As CAD/CAM technology continues to grow, basic knowledge must continue to be incorporated within these newer techniques. Occlusion is still the most important aspect of dentistry and technicians must understand its functional parameters while incorporating them into their technical processes. Peter Pizzi, CDT, MDT, covers how to do this, as well as other topics including the understanding of occlusal concepts, proper substructure to support occlusal concept and the importance of articulation in a CAD occlusion world.
