颞下颌关节骨性关节炎是一种非炎症性关节炎性疾病，其主要表现为关节结构的退行性改变。本研究的目的是评估骨关节炎患者的颞下颌关节的骨骼形态与严重的骨性错（II类和III类）和患者的I类作为对照。根据颞下颌关节紊乱病的研究诊断标准（RDC/TMD），对45例1类、28例II类和44例III类白人患者的锥形束CT图像进行了髁突和窝/隆起复合体的任何退行性改变的评估。在所有组中，最常见的特征是关节面变平和皮质下硬化。在3%的1类、43%的II类和20%的III类患者关节中观察到对应于骨关节炎诊断的特征组合。总之，退行性颞下颌关节变化更常见于骨骼颌骨差异的患者，但即使在临床相似的错牙合患者中也可以观察到广泛的个体间差异。
Osteoanhritis of the temporomandibular joint (TMJ) can be described as non-inflammatory arthritic condition that results in degenerative changes of the joint structures. The aim of this study was to evaluate the skeletal morphology of the TMJ in patients with osteoarthritis with severe skeletal malocclusions (Class II and Class III) and patients with Class I occlusion as controls. Cone beam computed tomography images of 45 Class 1,28 Class II and 44 Class III joints of Caucasian patients were assessed for the presence of any degenerative changes in the condyle and fossa/eminence complex as described in the research diagnostic criteria for temporomandibular disorders (RDC/TMD). In all groups, the most commonly observed features were articular surface flattening and subcortical sclerosis. A combination of features that corresponds to a diagnosis of osteoarthritis was observed in 3% Class 1,43% Class II and 20% Class III patient joints. In conclusion, degenerative TMJ changes were more common in patients with skeletal jaw discrepancies, but wide inter-individual variations can be observed even in patients with clinically similar malocclusions.
