Temporomandibular joint (TMJ) changes are quite frequent in adults, but not all changes are degenerative. A high prevalence of bone alterations in the TMJs was reported by different research groups. Disturbed remodeling of bony articulating structures occurs because of overloading masticatory forces or because the mechanical loading in the area out-weighs the adaptive capacity of the TMJ structures. Although most of the degenerative TMJ alterations are identified at the level of the condylar process, a complete evaluation of the degenerative modifications encountered in the temporal TMJ region should not be forgotten as they are important for a comprehensive assessment and further management of the clinical situation. Several research groups have described osseous remodeling in the temporal component of the TMJ. Evidence is scarce for degenerative modifications at the level of the articular eminence and thickening of the roof of the glenoid fossa has been associated with osteoarthritis.
颞下颌关节（TMJ）的变化在成年人中相当常见，但并非所有变化都是退行性的。不同的研究小组报告了 TMJ 中骨改变的高患病率。由于咀嚼力过大或该区域的机械负荷超过 TMJ 结构的适应能力，导致骨连接结构的重塑受到干扰。尽管大多数退行性 TMJ 改变发生在髁突水平，但不应忘记对颞下颌 TMJ 区域遇到的退行性改变进行全面评估，因为这对于全面评估和进一步处理临床情况很重要。几个研究小组已经描述了 TMJ 颞骨部分的骨重塑。在关节突水平的退行性改变的证据很少，而关节结节的增厚与骨关节炎有关。
