The PFM has been an industry standard for over 50 years, the full cast even longer. With the emergence and change to digital in all ceramics, many have chosen to stay with analog technology when it comes to PFM and full cast crowns. But with Ceramill Sintron, a digitally designed alloy (cobalt chrome) substructure and full cast is possible. Perry Carroll, CDT, discusses what Ceramill Sintron is, how it’s designed and milled, why it’s an advantage and what can be achieved by using it in your laboratory. He also gives a hands-on demonstration of the material.
