Structural arrangement of the temporomandibular joint in view of the constitutional anatomy

Based on the data obtained through panoramic roentgenograms, cone beam computed tomograms from 297 people featuring various somatotypes, orthognathic bite, and no sign of dentoalveolar pathology, we identified the morphometric parameters for the temporal bone mandibular (articular) fossa, and for th...

Temporomandibular joint Physiological occlusion Сone beam computed tomography Constitutional anatomy Individual typological variability Based on the data obtained through panoramic roentgenograms, cone beam computed tomograms from 297 people featuring various somatotypes, orthognathic bite, and no sign of dentoalveolar pathology, we identified the morphometric parameters for the temporal bone mandibular (articular) fossa, and for the lower jaw head, followed with calculation of index values and the temporomandibular joint temporal congruent index. Depending on the linear and index values of the articular fossa, the patients were diagnosed with a brachio-, meso- and dolichotemporal type of the temporomandibular joint. The articular fossa index value (48.59 +/- 1.82%) of the mesotemporal type indicates a double prevalence of the anterio-posterior parameter over the vertical one; a decrease in the index down to 35.29 +/- 1.74% for the brachytemporal type means a more significant reduction in the articular fossa vertical size (long and low); an increase in the index up to 56.65 +/- 2.12% of the dolichotemporal type points at an increase in the articular fossa vertical parameters (short and high). Regardless of the articular fossa type, in case of the orthognathic bite, the lower jaw head has been proven to occupy no more than 56.33% of the temporomandibular joint volume, evidence to that being the congruency index value. Analysis of constitutional types suggests the predominance of patients with the asthenic type of physique (56.6 +/- 4.3%) over those with a normosthenic (27.3% + 2.9%) and a hypersthenic ones (16.1 +/- 2.3%).
