Differences in skeletal components of temporomandibular joint of an early medieval and contemporary Croatian population obtained by different methods

Factors influencing the articular eminence of the temporomandibular joint (Review)

“…Therefore, the mean values of the AEI were statistically significant lower in medieval skulls ( 11 , 31 ) probably as a consequence of the different masticatory loads determined by the medieval eating habits ( 31 ). However, in another report on 60 human dry skulls specimens, no statistically significant differences regarding the AE (AEI and AEH) were encountered between medieval and contemporary Croatian populations ( 1 ). In addition, another paper reported variations between the African-Americans and European-Americans regarding the angles of the slopes of the AE ( 47 ).…”

“…However, Unal Erzurumlu and Celenk described no statistically significant difference between the AEI values of dentate females and males (23). Moreover, in a 2016 study, no statistically significant differences regarding AEI and AEH were encountered between medieval and contemporary Croatian populations independent of age and sex (1). Additionally, Jasinevicius et al reported in two studies no differences in AE angulation between the sexes (47,52).…”

“…The temporomandibular joint (TMJ), the most complex and evolved joint in humans, is defined by the paired joints that connect the mandible to the skull, while its name is derived from the two bones that form the joint: the temporal bone and the mandible. A multitude of human mandibular movements are possible due to the TMJ, adapting the human being to omnivorous eating and making possible a wide variety of physiological functions: chewing, swallowing, speaking and even facial expression ( 1-3 ). More specific, the TMJ consists of the condylar process of the mandible penetrating into the mandibular fossa of the temporal bone, while the articular disk lays bilaterally between the fossa and the condyle ( 4 , 5 ).…”

Correlação da pneumatização e morfologia do componente temporal da ATM

“…22 Thus, a high mechanical load is transferred to the components of the temporal bone of this system. 8 Since the MACS in the TMJ temporal component represents an area of minimal resistance, 5 we hypothesized that the degree of pneumatization of the temporal component of the joint may affect its morphology. Our hypothesis was also based on our daily CBCT examinations, which suggested that pneumatization would occupy a large area in the TMJ temporal component, indicating some interference with TMJ morphology.…”

“…5,6 As the TMJ is an anatomically and biomechanically complex structure, 7 the morphology of temporal bone is an important element in the biomechanics of the joint and masticatory system that interferes with the distribution of stresses in these regions. 8 The morphologic features of the temporal bone are important for planning surgical procedures in this area. The temporal component of the joint often exhibits a variable pneumatization pattern and morphology, which can be a possible complicating factor in TMJ surgery.…”
