This DVD combines the presentations of the "occlusal compass" and the natural waxing-up technique. The occlusal compass helps technicians to predict and define the natural directional movements of the mandible on the horizontal plane, including protrusion, laterotrusion, and mediotrusion. In addition, the natural waxing-up technique is considered to be one of the most appropriate methods of implementing the occlusal compass to facilitate the modeling of anatomically correct and functional occlusal surfaces of molar teeth. This DVD includes a presentation of the occlusal compass, the applicable anatomy, nomenclature, dental coordinate system, and the waxing-up of all segments of a maxillary molar and an entire quadrant following natural waxing-up technique. A step-by-step demonstration shows how to locate contact points and where spaces must be maintained.
