IDEM Singapore coming up on October 7-9

I

t almost seemed like we’d never had a pandemic as Digital Dentistry & Dental Technology 2022 opened on June 3. For all intents and

By Joseph Allbeury purposes, the event unfolded exactly the same as the last staging in 2019. A huge crowd attended to hear a first class 2-day lecture and workshop programme delivered by our amazing line up of 43 speakers, enjoying breaks amongst a healthy trade display. It was bustling, noisy and energetic. It felt right. It felt familiar. And it was fun. But of course it was by no means a fait accompli that it would be like this. Some of the other dental events I’ve been to this year felt a bit “off”. And I don’t mean that in the obvious transitioning-from-a-pandemic sort of way.

And then there were a number of worst case scenarios we planned for - like speakers being unable to attend - that also never happened. And the icing on the cake was that there were no reports of the event being a COVID super-spreader, as had occurred with a dental event earlier in the year, so it ticked every box in every way.

So thank you very much to everyone who came together to help with the staging of one of the largest educational events in Australia... from speakers, to sponsors, to trade exhibitors and everyone who helped... and most especially to the almost 500 delegates who attended. Thank you.

For everyone who did attend and for those who were unable to make it, we’re planning a few spin-off events throughout the rest of the year. And what I mean by that is we’re running some full day programs with some of the speakers from Digital Dentistry & Dental Technology 2022 that will provide greater detail and insight into hot topics.

The first of these is a full day event with Sam Dias on intraoral scanning and digital dentures on September 10 in Sydney. Sam’s sessions at DDDT22 were packed and he is keen to present a more detailed presentation based on how he delivers dentures digitally every day through the four dental practices he owns in Sydney and regional New South Wales. This is a dose of reality from first hand experience so if you’re interested in creating dentures digitally, register now at www.ios.events.

We’re also looking at another full day programme on 3D printing with a selection of speakers from DDDT22 presenting a masterclass - so stay tuned for more details.

A raft of changes have occurred to infection control regulations in Australia from the Dental Board of Australia (July 2022), the new edition of the Australian Dental Association Guidelines and also regarding COVID-19. On September 3, Emer. Prof. Laurie Walsh AO, the doyen of infection control in Australia, will present a one day update of all these changes and more. Register at www.icupdate.au.

Finally, we’re looking for readers to start contributing videos to Dentevents.TV and each month we’re offering a prize for the best video! See page 16 for details.

Stay safe!

Almost 500 delegates attend Digital Dentistry & Dental Technology 2022

T

he third annual Digital Dentistry and Dental Technology conference has been another outstanding success, attracting some 500 delegates to the Novotel Sydney Brighton Beach over two days on June 3 and 4, 2022.

“As the organiser of the event, it was fantastic to see one of the largest dental conferences in Australia play out seamlessly and without a hitch,” said Dentevents’ Joseph Allbeury. “It was like the pandemic had never happened with an enthusiast audience of close to 500, together with 43 stellar local and international speakers and an array of dental industry representatives all enjoying the event.

“Digital Dentistry and Dental Technology is an intimate affair in a hotel setting and it generates a real buzz. You can feel the energy, both in the sessions and during the breaks.

“With COVID-19 now a part of life in Australia, we of course planned for multiple scenarios that could have occurred due to this but as it happened, every speaker attended, every session was delivered and there were no reports post-event of participants becoming ill. It was a fantastic outcome.

“The feedback on all levels was resoundingly positive and we can see exactly where we need to steer the event for 2023 and beyond in order to attract an even larger audience and continue to be at the cutting edge of dental education.”

Digital Dentistry and Dental Technology 2022 presented delegates with a choice of over 90 education sessions - 84 hours of content - in 7 concurrent streams presented by 43 speakers.

Topics covered included 3D printing, intraoral scanning, milling CAD and CAM software, materials, smile design, digital dentures, implantology, CBCT, restorative, aligners, orthodontics and more.

“The success of Digital Dentistry and Dental Technology 2022 is thanks to a lot of help and support from everyone involved,” Mr Allbeury said.

“The event simply could not take place without our sponsors - Ivoclar, Innovatio Dental Supplies and Fabdent. Each of these companies presented an education stream packed with outstanding content and delivered by an amazing group of speakers, several of whom made the journey from overseas.

“The talent on show throughout the entire event in all streams was simply outstanding and included some of Australia and the world’s most sought after speakers.

“As the organiser, I am always trying to ensure the program is relevant and compelling and nothing says that more than a lecture room that is standing room only with still more delegates bulging out the door. This was certainly the case on a number of occasions throughout the event. So thank you to all the speakers who presented throughout the two days of the event.

“Thank you also goes to the dental industry and the 40 companies that participated. And I would also like to thank the NSW Government who supported the event with a Business Events Grant.

“Thank you to Dani, Angus, Michael and Frank who hosted lecture rooms and thank you to my family who I steal time from every year to organise and run the event.

“And finally, thank you to everyone who attended the event as a delegate, many for the third time. Without you, all our hard work would be for nothing. So we hope to see you again in 2023.”

Milestone in the digitisation of dentures: Ceramill Motion 3 New intelligent hybrid milling unit simplifies everyday laboratory work

A

mann Girrbach launches the Ceramill Motion 3, an intelligent hybrid machine which makes fabricating dentures even more convenient and, in particular, more digital. At the same time, users benefit from a wide variety of materials and indications and the accustomed high Amann Girrbach fabrication quality.

The Ceramill Motion 3 is designed for wet and dry operation. The 5-axis milling machine operates completely autonomously and can therefore manufacture unsupervised both during the night or also on weekends when connected to the AG-Live platform. Users have the possibility of accessing the intelligent hybrid machine remotely, to receive orders safely and quickly, as well as to monitor everything related to production and customer service. And above all, the integrated analysis functions allow workflows in the laboratory to be analysed and optimised on an ongoing basis.

Guided CAD/CAM production and maintenance, an intuitive HMI, as well as integrated RFID tools and holders ensure process reliability and facilitate the handling of tools and consumables. Innovative sculpturing technologies (C-Clamp) allow even the finest fissures to be milled into the front surface of the restoration with the Ceramill Motion 3. “With the Ceramill Motion 3, we have developed an intelligent milling unit that meets the high quality demands of our customers. It makes their work easier through digital features and allows for optimal use of resources. The machine thus meets the needs of both the dental technician as well as the laboratory manager and marks a milestone in the digitisation of dentures,” said a delighted Nikolaus Johannson, Head of the Global Business Unit Lab CAD/CAM at Amann Girrbach.

Ceramill Motion 2 DRY upgraded

W

hen launched in 2012, the Ceramill Motion 2 5-axis milling unit redefined the industry standard in terms of technical capabilities, fabrication diversity and quality. On the occasion of its 10th anniversary, a major update was introduced with the new Mark IV generation of machines together with a new package: the DRY Package for dry milling.

The Ceramill Motion 2 was one of the first milling machines which could be used dry or wet. This shifted the value creation chain back to the laboratories. Worldwide, this generation of machines has clocked up over 10 million operating hours, making it the most successful upgradeable hybrid platform of all time. This is also confirmed by enthusiastic customer testimonials, such as that of Benjamin Votteler from Dentaltechnik Votteler GmbH & Co. KG: “My Ceramill Motion 5x DNA works just like me: precise, fast, aesthetic, versatile.”

To mark this success story, a major machine update has now been implemented and the Ceramill Motion 2 DRY has been upgraded with innovative milling strategies and a new, open C-Clamp blank holder. “The Ceramill Motion 2 DRY continues to represent the benchmark in terms of fabrication quality. The update enables laboratories to work even more efficiently, accurately and faster. Above all, the package impresses with its excellent price-performance ratio,” said Nikolaus Johannson, Head of the Global Business Unit Lab CAD/CAM at Amann Girrbach. In addition to the DRY Package, two further anniversary packages are available: the HYBRID Package, which allows both wet and dry processing, and the CAPACITY Package, consisting of two milling units.

Thanks to state-of-the-art digital workflows that combine scanning of impressions, fabrication planning, design and automated production processes, many process steps are now becoming more commercially viable, heralding the transformation of dental laboratories and dental practices. As one of the world’s leading manufacturers of integrated solutions for high-quality dental applications, Ivoclar enables a simple and straightforward introduction to innovative dental fabrication processes with a comprehensive product and system portfolio for dentists and dental technicians. The digital workflows combine almost 100 years of Ivoclar experience in the dental industry with leading-edge technology, premium-grade materials and harmonised workflows – meaning greater flexibility, profitability and efficiency in the daily routine for dentists, dental technicians and dental laboratories.

Digital workflows: the future of dentistry! entistry is as individual as a patient’s anatomy. No two cases are the same and every treatment is specifically tailored thanks to a longstanding tradition of craftsmanship that puts the patient first. Just like any other craft, the quality of the final result depends on a number of factors such as the material, experience, planning and precision during implementation. Creating superior quality dentures that are also cost-effective to fabricate and eliminate as many potential defects as possible is always a challenge. Now, thanks to digital dental technology, risks and uncertainties can be mitigated, enabling outstanding precision, accuracy and efficiency throughout all phases of the workflow while also improving process

Zolid zirconia - as successful as ever In 2022, Amann Girrbach will be celebrating two anniversaries at once: 15 years of zirconia production at the Austrian site and 10 years of Zolid

A

mann Girrbach, one of the leading manufacturers in the field of zirconia, is celebrating two important anniversaries this year: 15 years ago, the company produced zirconia blocks for the fabrication of dentures for the first time and exactly ten years ago, the globally successful Zolid brand was launched.

Customers will therefore receive a tenyear warranty on all Zolid materials as of now. At the same time, Amann Girrbach will be hosting various webinars on zirconia throughout the year under the hashtag #nosurprisezirconia.

Amann Girrbach was one of the first companies to start manufacturing zirconia for dentures 15 years ago. Due to the rising demand for increasingly aesthetic zirconias and the desire for more cost-effectiveness

18 eLABORATE

and process reliability, Amann Girrbach introduced the Zolid brand five years later. With Zolid, CAD/CAM blanks that achieved high aesthetics without requiring complex veneering processes were available to users for the first time.

Since then, the company has been continuously developing the corresponding materials and processing methods: meanwhile, blanks such as the Zolid Gen-X allow for lifelike restorations with integrated colour gradients in 16 Vita shades.

In addition to the excellent aesthetic properties and outstanding mechanical values, they prove convincing due to their diversity of indications and their clinical long-term success. In the context of quality assurance, only the best raw materials are processed here using the strictest test methods and certified processes. To give an example, Amann Girrbach is one of the first dental companies to be certi-

fied in accordance with the new Medical Device Regulation, thus supporting users in complying with MDR obligations.

“This year we are celebrating two special anniversaries that once again demonstrate that we at Amann Girrbach are constantly driving the boundaries of technical possibilities forwards,” said a delighted Melanie Röschmann, Director Global Business Unit - Consumables at Amann Girrbach. “At the same time, we are taking this opportunity to underline our quality promise with a 10-year warranty on all Zolid materials. We view ourselves as an holistic system provider and support our customers along the entire customer journey. With this in mind, we will also be focusing more on training and education in the coming years with regard to zirconia. This year, we will be kicking off with a series of webinars on the subject of working with zirconia.”

n dentistry, communication is a three-way information exchange between the patient, dentist and laboratory, all focused on a single goal—successfully meeting the patient’s expectations. In theory, the more information each party imparts to the next, the more certain and optimal the outcome, especially in highly aesthetic cases. In an analogue information exchange, the patient verbally expresses his or her concerns and desires to the dentist. The dentist listens intently to the patient’s concerns and expectations, envisions what the outcome of the case should look like and then writes a prescription, or may even call the laboratory,

detailing the case and expected outcome. It’s up to the laboratory to interpret all the collected information and fabricate a restoration that it believes meets the expectations of both the dentist and patient, often without ever seeing the patient. It is not until the seating appointment that the three parties—patient, dentist and laboratory—discover whether or not the information exchange and envisioned outcome has resulted in the restorative reality the patient expected. This fragile hundreds-year-old information exchange can be upended by any number of missteps in the communication process, from a bad impression and inaccurate shade interpretation to the selection of restorative materials and subjective decision-making.

Double Screw Bar: New technique for the production of full-arch prosthetics on divergent implants

Figure 1. The set-up revealed strong divergence of the implants towards the vestibular area, which would affect the general aesthetic of the final restoration due to the well visible screw channels in the anterior area.

T

he production of full-arch prosthetics on divergent implants is one of the most challenging jobs for the techno-clinical team. However, with the new Double Screw Metal technique it is now possible to produce highly stable and precise bar-supported rehabilitations even in complex cases without compromising the full arch aesthetics. Then, the integration of this new technique not only avoids non-aesthetic vestibular channels, but also improves post-operative maintenance and hygiene.

In the current case, a patient presented with complete maxillary edentulism and severe left bone atrophy in the upper jaw.

The virtual tooth set-up revealed a strong divergence of implants towards the vestibular area. To strike a balance between function, stability and aesthetics in the final restoration, a primary bar was integrated using the Double Screw Metal technique.

The planned restoration consisted of a titanium bar and a secondary structure in Prettau® 2 Dispersive® zirconia. The design of the primary structure incorporated an innovative CAD/CAM workflow in which four additional screws were integrated to screw the secondary structure to the bar. The virtual position of the screws was visualised using the new Double Screw Metal function of the Zirkonzahn.Modellier design software (Attachment module), which allows the generation of virtual

As today’s patients become more informed, discerning and demanding, ever greater pressure is being placed on the dental team to meet their restorative objectives. Fortunately, digital dentistry has emerged to provide tools that not only reduce the subjective human element in the communication process and peopledriven workflows, but that also empower the patient in the critical aesthetic decision-making process.

From intraoral scanners and CAD/ CAM production to powerful software that allows the patient to preview and approve the proposed final case outcome, the digital approach to the information exchange, workflow and final outcome offers the patient, dentist and laboratory a more predictable, accurate and efficient pathway to meet their envisioned expectations.

Figure 1. Preoperative view of retracted anterior arch. The patient did not like the appearance of the 10-year-old all-ceramic crown on tooth 11 and the white spots on teeth 12, 13, 22 and 23. There was also a chipped incisal edge on tooth 21, as well as cervical concavities on the mesial and distal aspects of the tooth.

Case report healthy female in her mid-20s presented to the practice concerned about the shade and shape of a crown that had been placed 10 years earlier on tooth 11, the cervical contours of tooth No. 21 and white discolorations on teeth Nos. 12, 13, 11 and 23, which made her self-conscious about her smile (Figure 1 and Figure 2).

She was studying for her law bar exam and before venturing into the workplace, she wanted to improve the aesthetics of her smile.

At the consultation appointment, the clinician also noted the cervical concavities causing a black triangle between teeth 11 and 21, as well as the gingival height discrepancy between the teeth. Tooth 21 also exhibited a chip on the incisal edge.

Although the patient wanted to restore all six teeth, the clinician advised that the white spots noted on the four teeth could be treated without destroying any tooth structure and recommended restorations for teeth 11 and 21, along with crown lengthening for tooth 11. The patient agreed and was scheduled for a recordstaking appointment.

Figure 2. Preoperative retracted left view demonstrates the high chroma on the cervical third of the natural teeth and moderate translucency on the incisal third.

Restoring single centrals that blend seamlessly with adjacent teeth, while taking into consideration lip dynamics, is one of the most difficult challenges in dentistry and requires the dentist and laboratory to have a shared vision for the final case outcome.

At the next appointment, x-rays were taken, along with a series of photographs, following the protocol set by the laboratory for highly aesthetic cases. The upper arch was scanned using an intraoral scanner (iTero, Align Technologies), capturing the length and width of the natural teeth and the occlusal surfaces of both arches for communication with the laboratory. The intraoral scans and the series of photographs were uploaded to the laboratory for a case design proposal.

An online TeamViewer meeting was scheduled for the dentist and technician to discuss the case and view the proposed shared vision of the case design.

The virtual case design was shared with the dentist for 3D analysis (Figure 4), including virtual simulation of chewing motions, a cross-sectional analysis of the proposed design for determination of final material thickness and preparation design and the inclusion of a wing-tipped pontic at the gingival interface to close the black triangle between teeth 11 and 21. Once the design had been approved by the dentist, the digital case design file was shared via video conference with the patient for her input and approval.

A photo was taken with shade tabs next to the natural teeth to ensure the final restorations would blend seamlessly with adjacent dentition, as well as to communicate the darker preparation shade of tooth 11, which would impact restorative material selection for the case (Figure 5). The photo of the preparations with shade tabs was uploaded to the laboratory for restorative material consideration and fabrication. The dentist used the laboratoryfabricated silicone putty matrix to create provisional restorations (Luxatemp, DMG). Multiple photos and an intraoral scan of the

patient with seated temporaries were uploaded to the laboratory for finalising the design and fabricating the final restorations.

Because of the darker preparation shade of tooth 11 and the high translucency on the incisal edge of the patient’s natural teeth, it was important that the final crowns were fabricated with a zirconia material that was highly aesthetic yet would mimic translucency on the incisal edges and blend seamlessly with the natural teeth once seated (IPS e.max ZirCAD Prime Esthetic, Ivoclar).

The final full-contour restorations were milled (ProgaMill PM7, Ivoclar) (Figure 6 and Figure 7). Prior to sintering, the surface anatomy of the restorations was finalised and internal stains (IPS e.max ZirCAD Coloring Liquid, Ivoclar) added to further mimic incisal translucency (Figure 8). Once sintered, the final crowns were stain and glazed (IPS Ivocolor, Ivoclar), final fired and delivered to the practice (Figure 9 and Figure 10).

The clinician removed the temporaries and air abraded the preparations (PrepStart, Danville Materials) to remove any remaining particles of cement or debris prior to try-in of the final restorations. The preparations were rinsed and dried and the crowns tried in using a water-soluble try-in paste (Variolink Esthetic Neutral, Ivoclar) for patient approval of the final restorations. The aesthetics of the restorations were analysed by the patient and dentist in natural light for final approval.

For final cementation, a rubber dam was clamped in place (Nic Tone, MDC Dental) for moisture control and to ensure complete isolation (Figure 11). Each crown was rinsed and a cleaning agent (Ivoclean, Ivoclar) applied into each restoration for 20 seconds, rinsed and dried.

A primer was applied to each preparation (Monobond Plus, Ivoclar) and a cement applied to each crown (IPS e.max ZirCAD, Ivoclar), the crowns seated and light cured. The patient was thrilled with her new smile (Figures 12 through 14) and

38 eLABORATE

Figure 9. Basal view of the final restoration. The bar was anodised in gold to increase the final restoration’s biocompatibility and aesthetic, reducing the grey scale value.

Compared to conventional ceramics, Fresco pastes remain moist for a longer time and can be modelled for several hours. The consistency of the pastes can be further personalised by adding the two mixing liquids Fresco Liquid and Fresco Gel, depending on the preferred working method. Due to their high primary density, the pastes exhibit very low shrinkage. This means that one Fresco firing cycle is sufficient to finish the tooth shape and the gingiva after the first firing. With this firing process, zirconia structures of different sizes can be fired simultaneously. No parameters such as holding time and/or temperature need to be changed: heating and cooling rates are the only ones to be adapted, since they are directly related to the size and mass of the zirconia structure.

If a correction firing has to be carried out, this can be done with the same parameters – this means that with a very simple but efficient firing process stable results can be achieved.

thermoforming | TECHNIQUES

4 products for easier thermoforming

By Peter Herring, Adv Dip Dent Tech, ACCDP

Automated forming hile the idea of saving a few minutes of time may not initially seem important, it’s these elusive micro chunks of time that rapidly accumulate and become a substantial cost.

It’s simple to model out our time savings with an automated system. Take an example of 6 foils thermoformed per day with an average 3 minutes each cycle. Over a month this equates to more than 6 hours or almost a full day of our time that we will spend attending a manual machine through its heating cycle and manually forming and this is not even a high volume scenario.

Automated thermoforming equates to real savings but it is more than just the time saved, automation relieves us from a repetitious task that takes up both our energy and attention in the workplace.

W

Erkodur-al here has been an avalanche of retainer and aligner materials coming to the market recently but Erkodur-al, a relative of the time tested Erkodur, has a combination of economy, durability, clarity, ease of forming and ease of finishing that is unbeatable.

With a more favourable force-loss curve than most known materials, even multilayer materials at up to twice the price do not show better force curve properties compared to Erkodur-al.

T

Special scissors - XL hese curved, serrated scissors are used to trim all soft thermoforming materials and hard foils up to 1.0 mm thickness.

Replacing the previous version, the Special scissors-XL have the same curved and serrated blades as before but with an elongated shank and ring type finger holes.

The improved design gives more leverage and keeps fingers away from the foil edges, making appliance trimming much easier.

Take-off pliers emoving the thermoforming foil from the model is often tedious but the redesigned, slimmer, all-metal reverse action Take-off pliers can help.

Rather than cutting the appliance from the model with burs and discs or attempting to pry off with instruments, the Take-off pliers let you move around the model and gently lever the forming upwards. This results in less stress and reduced chance of damage to the model.w

R

Take-off pliers redesigned in all metal for eased removal of the thermoforming from the model.
