ASSESSMENT OF MORPHOMETRIC INDICATORS OF WISDOM TEETH

Abstract

The purpose of the study is to conduct a comparative assessment of the morphological parameters of the upper jaw during normal eruption of wisdom teeth and their retention. Using standard craniological instruments, the parameters of the upper jaw were measured by dividing the skulls of 80 adults into 4 groups: 1st - with erupted third molars; 2nd - without the base of wisdom teeth; 3rd - with unilateral preservation of the upper third molars and 4th - bilateral retention. According to its morphological measurement parameters, it was found that the upper jaw with bilateral retention is as close as possible to the upper jaw, which lacks the base of wisdom teeth, and the upper jaw with unilateral retention is located on the upper jaw with fully erupted third molars. It was found that the length of the alveolar arch, the distance between the ducts, the distance between the prosthesis and the base and the distance from the incisors to the large palatine opening were significant in the studied groups. Along with this, with difficult eruption of 3 molars, a decrease in the parameters of the bone palate is shown, as well as the presence of differences in the structure of the gnatic part of the face associated with a more distal position of the upper jaw during retention. Complete and timely eruption of wisdom teeth has a significant impact not only on the growth of the upper jaw, but also on the vertical profile of the face
