研究下颌骨不对称性的形态和功能影响，不仅有助于了解咀嚼功能障碍的发生发展过程，而且有助于为循证咬合治疗提供建议。 探讨MA患者颞下颌关节（TMJ）的三维形态及其与髁突不对称运动的关系。根据门顿偏离正中矢状面4 mm，将50例受试者分为MA组和对照组（每组25例）。颞下颌关节形态（髁突，关节窝和颞下颌关节空间）进行了评价，使用三维分析程序。通过计算机轴向成像仪记录和测量髁突的三维运动（从矢状面和水平面）。测量每个参数的侧对侧不对称性。计算非对称指数值，以评估TMJ形态与髁突运动的相关性。对于统计分析，使用Wilcoxon符号秩检验、Mann-Whitney U检验和斯皮尔曼秩相关。与非移位侧和对照组平均值相比，MA组移位侧的关节盂体积、表面积、前后长度和髁突体积显著减小，关节隆起角、关节盂窝和髁突轴角显著增大（P < 0.05）。MA组颞下颌关节间隙两侧无差异，但内侧、上级和前关节间隙较对照组明显变窄（P < 0.05）。髁突路径长度和髁突矢状面倾斜度显著不对称。髁突体积的不对称指数与髁突路径长度的不对称指数显著相关（P = 0.005）。关节窝体积不对称指数和关节隆起角与髁突矢状面倾斜度显著相关（分别为P = 0.009和P = 0.002），关节窝体积不对称指数与双侧髁突横面倾斜度显著相关（分别为P = 0.006和P = 0.016）。颞下颌关节的形态不对称性在移位侧和非移位侧之间存在显著差异，并且与MA患者髁突运动的功能不对称性密切相关。(350/350）。在线版本包含补充材料，可通过10.1186/s40510-022-00445-0获得。
Investigating the morphological and functional effects on mandibular asymmetry (MA) is important not only to understand the developmental process of masticatory dysfunction, but also to provide suggestions for evidence-based occlusal treatment. To evaluate three-dimensional temporomandibular joint (TMJ) morphology and its relationship to asymmetrical condylar movement in MA patients. Fifty subjects were divided into MA and control groups (n = 25 each) according to a menton deviation of 4 mm from the mid-sagittal plane. TMJ morphology (condyle, glenoid fossa and TMJ spaces) were evaluated using a three-dimensional analysis programme. Three-dimensional condylar movements (from the sagittal and horizontal planes) were recorded and measured by computerized axiography on protrusion. Side-to-side asymmetry was measured for each parameter. The asymmetry index value was calculated to assess the correlation between TMJ morphology and condylar movement. For the statistical analysis, Wilcoxon’s signed-ranked test, the Mann–Whitney U test, and Spearman’s rank correlation were used. Glenoid fossa volume, surface area, anteroposterior length, and condylar volume were significantly smaller, and articular eminence angle, glenoid fossa, and condylar axial angle were significantly larger, on the shifted side of the MA group when compared with those on the non-shifted side and the mean values of the control group (P < 0.05). The TMJ spaces of the MA group showed no bilateral difference but were significantly narrower in the medial, superior, and anterior joint spaces when compared with the control group (P < 0.05). Condylar path length and sagittal condylar inclination were significantly asymmetrical. The asymmetry index of the condyle volume was significantly correlated with that of the condylar path length (P = 0.005). The asymmetry index of the glenoid fossa volume and the articular eminence angle were significantly correlated with that of the sagittal condylar inclination (P = 0.009 and P = 0.002, respectively), and the asymmetry index of glenoid fossa volume was significantly correlated with the bilateral transverse condylar inclination (P = 0.006 and P = 0.016, respectively). Morphological asymmetry of the TMJ is significantly different between the shifted and non-shifted sides and is closely related to functional asymmetry of condylar movement in MA patients. (350/350).
