an original portfolio of clinical supplies and equipment Prestige has now become equally well known for the quality and variety of their laboratory products. Both Paul and Lucy are hands-on in the company and are well known faces across the dental industry. Two like minded people with a real commitment to provide the service and choice for the interested dental professionals. Meantime Paul has finally moved to live in Yorkshire after spending years on a weekly commute. Having lived all of his life in the south it has become quite an exhilarating change to sample the open air and countryside that Yorkshire offers. He is however still trying to get his head round some of the local lingo.

Today the clinical group of products occupy 70% of the company turnover, supported by 3 field Product Specialists, all with direct, technical dental/lab experience. However with a growing awareness of the laboratory items collection, that may well change. With knowledge, enthusiasm and a continuing drive

Ready for the day

to seek out new equipment and supporting materials that will improve dental techniques and methods, the team is always on hand to help the customer. Very quickly you realise you are in the presence of a whole bunch of equally interested and very professional people. Many have been with the company for a good deal of time. Mick Holt who is in charge of the laboratory sales has been a technician for some years and formerly owned his own laboratory. He now supports lab customers who are into the digital processes. Whitepeaks an American Discs and CADCAM sundries manufacturer are one of their agencies with a really very impressive range of everything for the CADCAM and Digital processes. Mick and his support staff are on hand, enthusiastically working with and helping customers in the field, he is also backed by equally interested office staff.

The company has a real family feel with many of the team working there for a long time including Diane - 20 years at Prestige and Lisa - 17 years. Interestingly these young ladies originally met at school and have known each other since they were 7yrs old!

They certainly always seem to have a smile available whenever you visit. One of the moms has a talented son who draws some remarkable cartoons, often for that special time of year. Such as Halloween, Just gone and an amusing “thank you for ordering the Company catalogue. The whole team really work hard and also play hard.

Charity initiatives are a key part of the Prestige calendar and the company regularly supports Marie Curie raising a total of almost £10k over the last 9 years. The summer event the ‘Bloomin Great Tea Party’ held at Paul’s home is always a sell-out event and this year was no exception. A relaxing and enjoyable day raising funds for this remarkable and very deserving charity,with a great record of helping fund the worldwide fight against Cancer.

The premises are set up with the offices on the first floor and the warehouse on the ground floor run by Andrew who is very well organised with an integrated order and dispatch system which puts the orders directly on to the dispatch log usually same day. The offices also have a fully equipped air-conditioned meeting room, which will accommodate up to 40 people (theatre style), with screen and laptop presentation facilities.

This is providing the perfect venue for a brand new initiative, the brain-child of the Directors of Prestige. Their thinking was that throughout the UK there are several regional study groups, so why not in Yorkshire?

Having canvassed the region, the support and enthusiasm to date has been overwhelming and they now have a full programme of key note speakers for quarterly meetings well into 2019, all of which are CPD verifiable.

Paul & Andrew discuss the rota in the Warehouse

A great example, of the type of specialist equipment available at Prestige would be Denar Articulators. These very soughtafter instruments were first brought into the company by Tony Beale in 1995 and remain very much one of their favoured lines. Working closely with numerous KOL’s, Prestige have for very many years supported the major occlusion courses across the country by investing time and money into a very large loan stock of articulators and

To sum up Prestige are a hardworking, knowledgeable and quality-driven company with real enthusiasm to get it right. In fact the week I did my interview they had just successfully passed their ISO audit. The team is professional and friendly and above all genuinely seem to have fun at work! They all seem to enjoy being there and being part of a very happy bunch of people. No wonder their company motto is “Technically First Class” a boast that Prestige is proud to live up to across the whole of the business. I enjoyed the infectious atmosphere of light-hearted banter and real application to the job and the customer.

face bows. These are available on request to course organisers the length and breadth of the country and are usually accompanied by one of their Product Specialists, Jenni Ball who specialises in everything occlusion. A service instigated by Paul, without which many well-known teachers and courses would be struggling. Individual occlusion kits are made-up for working groups of 3, to represent the patient, dentist and assistant team. It is quite a commitment to money for the stock but Paul really believes that if people can work and learn on the equipment they will continue to want to use it. I do believe he is right but it is an outstanding service for which I am sure many of the course organisers and lecturers are more than delighted. I was amazed at the numbers available and the on going cost of maintaining this invaluable service.

BRANDING AND YOUR BUSINESS IMAGE WHAT IS A BRAND? If you search Google with the above phrase you will encounter countless definitions of what a brand is, no one seems to be able to explain it succinctly. However, we are certain on what it is not, it is not your logo, it is not your name or trademark, even though all these elements and more are encompassed within a “brand” fir your dental business.

To understand what constitutes a brand better I thought this definition helps: “A brand exists only in the mind of your customers. Simply put, a brand is the sum total of all the impressions the customer has, based on every interaction they have had with you, your company and your products” This means that every interaction is important and there should be a consistency of values in those interactions, both human interaction and visual interaction with your products.

With this in mind let’s talk about your packaging and printed material and the delivery of that product to your clients.

Most of you will have invested heavily in marketing your business with a beautiful website which has been SEO’d and you have a social media presence to match. These marketing activities show that you mean business and speak of quality, attention to detail and great customer service.

However, what if someone calls your business and speaks to someone on the phone who is dismissive, comes across as not really knowing much about the business or maybe comes across as being rude?

WHAT DOES THIS SCENARIO DO TO YOUR BRAND? It will cause massive confusion for your client, which could lead to the break down of the

10

My advice is to make your brand strong, smart branded delivery vans, image conscious delivery drivers and a smart branded uniform, or at least a polo top and fleece sporting your brands logo and strapline. A similar model to this is the motor factor trade who deliver products to garages who look after the health of your vehicles rather than the health of the nations teeth! The big nationals are all branded, vehicles, clothing, training and customer service.

Use that model and your brand will be strong.

perception your client has about your business and it’s brand values. Let’s be clear, your brand values will be something you have probably spent a very long time developing and possibly a huge amount of cash!

Another scenario that you may want to make sure doesn’t happen in your business is as follows: Your delivery driver appears at one of your best clients dental practice to whom you deliver high value work. Perhaps your usual delivery driver who knows the practice is off on holiday and you have a stand in who isn’t up to speed with the staff or the way the practice operates, maybe not dressed as smart and possibly just having had a cigarette in the “branded” van in the car park.

When your clients see someone different, not as smart, with the hint of just having had a cigarette, this causes your client to look again, they notice the usual high standard maybe isn’t so high anymore and they may well scrutinise your work more closely?

Again the above scenario might or could dilute your brand and may well cause confusion, the image doesn’t match the product!

www.dentaltechnician.org.uk

The same goes for the packaging and presentation of your product, your high value, highly artistic and skilled work. Gone are the days where you should deliver your work to your clients wrapped in a damp tissue in a plastic zip seal bag, how it is presented and appears to your clients really does matter.

Your work is intricate, skilled and should be revered so give it the platform it deserves.

A well presented piece of work in a simple presentation box, that can be bought cheaply online in bulk, will speak volumes about the quality and attention to detail that you achieve.

The 10p or 20p box, can more than justify its cost, be proud of what you can achieve and show it off even if you have to stick a simple sticker with logo! By considering what your brand is and how your business is perceived at every step on your products journey, you can help your customer be confident that they understand you and your brand values.

Not everyone buys on cost, experience is probably more important, so let your customer understand where you are coming from and show them you mean business with a strong brand.

As ever I am here to help with any of these issues so do email or connect online with me, I look forward to meeting some of you in cyberspace!

LOOKING BACK JOHN WINDIBANK FOA INSIGHT

MEMORIES OF AN OLD CODGER 18 COMMUNICATION & COMPUTERS

T

here used to be a world that I knew in the post World War II years, where talking robots were just something imagined by story tellers.

Communicating was by talking and writing or if you were very lucky and near one, by telephone. Typewriters had been around a long time but for most of us writing was the way and this was done by hand, using pencils or pens with a metal nib dipped in ink. If you had a few bob you used a fountain pen, or a ball point pen which were very new, or as we called them Biros. Ball point pens were looked on as very reactionary and their use was discouraged, especially in schools.

The world had moved on a bit by 1984 when I took on the job of minute secretary for Central Council and by then there were all sorts of typewriters, including electric and just around the corner micro computers were soon available. Things were changing but in hospitals they still used the mechanical typewriters, those huge lumps of impressive mechanical technology that had been around for a 100 years. The communication wheels of hospitals were enabled by hugely skilful women interpreting their notes taken down in shorthand and these were transferred to

paper via a hammered ribbon. One mistake and the whole page would be wrenched from the typewriter screwed up with contempt and thrown into a bin. Needless to say I cultivated their help to produce my minutes and mostly they were very helpful and cheerful although grossly overworked.

To help with the business of minute taking, tape recorders were a help and I would write the minutes out long hand and then shamelessly ask an expert if they would help with the typing. My typing was slow and full of mistakes so I would quite happily ask anyone including relatives, friends and of course the typing pool team if they could help. Typing the minutes with a carbon copy was of course only the beginning of the process for me, I needed over a hundred copies. Photocopiers were just emerging but all that was available to me was an old Roneo duplicator. Duplicating machines have been around since the 19th century and this one looked as though it had been there that long, situated as it was in a room under the stairs in an old workhouse building. Beggars as they say can’t be choosers but I was surprised how well it worked. My helper had cut my stencil and wrapping it around the drum of

the duplicator, we hand turned the first copy to check the page and there it was, a perfectly printed page. This procedure worked well for a while but on one occasion all my helpers had inconveniently avoided me and I cut the stencil myself. There was fortunately plenty of correction fluid available as I completed this patchwork stencil, the result however was a blotchy set of pages I was embarrassed to circulate but no one complained to me, I think they were glad that they weren’t producing the minutes.

This and other problems speeded my change to using computers and dot matrix printers for the minutes, as these were just becoming available at an affordable price for a technician. Computers for the masses had taken off in this country, when in 1980 Clive Sinclair produced his ZX80 computer for less than £100. This device was housed in a plastic flat box with a plastic keyboard with pressure pads, to get a picture you plugged the computer into a TV which presented you with a curser. This little bundle was a microprocessor with a built in basic processing language, 1 KB of RAM and no software to speak of. These little computers seemed to be everywhere but all you could use it for was to write programs, of course with so little RAM they were not complicated but people were moving dots around the screen and creating games.

Well this was just the beginning, better models followed every year from multiple companies including the BBC and this came with lots of software. My son acquired a Sinclair Spectrum with which he astonished me and he now earns his living as a programmer director.

Nineteen Eighty-Four and Alan Sugar (now Sir Alan) entered the field with his Amstrad CPC464 computer with a built in tape memory recorder and it also came with its own monitor and undercutting the price of all the opposition.

The following year I purchased a CPC with a built in floppy disc drive and the same year Mr Sugar produced his PCW (Personal Computer Word Processor) and a dentist friend of mine purchased one for his practice and asked my 17-year-old son (still at school) to write a program for him and paid him more by the hour than I was earning. The programme was a great success and it was used to my knowledge for 12 years, but back to the plot.

www.dentaltechnician.org.uk

Back in the eighties I was keen to do more with computers than write letters, so I tried to compile a program to record the records we kept in a lab and print out reports and lists. I persuaded my son to write the interface and I crudely programmed the functions to go with it and it worked very well but unfortunately I hit the major problem at that time for programmers and that was the lack of memory to run the programme. I really liked that CPC computer, it fired up instantly with no waiting about before I could use it and it kept all my Central Council data I had accrued over the years.

racing handicaps. This was a DOS program called Q&A designed by Symantec who these days specialize in anti-virus software but back then Q&A was their big seller worldwide.

This software was basically a flat-file data base spread sheet with a built in word processer and programming tools to lay out and access cells within the data base. I was pleased with the program but then the Medical Devices(MD) legislation hit the scene I knew how I wanted to proceed with this administrative change.

I could envisage how I wanted to manage it all but it would need an awful lot of work to rewrite my program and I hadn’t even got a computer in the lab to use.

I knew it would take a lot of time, so I set aside my lunch breaks, locked myself into a spare office and set to. I took the best part of a year to come up with a workable program I was happy with and in the mean time I worked on the hospital admin to get me a computer and printer. I used the medical devices as an argument and eventually they came up with an old computer, but it was

So in the nineteen nineties I bought my first personal computer with its DOS (disk operating system) and by this time the original windows program had been introduced which as they said, sat on the top of DOS. This came with some excellent software called Ami-Pro which was a word processor that also included an incredible graphics package which enabled me to draw dentition and from this I designed the prescriptions we used at our Hospital. I was still however looking for a program to use in the lab and I found it of all places at the London Boat Show being demonstrated by a guy selling a program for working out dinghy

just right for what I wanted. Using my own software, I set up the program and I informed the admin that we were now MD compliant. Administrators if they are any good know how to cover their backs, and as they did not know one end of a wax knife from the other, they employed an expert to look at what I was doing. The expert wrote a neat report for his money, recommending minute changes and then asked me If I could work with him while presenting lectures on medical devices, £100 be enough? he said.

Well nothing came of that and I asked my line manager what other departments had done about MD, oh nothing he said we got in the experts to organise their departments.

Well the expert looking at my program charged them £3000 so heaven knows what the cost to the health service was for implementing this legislation. My program is still being used at my old hospital although with operating system upgrades some of its functions stopped working and they are looking for a replacement, but a bit more on this subject with my next memory.

INSIGHT

New software was coming on the market all the time and I purchased a very good word processing package which solved the problem of the minutes. The printed output however was very poor with the 9 pin dot matrix printer (DMP) I had acquired and even with a double pass of the printer head the quality was not the near type face quality that the manufacturers were claiming. Things improved when I purchased a “Star” 24 pin DMP which included a gate drive for label printing which was a huge improvement.

The letter and graphics printing were vastly improved and I continued to use the printer for labels until I retired in 2003. The printer that really solved all my printer problems was the Hewlett Packard Laserjet 4, which I bought in 1993 and this produced 600 dots per inch and incredible seamless graphics.

This is the printer my wife Mavis produced the OTA magazine for a while when she was its editor and I wrote my first Old Codger series, that one on tags.

LET’S TALK

DIGITAL

Our editor Larry Browne talks to Mosin Aboobaker, Digital Product Specialist at Henry Schein Dental/ConnectDental about his role in helping his customers navigate the current digital market

DIGITAL DENTISTRY

D

uring the BDIA Dental Showcase 2018, that was held at London’s Excel in early October, I had the opportunity to visit the Henry Schein Dental stand to see the vast array of digital equipment and materials they provide. They really do offer such a choice and I was very interested in speaking with the person who has the responsibility for dealing with the digital restorative options for both the laboratory and clinic.

I was introduced to CAD/CAM specialist Mosin Aboobaker, whose primary responsibility is to promote and support Henry Schein’s digital systems as well as oversee the training of the clinic staff or the laboratory to be fluent with the various options. Mosin is an expert in digital and 3D printing, and quite knowledgeable about the market and the individuals with whom he needs to communicate.

He was clear in saying a digital system should suit the customer and he has the foresight to suggest what the potential user will need to be instructed in to what best suits his needs. He pointed out that a customer’s assumption that the most complex system or the most inclusive system is always best. However, based on his experience, he knows that this may not always be the right option or direction for the practice.

The advantage of Henry Schein’s comprehensive portfolio of digital options is that a workflow can be customised or tailored to a client’s specific needs. The potential buyer

14

of the equipment may not fully understand the options available and will perhaps opt for a system very much ahead of their understanding or something unnecessarily complex. Mosin feels strongly that people should only buy from a company they can trust, and, most importantly, who offers training to further ensure that the buyer develops the confidence to both learn and use the digital processes. This means the system they eventually choose will be used regularly and not become an expensive door stop.

Mosin stressed that discovering what the potential customer is really concerned about is essential to ensure a happy relationship and to inspire confidence for the purchaser.

He was quite clear that the clinical market for digital is growing rapidly with the clinician able and willing to invest in the latest scanners and milling equipment. This has meant that laboratories are now, having to look very seriously at their current workflows. The clinician’s scan is sent out to whoever can cope with it and if the laboratories are not investing in digital then the work will be left to those who can cope. He realised it can be more difficult for some labs, especially the smaller ones, to find the capital investment, but suggest that they probably have existing clients who may have already bought a scanner and are looking for the laboratory service to match. They need to be ready to provide this digital service and Henry Schein is here to help them do just that.

The modern intraoral scanning process is so much more attractive for patients than traditional impression procedures with the systems providing at least the same accuracy, without the discomfort for the patient. He agreed with me that any lab, regardless of size, need to seriously consider buying into the scan and design aspects of the digital process.

The required manufacturing procedures can be done by a third party to the technician’s individual design, either a commercial digital supplier or a friendly laboratory with a similar

www.dentaltechnician.org.uk

system. This way even the smallest laboratory can compete and at the same time look to grow their client base.

Mosin and I spoke about the material choices now available, such as Zirconium crowns, which can be made to the complete size and shape, ready for staining if required, with the potential for building onto the base to produce a very individual aesthetic match. These materials also mean that precious metal costs can be discounted, because the quality of bonding and aesthetics of the modern materials is so very good. For some it may be seen as a quick get-out but in fact the techniques and results leave little doubt that the future is digital. It is also clear that the clinician may need his technician even more than before to help guide them through the restorative laboratory techniques.

Teaching the client the suitability of the available systems and introducing them to the new modern materials and methods is quite an undertaking. Mosin is confident the Henry Schein digital choices and the Company’s skilled technicians and support staff provides a real edge over the competition. With a strong commitment to continuing service he is confident they have the combination right.

Thank you Mosin and the Henry Schein Dental team for your time and information.

THE DENTAL TECHNICIAN MARKETPLACE CONTOURING, FINISHING AND POLISHING IS MORE THAN JUST “THE ICING ON THE CAKE”. ABRASIVES: THE SURFACE QUALITY OF CERAMIC DENTAL RESTORATIONS IS BEST IMPROVED USING A SYSTEMATIC APPROACH

BY DR MARKUS TH. FIRLA, HASBERGEN-GASTE, GERMANY w The final, intraoral use of abrasives to anatomically and functionally improve the surface quality of all-ceramic dental workpieces is not easy for dentists, especially in the case of CAD/CAM restorations milled from “industrially prefabricated” zirconia or lithium disilicate blocks. Efficient extraoral finishing of such restorations in dental laboratories should not be underestimated either.

The objective of both steps is to give ceramic restorations occlusal surfaces which are as smooth as possible, in harmony with natural occlusion, and anatomically and functionally correct.

Today, experts agree that all-ceramic CAD/ CAM restorations, particularly single and partial crowns, veneers, and bridges, are best finished with diamond rotary instruments, even though - depending on the CAM system used - laboratories frequently rely on carbide instruments in the basic fabrication process.

In contrast to the milling of all-ceramic dental workpieces from prefabricated blocks, the subsequent finishing procedures performed in laboratories and, mostly intraorally, in dental practices are de-signed to reduce material in the submillimetre or micrometre range. For this minimal treatment, diamond finishers and polishers are the tools of choice; they remove material gently, but efficiently, because instruments coated or impregnated with coarse, medium or fine diamond particles ensure uniform material reduction with continuous and accurate control.

Diamonds are the only instrument type allowing users to achieve surface roughness values compa-rable to those of glaze-fired ceramics, from the FIG 1

FIG 6

contouring step, which creates the final shape of the workpiece, to the finishing step, which determines the surface texture, and the prepolishing and high-gloss polishing steps, which complete the process.

In addition, the use of diamond rotary instruments to contour, finish and polish dental ceramics substantially reduces the risk of causing microscopic or macroscopic cracking, or even chipping.

The smoothness of a ceramic surface is not only crucial to its gloss, and therefore to the aesthetic result; it also has a second effect, which is equally important. The smoother the ceramic surface, the less likely the occurrence of negative mechanical influences on the ceramic material caused by the antagonist. Likewise, a smooth ceramic surface minimises the abrasive loss of natural enamel of the tooth opposing the restoration.

These phenomena need to be considered when working with all-ceramic restorations, especially if they are made of zirconia or lithium disilicate, because the desired hardness of these materials, and also their brittleness, should not be neglected.

The dental manufacturer Shofu has recently launched the ZiLMaster system, comprising two kits of instruments specially designed for contouring, finishing and polishing all-ceramic restorations made of zirconia or lithium disilicate. The kits are coded CA (contra-angle) for intraoral use by dentists and HP (handpiece) for extraoral use by dental technicians.

For both kits, selected shapes of Shofu’s comprehensive and time-tested range of Dura-Green DIA diamond stones have been combined with various shapes of newly designed diamond-impregnated silicone polishers.

The different - directly and specifically matched - diamond grits of the Dura-Green DIA instruments and the coarse, medium and fine ZiLMaster polishers excellently complement each other in the con-touring, finishing and high-gloss polishing procedures, ensuring a very quick and easy workflow.

USING CAD/CAM FOR A COMBINATION APPROACH TO FULL MOUTH RECONSTRUCTION BASED ON AN ARTICLE FROM INTERNATIONAL DENTAL TRIBUNE

DR. ARA NAZARIAN DICOI (Diplomate International Congress of Oral Implantologists) 1857 East Big Beaver Road, Troy, Michigan 48083, United States Email: drnazarian@premierdentalcenter.com

W

e are in an age where the potential and necessity of working closely with our clinical colleagues is much easier and much more required. The Digital processes fit perfectly into the team approach to restorative procedures and allow trouble free exchanges of vital and direct information, which greatly enhances the potential outcomes. From diagnostic procedures through to material choices a greater degree of quality can be achieved as a result of the communication potential.

Almost trouble free examination, on screen of the initial scan and the potential design and most suitable materials can be carried out within minutes of the scan being received by the laboratory.

CAM technology, laboratories and their dentists can collaborate directly regarding the aesthetic and functional characteristics required. The ceramist can then complete the restorations using stains, glazes, and colours to finalise the restorations.

The great increase in the material choices as a result of the digital technology adds to our ability to produce strong yet aesthetic restorations. One of the really exciting materials to reach the market is Zirconium.

Now very much the monolithic answer to aesthetic, yet strong restorations.

CASE REPORT

Simultaneously, other advances in technology and material science have provided dentists and laboratories with restorative zirconia options that can be cost-effective and aesthetic alternatives when full-mouth rehabilitations are needed. In fact, computer-aided design/ computer-assisted manufacturing (CAD/CAM) makes it possible for laboratories to collaborate with dentists to deliver monolithic zirconia restorations with individual characterisations that demonstrate high flexural strength and excellent long-term stability (e.g. Zenostar, Wieland, Ivoclar Vivadent). [6-8] Because this material can be milled at the laboratory from single blocks using CAD/

Overall, the foundations of this collaborative process are the digital CAD/CAM and communication technologies (e.g. digital photographs, digital radiographs, intraoral scans, 3-D restoration design software) that enable laboratory technicians to virtually design the zirconia restorations. These same technologies also facilitate the workflow by powering the milling of monolithic blocks into crowns and bridges, with subsequent sintering and stain characterisation requiring less time. [7, 8]

Before treatment

A woman in her mid-60s was referred to the dentist because she was dissatisfied with the appearance of her smile. The initial diagnostic evaluation during the first appointment included a series of digital images with study casts, centric relation bite record, face-bow transfer and a CBCT using CS 8100 3D (Carestream Dental) Pictured right.

www.dentaltechnician.org.uk

The examination revealed several maxillary teeth with worn composite restorations, cracked or leaking amalgam restorations, recurrent decay at the margins of existing restorations, and abfractions with cervical decay. Tooth #12 had a periapical lesion due to a failing root canal and periodontal disease with class II mobility. Existing crown restorations on teeth #20 and #28 had recurrent decay on the facial aspects, with recession. Teeth #21 and #29 had large amalgam restorations with deteriorating margins, as well as cracks present. Although no restorations were present in the anterior mandibular teeth, there was severe incisal edge wear due to possible grinding and parafunction.

TREATMENT PLANNING Guide and fabrication template

Initial preparations

After reviewing the clinical findings and mounted models, the patient was diagnosed with a restricted envelope of function and decreased verticaldimension from continuous wear. To develop a treatment plan and determine if the vertical dimension could be increased, the laboratory fabricated a diagnostic 3-D White Wax-Up, along with a preparation guide and temporisation fabrication template, based on all of the analogue and digital records that were transferred from the dentist.

It was determined that the maxillary central incisors could be lengthened by 1.2 mm to improve the aesthetics, and the Virtual Diagnostic wax-up canines would also be lengthened to restore canine guidance in lateral excursions. Overall, vertical dimension would be increased by 1.5 mm. For the lower anterior, the goal was to correct the length-to-width ratio and create a less worn appearance. It was further determined from the diagnostic wax-up that aesthetics and function p18 could be enhanced by restoring

u

the remaining dentition. Since tooth #12 required an extraction, replacement options were discussed with the patient.

Further evaluation determined that the patient would require block grafts in the areas of teeth #18 and #19, as well as #30 and #31, to enable implant placement. In the maxillary arch, placing implants in the molar regions would require sinus augmentation, but implants could be placed in the #4 and #13 positions without major bone grafting procedures.

The ultimate treatment agreed to by the patient consisted of splinted monolithic zirconia (Zenostar, Wieland, Ivoclar Vivadent) crown restorations from #5 to #12, with #12 being a distal cantilever pontic. In the areas of teeth #4 and #13, dental implants would be placed, followed by their corresponding custom abutments and crown restorations. In the lower arch, the teeth would be segmentally connected with splinted crowns: premolars, separate canines, and then incisors.

Provionals from wax-up

According to the manufacturer, the selected zirconia material combines excellent flexural strength with the aesthetics of natural tooth shades. In this particular case, the patient desired a 040 bleach shade (Ivoclar Vivadent Chromascop). Zenostar is especially suitable for making monolithic restorations, but can also be used as an aesthetic framework material for a layered technique. [4-8] SURGERY AND PROVISIONALISATION

adequate reduction for the definitive zirconia crown restorations. Full arch impressions were taken using polyvinyl-siloxane impression material (Panasil, Kettenbach), along with a bite relation using a jig fabricated on the 3-D White Wax-Up models. A shade was also taken, photographed, and later transferred to the laboratory.

Then, using a matrix impression (Sil-Tech, Ivoclar Vivadent) of the 3-D White Wax-Up, a provisional restoration, which would aid in determining the best size, shape, colour, and position for the definitive restorations, was made using a bleach shade of temporary material. After the patient returned a few weeks later for evaluation of aesthetics, phonetics, and bite, the dental laboratory was instructed to replicate the 3-D White Wax-Up when fabricating the definitive restorations.

LABORATORY DESIGN AND MANUFACTURING The 3-D White Wax-Ups, colour photographs, impressions, and bite relations were forwarded to the dental lab (Arrowhead Dental Lab), along with specific instructions regarding the size, shape, and colour of the restorations. The laboratory technician scanned the 3-D White Wax-Ups in order to select the appropriate arch form, tooth size, and occlusion from the digital options available in the treatment planning software.

Once a virtual model was created, the full-contour restorations were digitally designed, and virtual images of the proposed reconstruction were forwarded through 3Shape Communicate to the dentist’s e-mail for review and approval. Any minor adjustments in tooth shape and contour were sent back to the dental technician so that the most ideal aesthetic and form could be achieved.

Finished porcelain from Laboratory

A tooth-supported surgical guide (3D Diagnostix) and Guided Surgery Kit (OCO Biomedical) was used during the osteotomies followed by dental implant placement of dental implants (Engage, OCO Biomedical;).

Tooth #12 was atraumatically extracted using Physical forceps and the socket grafted with a putty blend of cortical mineralised and demineralised bone grafting material, followed by a pericardium membrane and primary closure by suturing the tissue with 3.0 mm silk sutures; and the remaining teeth prepared for crown restorations. Any old amalgam restorations or indications of recurrent decay were removed and cored, and any necessary endodontic therapy was performed (Fig. 6).

Once the final design and adjustments to the zirconia restorations were completed, the appropriate monolithic zirconia block(s) were selected and milled. After milling, minor adjustments were made while the restorations were in the green state, using only grinding instruments. Little or no pressure was applied during this process, but water was used to prevent excessive frictional heat from fracturing the zirconia.

At the time, the laboratory provided the 3-D White Wax-Up, a clear reduction guide was also delivered and then used to ensure

The internal aspects of the restorations were sandblasted with 50μm alumina at 50 psi to enhance adhesion and cementation,

after which contaminants were removed using steam or ultrasonic cleaning for 15 minutes.

Zirconia surfaces must be free of dirt, milling dust/residue, and oily-greasy elements.

After the restoration’s surfaces were cleaned, they were sintered appropriately, and any characterisation with stains and glazes was performed. The restorations were hand polished, evaluated and returned to the dentist for cementation.

U/Anterior and lower restorations in situ

Four months later, the healing caps were removed from the implants in the #4 and #13 areas (Fig. 12) and ISQ values tested using the Osstell unit. Since the readings were very favourable, impression posts were inserted and full arch impressions captured for use by the laboratory in fabricating the final crown restorations and custom abutments. The laboratory was able to scan impressions, and use digital file splitting to simultaneously design the custom abutments and crowns, and then precisely mill each component to the required parameters (Fig. 15).

Implant Positions Ultimately, the custom abutments were placed and torqued two weeks later and the crown restorations were seated to complete the case (Fig. 16).

Abutment impression analogues

CONCLUSION

A systematic method for treatment planning, material selection, tooth preparation, and cementation enables dentists and laboratories to effectively and efficiently address patient needs. In the case described here, the patient was very pleased with her smile rehabilitation, in addition to being able to receive all of the necessary treatment procedures at the same practice. With a technologydriven and digitally supported collaborative relationship, laboratories and dentists can achieve such outcomes more routinely, predictably, aesthetically, and functionally.

HELD AT EXCEL CONFERENCE CENTER IN LONDON

T

he earliest part of the month saw the arrival of the three day meeting conference and exhibition for the BDIA in London. One of the major chances to meet with the Companies exhibiting and look, feel, and argue about their products and equipment. As outlined in an earlier editorial in this journal the assembled members are truly representative of the clinical market place but with very little to attract Technicians. Those of us who may work within clinics or in the hospital situation would possibly be interested but as a visit to update your laboratory materials etc. it offered very little. It is always good to greet old familiar faces who may be attending and also see the technicians who are often manning the various stands. I try not to miss these occasions and found a few things to pass on for your interest.

Luckily there are always a few areas worth a mention, so here goes.

How about a new approach to the great tooth enemy Sugar? TePe have now take the sugar cane and used it as a raw material to make toothbrushes!! It was quite a good presentation and of course a brave course. But the well-trained staff assured me of the quality of product and commitment to dental health.

Certainly, a new approach.

Fighting the Enemy, with the Enemy

There are of course some areas where the equipment or materials are shared by both clinician and technician. One such area is of course the magnifying loops and spectacles required in modern restorative techniques.

Hilliers Vision are specialists in supplying the medical and Dental profession with their various choices designs.

Looking for Loops?

There were of course a number of manufacturers who promote their digital options and a good many chair-side and laboratory scanners were on show. Some familiar names and a few others, but lots of choice.

Dental Directory, Ivoclar Vivadent, Ivoclar VivadenIVt

Always good to meet with old friends again and to smile at the fond memories of the Vita porcelains and all their innovations over the years. Their shade taking machine continues to attract buyers and interest.

Julie now back on her Shofu stand, busy dealing with interested customers. With a special place for their wonderful patient camera which records a accurate shade as well as customised images of the patient. Together with their wonderful, choice of porcelains and composites.

Henry Schein were there with their extended and very large collection of Digital options for both Laboratory and Clinic. A very interesting stand offering lots of choice with quite an up to date mixture of systems to suit all tastes and needs. If you want to look at a choice of systems and are interested in perhaps mixing milling from one source and scanning from another or some other mix then this would be a good place to start.

Derren Neve continue to work hard promoting his VALPLAST innovative flexible denture base material and his range of model trays which keep him busy throughout the year at RDT Technology. He is quickly joined by colleagues including Julie from Shofu, Lord Allan Wright (Dental Technicians UK) and of course Blueprint Dental and Sonja Jones from RDT Technology. You can’t keep a good thing to yourself!!

Shottlander were there with quite a display of their excellent collection of denture teeth and of course their composites and stains and their temporary bridge materials together with their Doric impression materials.

An large attractive and well lit stand with lots of room to demonstrate and explain.

Just along was the PLANMECA stand with a feature on the “FIVE GO FORTH” charity cycle ride completed by Chris Barrow. Les Jones, Sheila Scott, Simon Tucker, and Ashley Latter. And a glutton for punishment Les Jones was on a what bike fully geared up still collecting for charity. This after completing the ride from John a Groats to Lands end. Had to contribute!! Can You?

GC were their with their innovative clinical products with lots of room for demonstrating and talking with their interested visitor.

They were demonstrating their chair side scanning equipment nd their very popular injectable composites.

“We will all be touched in some way by cancer in our lives, so supporting the work of Cancer Research is something everyone can get behind.

We’ve also chosen two special charities within the dental sector. Bridge2Aid does amazing work in Africa training local medical officers to carry out basic dentistry and, as a result, helps thousands of people out of pain and suffering. BrushUpUK is a charity that believes that everyone should have the knowledge and skills to access and maintain a good standard of oral health and works with professionals within the sector to provide education and guidance to vulnerable groups in society.”

www.dentaltechnician.org.uk

Perhaps a novel presence was a stand representing Brazillian manufacturers with Orthodontic Brckes, Implant system, clinical equipment, for scanning and radiography as well as operating chairs and the full gamit of clinical furniture. Truly added an International flavour.

An interesting and informative visit. A great deal for the clinicians and those involved in dental offices but a few bits and pieces to appeal to the interested Dental Technician.

SALARIES SURVEY RESULTS FROM ANDY FOSTER AND MARSHALL HUNT RECRUITMENT FOR 2018

2018 UK DENTAL TECHNICIAN SALARIES SURVEY AN INTERESTING AND WIDESPREAD FEEDBACK FROM TECHNICIANS ACROSS THE COUNTRY INTRODUCTION Marshall Hunt Recruitment have conducted the 2018 Survey of UK Dental Technician salaries.

“This year we achieved 524 responses, a significant increase on 2017 which has allowed us even greater clarity”.

The survey helps shed light on the dental technology sector, the roles within it, gender split, GDC registration, job satisfaction, and of course, pay.

SURVEY QUESTIONS To achieve a broad spectrum of results, we focused our search on the main roles within the lab environment, including ceramists, prosthetics, orthodontics, CAD/CAM, management, trainees and more.

Here are some other highlights from this year's results:

Respondents were also asked a selection of questions regarding salary, experience, healthcare benefits, company pension schemes, job satisfaction and more.

Remuneration The majority of respondents that took part in our survey (almost 20%) are earning a basic salary between £20-£24k per annum.

A small number of individuals are earning salaries at the higher end with 5% of respondents being paid over £50k.

Of this £50k+ group, the three highest categories were lab owners making up the majority with 33%, then ceramists (23%) and prosthetics technicians (16%). 50% of all survey respondents believe that the remuneration package they receive from their employer is average compared to other technicians. 29% of respondents are of the opinion that their remuneration package is below average.

Gender 71% of respondents were male (371 respondents), and 29% female (153 respondents.) The survey showed that the average salary for experienced (5+ years) male and female respondents is £33k and £28.5k per annum respectively, a difference of 13%.

Job Satisfaction 53% of respondents said that they are satisfied in their current role, with 15% being very satisfied.

19% were dissatisfied in the current role, and 28% with neither satisfied not dissatisfied.

GDC Registered 76% of respondents were registered with the GDC.

20

Prosthetics Technicians were the largest group of respondents with 32%, followed by ceramists and then CAD/CAM technicians.

We were able to extract revealing data for each job role in the dental lab environment.

For example, when analysing data from ceramists with 10-14 years lab experience, we can find that:

• 41% were satisfied with the workplace flexibility offered by their employer, and 37% are satisfied with the amount of paid leave that they receive.

• Just 16% of the group were satisfied with the healthcare benefits that they receive • 17% said that they were satisfied with the pension scheme offered by their employer.

• 58% are happy with the opportunities they get to apply there talents and expertise.

• 37% say that their employer is dedicated to their professional development.

FULL SURVEY REPORT The full report of the '2018 UK Dental Technician Salaries Survey' will be available at www.dentaltechnicianjobs.net on October 31st.

• The majority (25%) are earning between £30k - £34k per annum.

• 79% of respondents in this category were male.

• 54% were GDC registered.

• 29% are satisfied with their overall remuneration package, although 25% believe that their remuneration package is below average when compared to other technicians with similar experience to themselves.

• 20% were happy with the additional benefits offered by their employer.

CHAIRSIDE CAD/CAM IMMEDIATE RESTORATIONS

Dr Xing Liu

BY DR. FENG LIU AND DR. XING LIU PEKING UNIVERSITY SCHOOL AND HOSPITAL OF STOMATOLOGY PEKING, CHINA FROM DENTAL TRIBUNE INTERNATIONAL. OCTOBER 5, 2018

N

The overall structure of ultra-thin veneer is flexible, in that its neck can gradually change from thick to thin, and the border can be knife edge. Or thin round and convex.

The virtual mode, which is widely used for restoration design, has target contours such as wax-up. In this mode, the operator should scan the original tooth shape in the mouth, or the model, then wax up and re-scan the wax-up shape into the CEREC system. Both optic impressions will transfer into the virtual model, and match to each other to obtain the restoration contour information required.

Depending on the 3-D data, chair side milling can be complete in few minutes. Post-milling processes shaping and polishing may be necessary or additional staining and glazing.

Manufacturing inlays, onlays, crowns and veneers chair side with a CAD/CAM system has become established in most dental offices. This technique can produce immediate scan, design, milling and restoration quickly and conveniently.

It is the same for the no-preparation ultrathin veneer chair side CAD/CAM systems, of which CEREC is the most developed.

CASE REPORT A 57-year-old female patient presented, whose dentition had apparent colour changes and abrasions that had occurred gradually over time. These problems resulted in a non-aesthetic smile and made her appear older. She also made a request for a highly comfortable and minimally invasive treatment

o-preparation ultra-thin veneer is one of the most minimally invasive restorations. Its thickness ranges from 0.3 to 0.5 mm. In the right circumstances it can show excellent aesthetic appearance and provide long-term stability and health of soft- and hard tissue. Dr. Xing Liu

plan and expected an improvement in the colour and shape of her upper anterior Dr. Feng Liu teeth, which would rebuild her smile and self-confidence.

It was found that due to the abrasion which had occurred over several decades, the labial surface was plain and flat, the incisors had been worn to a straight line and also had abrasion-associated defects. The nopreparation veneer that would occupy the “outer space” of the teeth would eliminate the slight wrinkles around the lips. These effects were part of the patient’s expectations and the treatment plan was accepted.

Four year follow up

Veneers

The patient wanted her teeth colour to seem natural and to disguise the discoloration. The treatment plan was confirmed as CEREC designed and manufactured Mark II (VITA) veneer of 0.3 mm thickness, 1M1 shade, and the material was chosen for its excellent aesthetic performance and translucency.

The manufacture of no-preparation veneer could depend on the precise wax-up of preoperation. This step could save the patient’s chair side waiting time; the Virtual technique can simplify the design process; milling the restoration with a 0.5 mm original thickness and polishing after milling will decrease the risk of milling defect.

The exact process can be concluded as: 1. Obtain a precise pre-operation impression and make the model. Use a CEREC scan to obtain information about the abutment teeth.

2. Depending on the DSD result, make a wax-up on the pre-op model. The thickness of wax-up should be from 0.3 mm to 0.5 mm.

Get the biocopy scan of the wax-up model and match accurately with the pre-op model

3. Setting the margin of the abutment teeth, the marginal edge line is not fixed because of the no-preparation technique. The direction of insertion should be defined first, which can cover most areas of the labial surface, incisor edge and adjacent surfaces. The border of the covered area should be the margin of the restoration.

4. Shape formation of the restoration: Copy the target shape of the Virtual model, the restoration should be calculated automatically. If there is any defect, it can be adjusted and corrected by the tools. If there are any areas not thick enough for 0.5 mm, it should be added to 0.5 mm to avoid fractures during the milling process.

5. Modification and polishing of the initial restoration to 0.3 mm thick after milling.

And fine polishing of the final restoration.

6. Intraoral try-in, fine adjustment and cementation.

7. Four-year follow-up and recheck. The restorations are as excellent as before and the margins are tightly sealed, the colour is stable, there is no margin colour or whole colour change The patient is very satisfied with the aesthetic performance and function.

A charming smile appearance has given her more confidence and vigour.

CONCLUSIONS The no-preparation veneer is a kind of restoration with high precision requirement and manufacturing difficulty. It is usually finished in a laboratory. Benefitting from chair side CAD/CAM techniques, immediate restorations in one appointment can be achieved; dentists can invite the patients to observe the process of restoration design and manufacture, and even get involved in the design. Patients may feel that they are participating in the treatment, establishing an emotional connection with the restoration, which may also make them more easily accept and love their restoration. The value of increasing the satisfaction should not be ignored.

Virtual Model (Biocopy) design is the combination of traditional aesthetic design and digital virtual design. It is also the most convenient and fast technical route. Nowadays, 3-D virtual technique is becoming more and more established. Using 3-D techniques directly to make a virtual design may also get wonderful restoration performance, it can be predicted that this pattern will become the mainstream of digital aesthetic design in future.

DENTAL TECHNICIANS INSIGHT

DANGEROUS ROLE IN WW2 PART SIX

BY TONY LANDON

GENERAL EISENHOWER LEARNS THE GRIPE, IS DENTURE REPLACEMENT The importance of an adequate U.S. Army prosthetic service as a morale supporting factor was unexpectedly demonstrated by written embarrassing experiences that were brought to the attention of their General Dwight D. Eisenhower’s, no less, towards the end of the North West African campaign theatre in 1943.

The Moroccan, Algerian and Tunisian offensive 1942 campaigns were launched at a time when earlier physical standards had been drastically lowered to enable the U.S. authorities to have sufficient troops for their planned landing assaults. U.S. soldiers were being shipped overseas for their combat missions before completion of their dental work. Portable dental laboratories had not been supplied in sufficient numbers and those that had been carried forward to camps had then been removed from a large number of the combat zone medical centres.

The terrain of the battle area in Tunisia North Africa

The determined Allied forces swept through Tunisia in under a month

Consequently the U.S. Army prosthetic service in North Africa was at a low ebb in 1943. General Eisenhower had asked that U.S. mail censors to tabulate the complaints noted in soldiers' letters that were being sent back to their loved ones across the United States. To the astonishment of all concerned their U.S. Dental Service took first prize with "gripes" relative to the inability of manufacturing and supplying dentures or repairing broken appliances.

The fact was these newly recruited U.S. troops were experiencing their first taste of war time action as part of their proud United States of American forces. They felt let down that reality didn’t meet their expectations in the overall theatre of war. They were more voluble about their difficulties of obtaining dentures than about defects of food choice for their meals or the discomforts of operating up front in combat.

Both U.S. and British commanders were concerned about their Anglo American Allied troops’ morale. It was not going to be a straightforward task to positively motivate these fighting veterans of the various recent desert campaigns for further engagements.

They had endured ferocious fighting hand to hand such as around the hills of the bloody Djebels and Tebourba gap. They were to be immediately formed up with new recruits for their next planned offensives, which was supposed to be on the “soft under-belly of Europe, Italy via Sicily” as Prime Minister Churchill so erroneously described it.

Continuous fighting, month after month, year following year pushed assault troops to their limits. Acute stress was a natural consequence of such relentless fighting. Even those well trained and self-disciplined found it near on impossible to face going into attacking action again.

Divisions with battle experience fought in the full knowledge of the inescapable fact that to continue fighting against a determined enemy meant inexorably and inevitably many soldiers developed an anxiety neurosis. Their courage and resolve to fight was diminishing.

All troops were fully aware what it meant individually to them to be involved in war.

26

www.dentaltechnician.org.uk

There were however some boosts to soldiers moral, for if they were wounded there was the tremendous positive effect of the new administered drug, penicillin. Plus and it was a big plus, the wounded soldiers appreciated more than anything else the caring attendance of female nurses close to the front lines.

Female nurses were never that far from the front lines from El Alamein right across to Tripoli a distance of 1500 miles. In Causality Clearing Stations the gentle hands and soothing words of the nursing sisters was received with such gratitude from the wretched dirty and blood caked wounded. Especially the terribly burnt tank crews half roasted alive in their shattered tanks. The expressions of relief as the wounded lay on their sick beds tended to by female nurses was unforgettable.

The 78th Battleaxe Division and Churchill tanks of the North Irish Horse made a tactical surprise attack on the defending enemy of Longstop Hill, which was the formidable last defensive position in the Tunisian mountain area. The dug in enemy had not anticipated Allied troops would be supported all the way to the summit by their tanks.

During the long month of April 1943 seven hundred wounded soldiers had been air evacuated. In total from North West Africa seven thousand wounded were flown out across the Mediterranean Sea to Gibraltar, Britain or even right across to Northern America.

SITED NEAR COMMAND CENTRES DENTAL UNITS WERE SUBJECTED TO ENEMY FIRE

INSIGHT

The U.S. Army division laboratory would normally be situated with the rear medical centres. Whereas dental forward units with their own electrical 3-KVA generators in tented marquees would be set up near the battle clearing station and command post.

They would be moved on short notice to another location where they were more urgently needed.

The problem of being close to the front line usually from a logistics point of view on the same location as a command post was the long range shelling, mortar bombing and possible sniper fire the actual operational centre could be repeatedly subjected to. Although the Geneva Convention of a Red Cross on a white background was always prominently displayed on casualty clearing and dental clinics / laboratories marquees and buildings and mobile field unit trucks. Their Red Cross status should have been observed, this wasn’t always the case.

Too often dental technicians working in forward laboratories or taking on the role of stretcher bearers to retrieve the injured servicemen were subjected to enemy fire due their location close to command centres or soldiers moving forward in skirmishes.

The Geneva Convention of personnel identification for a non-combat medic was a sleeve Red Cross brassard to be worn high up on the left arm. (Note image top right) Enemy soldiers perceiving approaching soldiers shot on sight. Too many stretcher bearers were being killed or severely wounded as their identifiable arm stating they were non-combat service personnel wasn’t always clearly visible.

German medics and stretcher bearers wore two armbands and a large white body tabard that had a foot high, wide red cross on the front and back. They were easily identifiable.

Eventually during the last year of WW2 battles in Northern Europe, the Geneva Convention acknowledge both arms should have Red Cross arm brassards and helmets for medical personnel should clearly display right around their helmets the Red Cross signs.

DENTEAM CPD PROGRAMME TO OFFER

‘SOMETHING FOR EVERYONE’ CPD

l

A new regional CPD event for the south-west will be held next year, featuring a range of sessions tailored to dental technicians. DenTeam 2019 will take place at the Sandy Park Conference Centre on the outskirts of Exeter on 21st and 22nd June 2019. DenTeam is about ‘team members learning together’, says event organiser Teamwork Professionals.

Directed by two former editors of The Dental Technician magazine, Chris Ritchie and Derek Pearson, and put together in association with the Dental Technologists Association (DTA), the programme will cover the main core CPD subjects applicable to dental technicians along with a range of smaller seminars and workshops on everything from taking and working with better impressions to getting the best results with zirconia.

Chris comments: “We’re really encouraging the team learning approach with DenTeam. All delegates are welcome to attend any sessions they like, to learn about the latest developments in their own spheres of work while also broadening their knowledge of aspects of dentistry they may not know much about.”

Speakers and topics confirmed so far include Dr Chet Trivedy with three sessions – medical emergencies and safeguarding in the core CPD stream, plus oral and neck cancer; dental technician Sean Wilkinson covering the future of immediate loading plus a workshop entitled ‘Implant Planner Workflow’; Dr Marina Harris will look

at the latest developments in periodontology as well as stress and psychological well-being in the dental team; lab owner Andrew Taylor will tackle working with zirconia and suggest ways that dentists can take better impressions; and there’s much more on the way.

Teamwork is urging prospective exhibitors to get in touch early to avoid disappointment – the compact exhibition will feature a central hub and networking area where free refreshments will be available all day; with a hot or cold lunch included for all delegates.

Chris adds: “Part of the appeal of DenTeam is the laidback atmosphere between sessions, when delegates and exhibitors can mingle and discuss the latest developments in dentistry. We believe the best learning experience incorporates the products and services available – the profession and the industry helping each other to provide better dentistry for all.”

The full programme is due to be published in January when the delegate rates will be announced. Early bird rates will be available until April and DTA members will receive a special extra discount. “We’ve made sure to keep costs low for technicians,” Chris says, “because we’re keenly aware of the financial pressures they face. We’re confident in putting together a really useful, worthwhile programme for techs that helps them reach their CPD quotas while offering networking opportunities with dentists from all over the south-west of England and beyond.”

For further information and to register your interest in attending, exhibiting or sponsoring at the event, visit www.denteamcpd.com, email chris@teamworkprofessionals.co.uk or call Chris on 07801 657608.

At only £39.95 per year, for UK residents, this must be the cheapest way of keeping up to date. Help your colleagues to keep up to date as well. Ask them to call the subscriptions Hotline on 01202 586 848 now.
