摘要:

目的 研究伴颞下颌关节紊乱病(temporomandibular disorders,TMD)的错牙合患者不同颌位髁突位置的差异,进一步探讨髁突偏移和错牙合因素对TMD的影响。方法 按照试验纳入标准分别收集无TMD个别正常牙合组(A组,n=10)、伴TMD个别正常牙合组(B组,n=8)、无TMD错牙合组(C组,n=9)和伴TMD错牙合组(D组,n=20),采用CadiaxⅣ和CPM(condylar position measurement)分别记录4组试验对象牙尖交错位(intercuspal position,ICP)和参考位置(reference position,RP)髁突的位置,游标卡尺测量下颌从RP位到ICP位髁突位置的偏移量和偏移方向,采用 SPSS 26.0软件包对所得结果进行统计学分析。结果 矢状向,A组与B组、C组与D组、A组与D组髁突偏移量均差异有统计学意义(P<0.01),垂直向D组右侧髁突的位移量大于A组,差异有统计学意义(P<0.05),其余各组间差异无统计学意义。髁突横向的偏移量在4组组间均不具有统计学差异。A组和D组髁突偏移方向占比最大的为前上,B组和C组中髁突偏移占比最大的为后上。结论 伴TMD人群常伴有RP-ICP髁突矢状向偏移。无TMD的错牙合患者RP-ICP的髁突位移与无TMD正常牙合人群无显著差异。有TMD错牙合患者较无TMD正常牙合在矢状向和垂直向均易发生髁突的偏移。

Abstract:

Objective To investigate the differences of condylar position in patients with temporomandibular disorders(TMD), and to further explore the effects of condylar position displacement and malocclusion factors on TMD. Methods According to the inclusion criteria, normal occlusion subjects without TMD(group A, n=10), normal occlusion subjects with TMD(group B, n=8), malocclusion subjects without TMD(group C, n=9) and malocclusion subjects with TMD(group D, n=20) were collected. Condylar position measurement(CPM) and Cadiax Ⅳ were used to locate the position of condyle in RP and ICP, and the displacement and direction of condyle in three-dimensional direction from RP to ICP were measured by vernier caliper. All the data were averaged three times and analyzed by SPSS26.0 statistical software. Results In the sagittal direction, the condylar displacement of group A and group B, group C and group D, and group A and group D had statistical differences(P<0.01). The displacement of the right condyle in the vertical direction of group D was greater than that of group A, and the difference was statistically significant(P<0.05). The difference among other groups was not statistically significant. There was no significant difference in the lateral displacement of condyle between the four groups. In group A and group D, the largest proportion of condyle deviation was anterior up, while in group B and group C, the largest proportion of condyle deviation was posterior up. Conclusion RP-ICP condylar sagittal displacement is common in people with TMD. The condyle displacement of RP-ICP in malocclusion patients without TMD is not significantly different from that in normal occlusion patients without TMD. Patients with TMD malocclusion are more likely to have condylar displacement in sagittal direction and vertical direction than normal occlusion without TMD.
