乳磨牙萌出障碍的研究进展

Research progress on the failure of tooth eruption in deciduous molars

摘要

牙齿萌出障碍多见于恒牙，在乳牙中比较少见。乳牙中主要累及乳磨牙，以下颌第二乳磨牙最为常见。乳磨牙萌出障碍病因诊断困难，发生机制尚不明确。临床上对乳磨牙萌出障碍的治疗方法尚未达成共识，观察、修复、拔除受累牙、外科松解或正畸牵引等方法是目前可参考的治疗手段，治疗方法的选择与乳磨牙萌出障碍的类型、严重程度、伴随症状以及继承恒牙情况等有关。本文围绕乳磨牙萌出障碍的病因、临床表现、分类以及治疗方法等展开综述，以期为乳磨牙萌出障碍的临床诊治提供一定的参考依据。

Abstract

Failure of tooth eruption is more common in permanent teeth than in deciduous teeth. The most commonly affected teeth are deciduous mandibular second molars in deciduous dentition. In addition, accurate diagnosis of tooth eruption failure is challenging for clinicians, and its exact etiology remains unknown. The consensus on the management of tooth eruption failure in deciduous molars has not been reached. At present, observation, restoration, extraction, surgical luxation, or orthodontic traction are the available treatment methods. Appropriate treatment options primarily rely on the type and severity of tooth eruption failure, the succeeding permanent teeth, and the accompanied complications. Thus, this article reviews the etiology, clinical manifestations, classification, and treatments of tooth eruption failure in deci-duous molars to provide some reference for related clinical diagnosis and treatments.
