Morphometric characteristics and correlation relationships of bone structures of TMJ-jaw joint in extending concepts of individually typological variability

Abstract

The structural characteristics of the morphometric characteristics of the bones of the temporomandibular joint were studied on 103 passported sculls of adults, and the patterns of individual typological variability determining the type of its structure were also determined. According to the results of the study, the main dimensional characteristics of the mandibular fossa, articular tubercle and head of the lower jaw were established. Depending on the ratios of the selected parameters, three forms of the head of the lower jaw, seven forms of the mandibular fossa and seven forms of the articular tubercles are distinguished. Of the presented forms, the most common are the medium-wide head of the lower jaw, the medium-deep medium-wide mandibular fossa and the medium-high medium-wide articular tubercle. The results of the study can be claimed by dentist’s orthopedists and orthodontists when planning the treatment of patients with dentoalveolar anomalies and deformities, as well as patients with full adentia.
