GAP Australasian Dentist Sept Oct 2020

Category Australasian Dentist 41 this apart from the often-grainy finish of “bonding” Aesthetic transformation is not a new concept in restorative dentistry. However, the ability to injection over-mold a human toothwith heated multi-viscosity resins in precise matrices with an exquisite gingival seal, and without cutting the tooth to accommodate indirect ceramics is new. The reader is encouraged to learn more online and/or take a hands-on training if interested. u Bioclear is exclusively available from Amalgadent Dental Supplies Call 1800 806 450 for Bioclear product enquiries.

The matrix selection and insertion must be appropriate. The contacts must be lightly sanded to allow insertion of the matrix all the way to the attachment level. 2. A well punched heavy rubber dam using a smaller than usual size for each hole, helps to keep the matrix pressed against the root. 3. A well-matched flowable and creamy paste composite is injected one after the other, like light body and heavy body impression material. 4. Heating of the composite to 155°f (68°C) allows ideal flow. The dramatically lowered viscosity helps to leave the matrix position and apical seal undisturbed. About the author Dr Clark is director of Bioclear Learning Centers International. He founded the Academy of Microscope Enhanced Dentistry, creates curriculum for dental schools, and has lectured in 25 countries. He developed the Bioclear Matrix System for placement of biologically appropriate, aesthetically pleasing direct composite restorations for facilitating Injection Molding of the Clark Class I and Class II preparations, diastema closure and black triangle elimination combined with papilla regeneration. The Clark Class I and Clark Class II preparations and restorations are now being evaluated in seven in vitro studies. He is preparing a long-term clinical outcome study. He owns several US patents. He published the first guide to dentinal and enamel cracks based on clinical microscope dentistry (16X magnification). Figure 17. These images show injection of the heated Filtek Supreme Ultra flowable composite, which will be immediately followed with the heated Filtek Supreme Ultra regular (paste) composite. The complex is then light cured together. The goal is to have 95% of the load bearing and facial areas to be the Filtek paste material, which has a great track record for strength and shine retention. The flowable fills in the nooks and crannies. Figure 18. After the first tooth is injection molded, we shape to 80% and then move to the next tooth. There is no need to put a shield matrix on the teeth that have been injection molded previously Figure 16. The yellow colour-coded small tooth matrices are set in place. The size sequence starts at red, then yellow, green and blue which have been designed to close the smallest to the largest black triangles that we have observed in clinical practice.
