this case is a few years old, so possible better options available now, but the facial porc is about .2 mm thick in some places and doing a catilever with allceramic is a ?. Some of the Dr's I work with do not like Zirconia. Today I might have used Emax. This has worked so well for us, you know how it is we like what works! I teach some and do some work for UAB, some there do not like zirconia. I like almost every material out there. The problem is technic. I was doing consulting for a lab 2 weeks ago saw 4 veneers being placed the Dr did every thing wrong. It was hard to believe!
