AGE FEATURES OF THE STRUCTURE OF THE LOWER JAW

Abstract

The purpose of the study is to conduct a morphometric examination of the jawbone and to find out its precise informative signs, based on this, to study the signs of the jawbones and the dynamics of age variation of the facial skull with different shapes through the jawbone.
Study the age dynamics of the lower jaw. Materials and methods were selected from 22 lower jaws (fetus, newborns, children, adults) from the collection of the Museum of Osteology of the Department of Human Anatomy and Medical Terminology of the Azerbaijan Medical University. In newborns, the processes of the lower jaw are shirt, wide and square in shape. The articular processes
are located at the level of the alveolar margins. The shape and position of the articular head are individual and depend on the function of the temporo auxiliary – mandibular joint. Increase in the thickness of the articular process depends in most cases on an increase in the size of the base of the skull, to a lefsser extent on the formation of teeth. If you connect the longest dimensions of the head, the
lines should intersect in front of the foramen magnum, forming an angle.
The distance between the processes of the lower Jaw in the fetus is 12 mm, newborns is 16 mm, children is 11-15 mm, adults is 19-30 mm. Between the processes, a notch of the lower jaw is formed. Depth and width of notch are individual. In most cases, width is 30-37 mm, depth is 12-16 mm. Broadjaces have a wider depth. The distance between the noth and the angle of the lower jaw in the fetus is 15 mm, children is 22-24 mm, adults is 36-54 mm.
