PECULIARITIES OF THE ALVEOLAR AND BASAL ARCHES SHAPE OF THE UPPER JAW AND THEIR CORRELATION IN INDIVIDUALS OF DIFFERENT SEX

Abstract

With the aim to study possible variants of the alveolar and basal arches shape of the upper jaw and regulations of their correlation 55 individuals (27 men and 28 women) at the age of 21-60 with preserved teeth row were examined during planned dental examination. All the examined were patients of the “Dr. Dakhno Dental Clinic” (Kyiv). Computed tomography of all these patients according to medical indications was performed with parallel scanning of the occlusive plane. Image reconstruction was conducted with the use of highly resolving capacity bone algorithm. Alveolar and basal arch form of the upper jaw were determined on the images. It was established that alveolar and basal arches of the upper jaw can have a form of five geometrical figures: oval, semicircle, ellipse, trapeze or square. The shape of the alveolar and basal arches of the upper jaw was determined on the images. Alveolar and basal arches of the upper jaw were found to be in the shape of five geometrical figure: oval, semicircle, elliptic, square and trapeze. At the same time, the shapes of the alveolar and basal arches can coincide or be combined in different combinations. Peculiarities of the alveolar and basal arches shapes of both men and women are characterized by pronounced individual variability. Their understanding will enable to avoid a number of complications during dental prosthesis connected with the pressure redistribution on the osseous tissue of the jaws during articulation.
