To evaluate the relationship between internal derangement and morphological features of the temporomandibular joint by comparing joint morphology between patients with ID and control patients.
The current study prospectively is evaluated the cone-beam computed images of 106 ID patients and 122 patients with asymptomatic joints; recorded angular and linear measurements. The relationships between these measurements and ID are investigated; the differences between the two groups using paired t tests.
There were significant differences in the values of articular slope and the condyle height/glenoid fossa depth (CH/GFD) ratio between patients in the ID and control groups (p < 0.05). There was also a relationship between these parameters and the gender of patients with ID. The condylar position was posterior in the ID group.
Posteriorly and superiorly located condyles with an increased CH/GFD ratio, condyles located eccentrically, and a steeper posterior slope may be risk factors for ID.
通过比较内部紊乱（ID）患者与对照患者的关节形态，评估颞下颌关节内部紊乱与形态特征之间的关系。
本研究前瞻性地评估了106例ID患者和122例无症状关节患者的锥形束计算机图像；记录角度和线性测量值。研究这些测量值与ID之间的关系；使用配对t检验比较两组之间的差异。
ID组和对照组患者的关节斜率值以及髁突高度/关节窝深度（CH/GFD）比值存在显著差异（p < 0.05）。这些参数与ID患者的性别之间也存在关系。ID组的髁突位置靠后。
CH/GFD比值增加、髁突位置偏心且后斜率更陡的位于后方和上方的髁突可能是ID的危险因素。
