摘要:

目的 研究骨性Ⅰ类错𬌗畸形、骨性Ⅲ类错𬌗伴上颌骨发育不足和骨性Ⅲ类错𬌗伴下颌骨发育过度患者之间的髁突-关节窝的形态差异。方法 收集2021年3月至2022年12月于南京医科大学附属口腔医院正畸科就诊患者,其中包括骨性Ⅰ类错𬌗畸形、骨性Ⅲ类错𬌗伴上颌骨发育不足和骨性Ⅲ类错𬌗伴下颌骨发育过度患者共58例,行锥形束CT扫描,利用Mimics 20.0软件和Dolphin 11.9软件对髁突和关节窝的相关角度及线性指标进行测量评估,采用SPSS 26.0软件进行统计学分析。结果 骨性Ⅰ类错𬌗畸形、骨性Ⅲ类错𬌗伴上颌骨发育不足和骨性Ⅲ类错𬌗伴下颌骨发育过度患者,每组患者的左侧和右侧的髁突和关节窝形态一致,差异无统计学意义(P>0.05);骨性Ⅲ类错𬌗伴上颌骨发育不足和骨性Ⅲ类错𬌗伴下颌骨发育过度患者均较骨性Ⅰ类错𬌗畸形患者的髁突上部高度增加(P<0.05);骨性Ⅲ类错𬌗伴下颌骨发育过度的患者较骨性Ⅰ类错𬌗畸形患者的关节结节后斜面的倾斜度和关节窝高度减小(P<0.05);骨性Ⅲ类错𬌗伴上颌骨发育不足和骨性Ⅲ类错𬌗伴下颌骨发育过度患者之间的各测量值差异均无统计学意义(P>0.05)。结论 三组双侧颞下颌关节基本对称,差异无统计学意义;骨性Ⅰ类错𬌗畸形与骨性Ⅲ类错𬌗畸形在髁突上部高度、关节结节后斜面倾斜度和关节窝高度存在显著差异;但在骨性Ⅲ类错𬌗畸形中,上颌骨发育不足患者和下颌骨发育过度患者的颞下颌关节的髁突-关节窝形态特征虽有差异,但不具有统计学意义。

Abstract:

Objective To study the morphological differences of condyle-fossa in people with skeletal Class Ⅰ malocclusion and skeletal Class Ⅲ malocclusion who were divided into maxillary deficiency and mandibular prognathism. Methods The CBCT images of bilateral temporomandibular joint (TMJs) in 58 patients with skeletal Class Ⅰ and Ⅲ were selected, who were treated in the Department of Orthodontics, Affiliated Hospital of Stomatology Nanjing Medical University from March 2021 to December 2022. Relative angular and linear measurements of the condyle-fossa were conducted with Mimics 20.0 and Dolphin 11.9 software. The data was analyzed with SPSS 26.0 software. Results There was no statistical difference in the measurement items of TMJs between the left and right sides(P<0.05)in patients with skeletal Class Ⅰ and Ⅲ malocclusion. The condyle height of both skeletal Class Ⅲ malocclusion was higher than the skeletal Class Ⅰ malocclusion(P<0.05). In addition, the comparisons of the skeletal Class Ⅲ malocclusion with mandibular prognathism and the skeletal Class Ⅰ malocclusion showed statistical differences in the articular eminence inclination and the height of the glenoid fossa(P<0.05). However, the intergroup comparisons of the skeletal Class Ⅲ malocclusion showed no statistical differences in all morphological measurements(P>0.05). Conclusion There was no obvious difference between bilateral temporomandibular joints among the three groups. Significant differences were shown between skeletal Class Ⅰ and Ⅲ malocclusion in terms of condylar height, the central joint space, the articular eminence inclination, and the height of the glenoid fossa. While there were differences in the morphological measurements of TMJs among patients with maxillary deficiency and mandibular prognathism of skeletal Class Ⅲ malocclusion, these disparities did not have statistical significance.

Key words: condylar, glenoid fossa, skeletal Class Ⅲ malocclusion, maxillary deficiency, mandibular prognathism
