The displacement of a third molar is a rare occurrence, but it could lead to serious and/or life threatening complication. Aim of this review is to understand the most correlated causes of displacement and the possible solutions proposed in literature to avoid and solve this complication for maxillary and mandibular third molars at the appropriate time.
A search for "third molar displacement" was performed by using Pubmed database. Articles referred to soft tissues displacement, from 1957 to 2018, were included in the review. The references lists of all eligible articles were examined and additional studies were added to the review only if indexed on Pubmed. All the articles on maxillary sinus displacement and the dislocation of dental fragments or surgical equipment were excluded.
From a total of 134 results, 68 articles were examined for satisfying inclusion criteria. 18 articles were excluded because not inherent with the topic; 19 articles on infratemporal space, 11 on sublingual space, 9 on submandibular space, 11 on lateral pharyngeal space displacement were considered congruent for the review and included.
The displacement of the third molar in deeper tissues could be avoided by the use of proper surgical procedures and instrumentarium. If displacement occurs, and the operator could not reach the tooth in safe conditions, the patient should be immediately referred to a maxillo-facial surgeon, because of the possibility of further displacement or the onset of hazardous or potentially fatal infections in vital regions.

第三磨牙移位是一种罕见情况，但可能导致严重和/或危及生命的并发症。本综述的目的是了解最相关的移位原因以及文献中提出的在适当时候避免和解决上颌和下颌第三磨牙这种并发症的可能解决方案。
通过使用PubMed数据库搜索“第三磨牙移位”。纳入1957年至2018年期间涉及软组织移位的文章进行综述。检查所有符合条件文章的参考文献列表，仅当文章在PubMed上被索引时才将其他研究添加到综述中。排除所有关于上颌窦移位以及牙碎片或手术器械脱位的文章。
在总共134条结果中，对68篇文章进行了检查以确定是否符合纳入标准。18篇文章因与主题无关而被排除；19篇关于颞下间隙、11篇关于舌下间隙、9篇关于下颌下间隙、11篇关于咽旁间隙移位的文章被认为与综述相关并被纳入。
通过使用适当的手术程序和器械可以避免第三磨牙在更深组织中的移位。如果发生移位，并且操作者在安全条件下无法触及牙齿，则应立即将患者转诊至颌面外科医生处，因为可能会进一步移位或在重要区域发生危险或潜在致命感染。第三磨牙、智齿、上颌、下颌、移位。
