Temporomandibular joint disorders (TMDs) following tooth loss may or may not be prevalent, but the risk of developing these disorders is always there due to changes in occlusion and vertical dimension, leading to changes in the disc-fossa relationship. The purpose of this systematic review was to evaluate the prevalence and severity of temporomandibular joint (TMJ) disorder in partially versus completely edentulous patients. An elaborated literature search was conducted in PubMed/Medline, Scopus, Web of Science, Lilacs, and Google Scholar databases including all articles about varied effects of partial and complete edentulism on the TMJ published from January 1, 2000, to January 1, 2022. After the meticulous screening, only publications which fulfilled the inclusion parameters were ultimately selected for full-text evaluation and tested for bias using the Joana Briggs Institute Appraisal tools for cross-sectional, case-control, and cohort studies. A total of 547 articles from various electronic databases and manual searches were found. After eliminating the duplicates and thorough screening, 13 studies were included for qualitative synthesis. Most of the studies demonstrated at least one or two signs of the presence of TMDs following tooth loss, the intensity/frequency of which increased in proportion to the number of missing teeth.
颞下颌关节紊乱症（TMDs）在牙齿缺失后可能存在，也可能不存在，但由于咬合和垂直距离的改变，导致关节盘-牙槽窝关系改变，这些疾病的发生风险始终存在。本系统评价的目的是评估部分和完全无牙患者的颞下颌关节（TMJ）紊乱的患病率和严重程度。在 PubMed/Medline、Scopus、Web of Science、Lilacs 和 Google Scholar 数据库中进行了详细的文献检索，包括 2000 年 1 月 1 日至 2022 年 1 月 1 日期间发表的关于部分和完全无牙对 TMJ 影响的各种文章。经过细致的筛选，只有符合纳入标准的出版物才会进行全文评估，并使用 Joana Briggs 研究所评估工具对横断面、病例对照和队列研究进行偏倚测试。从各种电子数据库和手动搜索中找到了 547 篇文章。经过重复和仔细筛选，最终纳入了 13 项研究进行定性综合分析。大多数研究显示，牙齿缺失后至少存在一种或两种 TMD 存在的迹象，其发生的频率和强度随着缺失牙齿数量的增加而增加。
