摘要/Abstract

摘要：

骨性Ⅱ类错𬌗畸形是以上颌前突和(或)下颌后缩为主要特征的错𬌗畸形。近年来,骨性Ⅱ类病例的下颌平面角控制逐渐成为讨论焦点,例如下颌后缩病例期望逆旋下颌平面以改善侧貌、磨牙远移病例担忧下颌平面顺旋会影响侧貌等。不同文献间的结果存在争议,本综述探讨后牙压低、后牙伸长、Ⅱ类牵引、磨牙远移和下颌前导等对下颌平面角的影响,期望能为临床医生提供参考。

Abstract:

The skeletal Class Ⅱ malocclusion is characterized by the maxillary protrusion and/or mandibular retraction. In recent years, the mandibular plane control of the skeletal Class Ⅱ malocclusion has gradually become a hot topic. For example, patients with mandibular retraction expected to improve the lateral appearance by the mandibular counterclockwise rotation; patients receiving molar distalization were concerned that the lateral appearance might be affected due to the potential mandibular clockwise rotation. The results in different articles were controversial. This review explored the effect of posterior tooth intrusion, posterior tooth extrusion, Class Ⅱ elastics, molar distalization and mandibular advancement on the mandibular plane angle to provide reference for clinicians.

Key words: skeletal Class Ⅱ, mandibular plane angle, vertical control, mandibular retraction, mandibular counterclockwise rotation
