摘要:

目的 比较不同颞下颌关节骨质情况患者的前后𬌗平面等指标。 方法 纳入306例患者的初诊锥形束CT(CBCT)和头颅侧位片,根据关节骨质情况分为3组:双侧正常组、骨关节病(OA)组、疑似OA组。比较3组患者前牙𬌗平面(AOP)、后牙𬌗平面(POP)等指标,去除混杂因素影响后建立回归方程,并进行𬌗平面与其余指标的相关性分析。 结果 SNA、SNB、FMA、SN-MP、Ar-Go、S-Go与𬌗平面指标具有相关性;与双侧正常及疑似OA组相比,OA组患者FH-OP平均增加1.67°;FH-POP平均增加1.42°;FH-AOP平均增加2.05°。 结论 OA患者的𬌗平面较陡,下颌骨向下后旋转,下颌升支、下颌体部、后面高较小,临床上对于这类患者应注意颞下颌OA的潜在危险;SNB、FMA、SN-MP、Ar-Go、S-Go与𬌗平面指标有较好相关性。

Abstract:

Objective The aim of this study was to compare the anterior and posterior occlusal plane characteristics of patients with different temporomandibular joint osseous statuses. Methods A total of 306 patients with initial cone beam CT (CBCT) and cephalograms were included. They were divided into three groups on the basis of their temporomandibular joint osseous status: bilateral normal (BN) group, indeterminate for osteoarthrosis (I) group, and osteoarthrosis (OA) group. The anterior and posterior occlusal planes (AOP and POP) of the different groups were compared. Then, the regression equation was established after adjusting for confounding factors, and a correlation analysis between the occlusion planes and other parameters was performed. Results SNA, SNB, FMA, SN-MP, Ar-Go, and S-Go were correlated with the occlusal planes. Relative to the BN and I groups, the FH-OP of the OA group increased by 1.67° on the average, FH-POP increased by 1.42° on the average, and FH-AOP increased by 2.05° on the average. Conclusion The occlusal planes were steeper in the patients with temporomandibular osteoarthrosis than in the patients without it, and the mandible rotated downward and backward. The height of the mandibular ramus, the mandibular body length, and the posterior face height were small. In clinical practice, attention should be given to the potential risk of temporomandibular joint osteoarthrosis in such patients. In addition, SNB, FMA, SN-MP, Ar-Go, S-Go, and occlusal planes had moderate correlations.
