为探讨儿童及少年颞下颌关节紊乱综合征（ＴＭＪＤ）患者的接触状况，本研究利用接触点计算机图像分析系统，对３２例少年儿童ＴＭＪＤ患者正畸治疗前后正中位的硅橡胶咬合记录进行了定性与定量分析。结果表明，正畸治疗减少了前牙接触点数目；减小了每个接触点的平均面积；增加了正中止接触部位的接触点；减少了斜面接触类型。作者认为，正畸治疗可以提高少年儿童ＴＭＪＤ患者型的稳定性。
In order to explore the contact status of TMJD in children and adolescents, this study used the contact point computerized image analysis system to characterize the occlusion records of silicone rubber in 32 children with TMJD before and after orthodontic treatment And quantitative analysis. The results showed that orthodontic treatment reduced the number of contact points of the anterior teeth, reduced the average area of each contact point, increased the contact point of the contact point being stopped, and reduced the contact type of the bevel. The author believes that orthodontic treatment can improve the stability of juvenile TMJD patients.
