The structure of the occlusal surfaces of the upper molars

Abstract

The chewing efficiency of the teeth, the trajectory of movements 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 restorations to avoid mistakes associated with impaired occlusal interactions of the jaws, pathological abrasion and a decrease in the occlusal height. The purpose of our work was to investigate, according to the data of domestic and foreign literature, the structural features of the chewing surfaces of the molars of the upper jaw. The molars of the upper jaw are large enough. They gradually decrease in size from the first to the third molar. On a rather large occlusal surface, they have 4-5 tubercles.
