Mounting Evidence for the Efficacy of Direct Posterior Resin
I started placing direct posterior resin restorations instead of amalgam following the introduction of Dentinal Adhesion. Studies by Dr. Gordon Christensen show that the survival rate of the average posterior resin is 7 Years.
I have been photographing my work for the last 25 years and can absolutely show that posterior resins will last at least 22 years without leaking.I am posting this so that Resin Deniers will reconsider the longevity and usefulness of resin.
I have always used a rubber dam to place my resins but only started using a bevel on all cavosurface margins about 16 years ago. This case does not have a bevel and margins are clearly visible but NO leakage on the vertical walls was evident.
