Interesting Aspect of Partial Frameworks Sourced by Tony Griffin By using a dental surveyor, a model can be tilted in different angles to determine the best path of insertion for a removable partial denture (RPD). An undercut can be a useful and desirable feature for engaging the tip of a clasp to provide retention. Undesirable undercuts are those not used for retention whether on soft tissue overlying the alveolar bone or on hard tooth tissue. Standards for Dental Professionals: Aim: ● To consider how partial denture design can assist in retention
CPD Outcome(s): (i) To review the positioning of clasp tips via use of undercut gauges (ii) To be aware of how the choice of material affects the depth of undercut used (iii) To be aware of how one example of a digital design system enables the dental technician to create a partial denture pattern
Development outcome: C

hen surveying a model, we tend to look for a path of insertion that reduces the actual amount of undesirable undercut, thus reducing the need to block out too much undercut. e.g. a Kennedy Class I (bilateral free-end saddles) with the 11, 12, 13, 14, and 21, 22, 23, 24 standing. If a model is slightly tilted down in the anterior region by tilting the surveyor table, the undesirable undercut on the distal of the premolars can be reduced and engaged by the hard denture base. This assists in retaining the RPD because the denture fits close to the distal side of the premolars. The desirable undercut is then sought in which to place the flexible tip of the clasp. The amount of undercut engaged by the flexible tip depends on the type of material (gold wire, stainless steel wire, etc.) and its structure (i.e. wrought wire, cast metal or flexible plastic) being used for the clasp. Careful engagement of the retentive arm clasp tip into the correct depth of undercut can only be determined by using undercut gauges on the surveyor at the chosen path of insertion. The standard undercut gauge is a rod of metal similar to a bur shank with a

raised area or lip of varying small areas representing the normal three main undercut gauge sizes (as shown in Fig. 1). The normal undercut size ranges are 0.010 inch/0.25 mm, 0.020 inch/0.50 mm or 0.030 inch/0.75 mm. The presenter introduces a selection of clasps e.g. the i-bar and half T, and there is even reference to an extra coronal precision attachment used for retention of a partial denture.

Interesting Aspect of Partial Frameworks... continued... ...you will notice the presenter suggests using a flexible wrought clasp soldered to a cast metal cobalt chromium framework or embedded in a plastic temporary denture; the clasp tip is engaged to a specific depth of undercut. Due to the amount of undercut engaged by a more rigid material, such as cast cobalt chromium, it would be normal to expect to place the clasp tip into less undercut. Indeed, various authorities link clasp material to undercut size. Accurate placement of the
retentive clasp tip to the appropriate undercut depth means the tooth is not traumatised during the insertion or removal of the denture. On the opposite side of the retentive clasp there is either a plate or another clasp. The clasp that is opposite the retentive clasp is called a bracing arm or clasp. The bracing clasp sits above the survey line and does not normally engage an undercut. In this second publicly accessible, five-minute video link, you will be able to see how digital
pattern construction is used to create the shape of a partial for a Kennedy Class III case. ■ https://www.youtube.com/ watch?v=U8A1-6VCu2Q See how the size and positioning of the major connectors (e.g. lingual bar), the minor connectors that attach the clasps and the position of the retentive tip of the clasps can be accurately placed on the VDU screen.

An ideal alternative to explore Ultaire™ AKP is a new high performance polymer that has been custom developed by Solvay Dental 360™ specifically for the fabrication of removable partial denture (RPD) frames. Speaking from Hughes Dental Laboratory in Harrogate, owner and CDT Jonathan Hughes, provided his professional opinion of the material: ‘Ultaire™ AKP is a very versatile material that offers a viable alternative to metal. It enables us to engage to deeper undercuts, which is ideal for lingually inclined dentition and it can provide an ideal solution for tricky cases, particularly where other prostheses have failed in the past. ‘For technicians, Ultaire™ AKP is a much cleaner material to work with compared to cobalt/chrome and flexible materials. It is also easy to trim, and when designed correctly, takes very little time to fit down.

RPD framework for patients. In addition, Ultaire™ AKP is also much nicer to occlude against compared to metal backings, and according to the feedback I have received, the sensation is preferable to chrome on the mucosa. ‘Technicians may not be used to seeing Ultaire™ AKP used routinely just yet, but this does not mean that we should not explore the numerous design concepts it enables, experiment a bit and use the material to our advantage.’ ● For more information about Solvay Dental 360™, Ultaire™ AKP and Dentivera™ milling discs, please visit www.solvaydental360.com
‘Ultaire™ AKP has an elastic modulus of 3500 MPa and a flexural strength of 148 MPa, which means that it is resistant to deformation and provides a strong, stable and retentive

The Art of Immediate Dentures A one-day master class with lectures and a live demonstration on a patient. Presented by Dr Finlay Sutton Friday 6 July 2018 in Garstang Suitable for dentists, CDTs & dental technicians With 7 hours of verifiable CPD Immediate dentures are often some of the most difficult and least well tolerated dentures that we give our patients. I want to share with you the techniques and methods Rowan Garstang (my dental technician) and I use to achieve predictable results with immediate dentures.
I will demonstrate how I make superb impressions – even with mobile teeth in the way. The process from diagnosis, treatment planning and treatment provision will be shown in detail. This will be full of tips, techniques and practical advice that can be implemented straightaway into practice.

YOUR ONGOING GUIDE TO ECPD COUNTING DOWN TO AUGUST LAUNCH What is ECPD? 1. Enhanced Continuing Professional Development (ECPD) is an enhanced version of the CPD. 2. What are the main changes from the current CPD? There are five important changes: ● Less CPD hours because of the removal of non-verifiable CPD ● You MUST make an annual declaration of CPD hours completed ● You MUST have a personal development plan (PDP) and log of activity ● You MUST align CPD activity with the GDC’s ‘new’ development outcomes ● You MUST plan CPD activity according to your own ‘field(s) of practice’ 3. CPD hours you must put in: ● For dental technicians the minimum per 5-year CPD cycle is 50 hours ● For clinical dental technicians the minimum per 5-year CPD cycle is 75 hours To encourage you to do regular activity, there will be a minimum of 10 hours CPD for every two consecutive CPD years.
When does ECPD begin? 1 August 2018 for you and other DCPs.
What should a personal development plan (PDP) look like and what is an activity log? You can design your own personal development plan (PDP) and activity log or use templates designed by the GDC. See... ● PDP: https://www.gdc-uk.org/api/ files/PDP%20blank%20template %20FINAL.docx
● Activity Log: https://www.gdc-uk.org/api/ files/Activity%20log%20blank%20 template%20FINAL.docx
What are the GDC’s new development outcomes? The Standards for the Dental Team set out the ethical principles of dental practice and form the basis of CPD planning and activity through four development outcomes. From August 2018, you will need to map each of your activities to at least one development outcome. As before, there is a list of recommended topics:
articles chosen to ensure you fulfil your CPD and personal learning needs in a new, larger 40-page quarterly format means you can plan how to complete your annual 10 hours of quality CPD. DTA will be announcing a range of additional support options for our members, so watch out for more details at www.dta-uk.org.
● Medical emergencies ● Disinfection & decontamination ● Materials & equipment (dental technicians) ● Legal & ethical issues ● Complaints handling ● Oral cancer: early detection ● Safeguarding children and young people ● Safeguarding vulnerable adults
