The following values was measured: angle of cusp line between the second and third molar, impact state and depth, distance from Rickett's Xi to distal cusp of third mandibular molar along the occlusal plane, anterior border of ramus to the third mandibular molar, distance from projection of distal contact point of maxillary third molar to intersection of pterygoid vertical on occlusal plane.The change between pre-and post-treatment was calculated and analyzed with SPSS10.0 software package.α angle, Xi-LTM, R-LTM, R-LTM were tested with independent-sample t test, impact state and depth was tested with Chi-square test. Influence of age on the values was also evaluated.
测量治疗前后的第二、第三磨牙牙尖连线角度、阻生状态和深度，Rickett's Xi点到下颌第三磨牙远中尖距离、下颌支前缘到第三磨牙远中尖距离、翼上颌裂切线到上颌第三磨牙后缘的距离及上、下磨牙的前移量，计算治疗前后各变量的差值，采用SPSS10.0软件包进行统计学分析，α角、Xi-LTM、R-LTM、R-LTM用t检验，阻生状态和深度用χ^2检验，比较年龄因素对各指标的影响。
