Occlusal contacts were examined in a sample of 32.8-17 Years old TMJD patients before and after orthodontic treatment. Computer-aided video system was applied to the silicone occlusal record obtained in the intercuspid position to assess the quantitative and qualitative changes of occlusal contacts. The results showed that after orthodontic treatment, the mean number of contacts on anterior teeth decreased, the mean area per contact decreased, the location of contacts on centric stops increased and the contacts on inclined plane were decreased. All of these indicated that the occlusal stability increased after orthodontic treatment.
在32名年龄在17至32岁的颞下颌关节紊乱病（TMJD）患者样本中，对正畸治疗前后的咬合接触情况进行了检查。将计算机辅助视频系统应用于在尖牙间位置获得的硅橡胶咬合记录，以评估咬合接触的定量和定性变化。结果显示，正畸治疗后，前牙的平均接触点数减少，每个接触点的平均面积减小，正中咬合位时接触点的位置上移，斜面接触减少。所有这些表明正畸治疗后咬合稳定性增加。
