TMJ osteoarthritis/osteoarthrosis and dentofacial morphology in Japanese females

Relationship of TMJ osteoarthritis / osteoarthrosis to head posture and dentofacial morphology

“…For the linear measurements, they had significantly shorter posterior facial height. These characteristics are in agreement with our pilot study (52) and might lead to Class II skeletal relationships with posteriorly rotated mandibles. A large gonial angle may also be associated with a skeletal open bite tendency.…”

Relationship between the unilateral TMJ osteoarthritis/osteoarthrosis, mandibular asymmetry and the EMG activity of the masticatory muscles: a retrospective study

“…Matsumoto et al. (2) also reported that subjects with temporomandibular joint (TMJ) osteoarthritis/osteoarthrosis (OA) had a smaller and significantly more posteriorly rotated mandible in comparison with normal subjects. Goto et al.…”

Temporomandibular Disorder Signs, Occlusal Support, and Craniofacial Structure Changes Among the Elderly Vietnamese

“…In our sample, those with TMJ tenderness had shorter total mandibular length, which could be explained by the fact that TMJ tenderness may result in ankylosis and inhibit mandibular movement in a clockwise direction. This finding is reinforced by the studies of Ahn et al [11] and Matsumoto et al [14] who wrote that TMD patients had a relatively shorter mandibular and progressive mandibular retrusion.…”

“…Other investigations have used magnetic resonance imaging (MRI) and cone beam computerized tomography (CBCT) to observe changes to the structures of the temporomandibular joint; however, the high exposure to radioactivity and cost of these methods are disadvantages of these methods compared to cephalography. Cephalography has been recognized as a supporting tool for craniofacial morphology analysis of TMD patients [11][12][13][14][15][16]. Emshoff et al [13] found accordance between cephalometric and MRI analysis of TMJ structural characteristics.…”
