Category 82 AustrAlAsiAn Dentist STEP 8 Tooth removal and injection of the dentine shade acrylic (Vertys Templus Monomassa) For convenience in this case we chose to inject the pink acrylic first, including the full tooth morphology. Following this the teeth were removed and the dentine acrylic was injected. However, it is also possible to inject using the dentine acrylic from the start. the first step was to carefully gauge out the teeth, leaving hollowed- out sockets for the dentine acrylic teeth. Preparing the injection channels A cut is made in the entrance of the sprue to aide the flow of the acrylic into the mould. The pink acrylic denture base was then fitted in the transfer and placed in the flask (Furbo). The injection syringe was filled with the dentine acrylic, ensuring that no air got trapped in the syringe. The flask was injected and cured following the same procedure as for the original dentures. STEP 9 Deflasking and finishing the duplicate dentures the denture was deflasked. it required few adjustments, and finishing was fast. the initial occlusion was also respected. Acrylics for duplicate dentures Templus Monomassa Acrylics (dentine +) Prothesis Excel (gingival acrylic) Vertysystem is a flexible system. Generally labs start off using in for removable cases, before discovering its numerous possibilities for C&B cases. Plaster is no longer required for flasking meaning that there is far less dust in the lab environment. Reduced finishing also means there is less acrylic dust. To benefit from the advantages of the system, organisation and precision are required, and the procedure must be followed carefully. Our lab has moved over to ‘Lean Manufacturing’ since we started working with Vertys; that is to say, cleaner, faster work with less waste. Results Our aim was to use the Vertysystem to fabricate a full upper and lower denture and a second, duplicate denture. in the photos on the next page, you can see the results for yourself. We used the same silicone mould for the original and the duplicate dentures. using the same model and mould set, it is possible to reproduce several identical copies of the initial restoration. the time taken will depend upon the case in hand and the desired results and finishing. Our objective was to reproduce an identical denture. this Vertysystem technique saves time, thanks to the use of silicone rather than plaster materials. the acrylic used had good physical properties and was easy to finish, offering pleasing aesthetic results. Conclusion the aim of this article was not to provide a work tutorial, but to show one of the numerous possibilities this innovate system has to offer, via a clinical case. Although still fairly unknown in the uK and north America, the system has been in use for several years in italy. this system offers numerous innovative possibilities all of which are in the best interests of the patient. it opens up new options that can be proposed to your dentist clients, both for C&B and removables cases, whilst improving cleanliness, simplicity, precision, time saving, and productivity in the lab. u Conclusion Primary denture Primary denture in the mouth Duplicate denture Duplicate denture in the mouth lInICal Imported by 3 DELTA DENTAL Supplies 3deltadental.com.au • info@3deltadelta.com • Ph :+61 0478731344
