Structure the occlusal surfaces of the upper molars

Abstract

The chewing efficiency of the teeth, the trajectory of move-ments of the lower jaw, the ratio of the jaws of the central and lateral occlusion largely depend on the shape of the chewing surfaces of the molars. Their high-quality restoration will help during dental restora-tions to avoid mistakes associated with impaired occlusal interactions of the jaws, pathological abrasion and a decrease in the occlusal height.
