In this third part of our series on preparing teeth for anterior porcelain veneers I want to continue the discussion on interproximal design. Int he last video we looked at the treatment planning and clinical design parameters that drive whether we prep through the existing contact or stop our margin labial to the contact. In this video, let's look at the actual prep design, where to place your margins, two different designs to interproximal prep and how to avoid creating line of draw issues.
