Stamping the Occlusal Anatomy, Restoring Posterior Teeth

16 Feb 2014 - 9891

Clinical case of restoration of teeth in two different techniques. For restoration of tooth 37 a silicone key was used. Tooth 36 was restored in a traditional technique. All work was carried out under control by a microscope.
