Infraocclusion of deciduous molars is a clinical disturbance that occurs during primary and mixed dentition and has some orthodontic implications. Infraoccluded teeth are believed to be potential sites of malocclusion, with a risk of tipping neighbouring teeth and losing space. This systematic review aims to analyse the management of primary molars infraocclusion and to provide updated guidelines.
A literature search was performed using PubMed, Scopus, and Web of Science databases from 1 January 2017 to 28 November 2022. The inclusion criteria were: studies only on human subjects, open access studies, case reports, randomised trials, retrospective, observational studies, and English language.
A total of 372 publications were identified from the databases and a final number of nine studies were included in the review for qualitative analysis.
Management of patients suffering from infraocclusion depends on the severity, age at diagnosis, and presence of succeeded premolars. Early diagnosis of infraoccluded primary elements is fundamental and cannot be postponed. Preservation of the primary molars may be a valid option with long-term stability if there is no or moderate primary molar infraocclusion, root resorption of less than half of the root, and no decay or restoration.
乳牙低位咬合是一种发生在乳牙列和混合牙列期的临床病症，具有一定的正畸学意义。低位咬合的牙齿被认为是错牙合畸形的潜在部位，存在使邻牙倾斜和丧失间隙的风险。本系统评价旨在分析乳牙低位咬合的治疗方法并提供最新指南。
于2017年1月1日至2022年11月28日使用PubMed、Scopus和Web of Science数据库进行文献检索。纳入标准为：仅针对人类受试者的研究、开放获取研究、病例报告、随机试验、回顾性研究、观察性研究以及英文文献。
从数据库中总共识别出372篇出版物，最终有9项研究纳入本评价进行定性分析。
乳牙低位咬合患者的治疗取决于病情严重程度、诊断时的年龄以及后继前磨牙的情况。早期诊断乳牙低位咬合至关重要，不能延迟。如果乳牙低位咬合程度较轻或无低位咬合、牙根吸收少于一半且无龋坏或修复体，保留乳牙可能是一种具有长期稳定性的有效选择。
