摘　　要：低位咬合是指牙齿在主动萌出后保持静止,而相邻牙齿持续萌出,随着骨骼的生长,牙齿[牙合]面低于[牙合]平面的现象。低位咬合最常见于儿童,以下颌第二乳磨牙多发。牙齿发生低位咬合的年龄越早,其导致的咬合问题越严重。本文从第二乳磨牙低位咬合的病因和治疗等方面进行阐述,以期为第二乳磨牙低位咬合的临床治疗提供参考。Infraocclusion is a phenomenon that the relative occlusal growth of a tooth stops after the period of active eruption and then the tooth becomes depressed below the occlusal plane.Infraocclusion occurred more commonly in children and the mostly affected teeth were the primary mandibular second molars.The occlusal problem caused by infraocclusion may progressively worsen with age.This review summarizes the etiology,diagnosis and treatment of infraoccluded second primary molars,so as to provide reference for the dental clinicians.
