In this study we aim to describe the three-dimensional analysis of condylar deformation of the temporomandibular joint (TMJ) and morphological changes of the craniofacial jaw in patients with idiopathic condylar resorption (ICR). We also compare those with a control group that is healthy and matched for age and gender. Cone-beam computed tomography (CBCT) and cephalometric radiograph (X-ray) were conducted and analysis of craniofacial measurement, condylar width, length, height, and condylar axial angle changes were done three-dimensionally using ProPlan CMF™ 3.0 software (Materialise). The craniofacial jaw measurements of the ICR patients were significantly different than the control group and the significant changes in the mandible can be seen in ICR patients according to the results of this study. The results of smaller condylar width and height in the ICR group reflect the smaller size of the condyle compared with an unaffected condyle. Also, both right and left sagittal condylar angles (p = 0.001 and p = 0.003), respectively, and axial condylar angles (p = 0.01 and p = 0.02), respectively, displayed significant differences between the two groups. In conclusion, the vertical development of the condyle decreased along with reduced measurements in the width and height of the condyle in ICR patients, and differences in the morphology of the craniofacial jaw and condylar angles were observed between study groups.
在这项研究中，我们旨在描述颞下颌关节（TMJ）髁突变形的三维分析和特发性髁突吸收（ICR）患者的颅颌面颌形态变化。我们还将这些与年龄和性别匹配的健康对照组进行比较。进行了锥形束计算机断层扫描（CBCT）和头颅侧位片（X 射线），并使用 ProPlan CMF™ 3.0 软件（Materialise）对颅颌面测量、髁突宽度、长度、高度和髁突轴向角度变化进行了三维分析。ICR 患者的颅颌面颌测量值与对照组有显著差异，根据本研究结果，ICR 患者的下颌有明显变化。ICR 组髁突宽度和高度较小的结果反映了与未受影响的髁突相比，髁突较小。此外，右侧和左侧矢状状髁突角（p=0.001 和 p=0.003）以及轴向髁突角（p=0.01 和 p=0.02）在两组之间均有显著差异。总之，ICR 患者的髁突垂直发育随着髁突宽度和高度的测量值降低而降低，并且在研究组之间观察到颅颌面颌形态和髁突角度的差异。
