摘　　要：目的探讨后牙间隙修复治疗前远中磨牙错位的矫治类型和相应方法.方法收集接受后牙间隙义齿修复前远中磨牙正畸调整患者30例,根据间隙修复方案和磨牙错位情况,分别采取近中移动磨牙关闭间隙,远中移动磨牙扩展义齿修复间隙和竖直磨牙3种方式进行正畸调整.结果 2例病例通过近中移动磨牙关闭间隙,其余28例病例按修复义齿设计的要求完成了磨牙的远中移动和竖直.结论少量间隙可以通过近中移动磨牙关闭;而远中移动和竖直是后牙间隙修复治疗前远中磨牙位置调整的主要类型.Objective To investigate the feature and clinic approach of orthodontic management on the distal molar position before prosthodontic restoration of dental space in posterior region.Methods 30 cases with dental space in posterior dentition and distal molar malposition were selected. According to the status of molar malposition and the prosthodontic treatment protocol,the orthodontic molar adjustment was carried out in three ways： mesial movement, distal movement,and upright.Results In 2 cases,dental space was closed by mesial movement of molar; in the other 28 cases,orthodontic distalization and/or upright of the distal molar were achieved according to the prosthodontic requirement.Conclusion Mesial movement of distal molar can sometimes be applied to close the minor space,while distalazition and upright correction are the major types of orthodontic management of distal molar position before prosthodontic treatment of posterior dental space.
