Methods30 nonextraction patients treated in the department of orthodontics in Shandong University in the same time period were enrolled in this study. The threepoint bending test was used to measure the strain and stress of arch wires at 37?℃.

方法选取山东大学口腔医学院正畸科同一时期内收治的30例上颌后牙段基本无拥挤的非拔牙矫治患者，利用三点弯曲试验装置（MTS Tytron 250， USA），检测未经使用、使用4周、8周及12周的镍钛弓丝在37？

Meta analysis was used to comprehensively quantitatively analyze the upper lip with esthetic plane and soft tissue plane before and after extraction and nonextraction treatment. According to homogeneity test, fixed effect model and random effect model were adopted to calculate weighted mean difference and 95% confidence interval (95% CI).

运用meta分析技术对拔牙与非拔牙矫治前后上下唇与审美平面及软组织平面的距离进行综合定量分析，根据资料异质性检验，采用固定效应模型及随机效应模型，计算合并加权均数差及其95%CI。

Objective To evaluate the nonextraction orthodontic therapy effects of multiloop edgewise arch wire on patients who had previously been classified as orthognathic surgical cases.

目的 使用多曲方丝弓(multiloop edgewise wire arch， MEAW)技术对恒牙期骨性Ⅲ类错手术适应证患者进行非拔牙矫治并观察其疗效。

A discriminate function, Z=0.952X_1 +0.591X_2(U1-Apgmm)–0.430X_3 was produced by multiplefactorial discrminate analysis. Z≥0 is an indication of extraction ,and Z is anindication of nonextraction on the other side.

将这些指标通过逐步判别分析得出的判别方程为：Z=0.952x_1+0.591x_2(U1-Apgmm)-0.430x_3，有助于这两种治疗方法的选择，Z≥0时，拔牙的可能性较大，Z﹤0时，不拔牙的可能性较大。

Studies have reported that the primary cause of fragment loss is new dental trauma or the nonphysiological use of the restored tooth.

研究认为，牙碎片缺失的原发性原因是新近牙体创伤或对已修复牙齿施加非生理性作用力。
