A tremendous amount of R&D money is flowing into the science of synthetic bone type materials with advancements every year. Special milling equipment and technology is required for these systems but we have been involved for several years now with encouraging results. Trinia, Trilor, Tritan, Pekkton, and Solvay are some of the newer brand names you may have heard. We have worked with all of them and it is clear which systems have the most potential. In fact, most of our treatment partials frames are now designed and milled with Solvay’s Ultaire AKP, which has proven to be a reliable and significant upgrade for long term interim treatment.
