With now a few Level One Trainings under my belt, teaching the F.O.C.C. (Fissure Height, Occlusion, Contours, Contacts) concept as a systematic process to design definitely streamlines the chairside approach. But as I also have two new assistants learning the ins and outs of CEREC design, I realized a BIG "O" was missing! When a proposal is first generated, it is automatic that I look at the buccal/lingual corridor, without question, first, so that I am able to position the restoration in the arch to my "ideal" by using the "MOVE" tool or simply, Anatomical 2D. Inevitably, as my assistants and new users waited to position the tooth in the "Contours" Step (previous Step 3), we would almost always have to jump back to the "Occlusion" (previous Step 2) and refine. I thank Kristine Aadland for coming up with the original PDF (which I have edited) showing these steps to help ourselves, our assistants, and new users not to get overwhelmed by the tools and tricks of design. As from here on, I will choose the Big "O" to begin the F.O.C.C approach!
