Abstract：
OBJECTIVE: The aim of this systematic review was to compare treatment outcomes in terms of implant survival rate, marginal bone loss, and patient-reported outcome measures (PROMs) between narrow-diameter implants and regular-diameter implants (RDIs) for mandibular implant overdentures (MIOs).
METHODS: This study was based on the methodology adapted as per Cochrane. Medline, Embase, the Cochrane Central Register of Controlled Trials, Web of Science, and Scopus were searched for pertinent studies published by July 22, 2022. Outcome parameters included in this meta-analysis were implant survival rate, marginal bone loss, visual analogue scale score for patient satisfaction, and value of oral health impact profile.
RESULTS: A total of 782 non-duplicate articles and 83 clinical study registrations were identified from database and hand searches, of which 26 were eligible for full-text searches. Finally, 12 publications reporting on 8 independent studies were included in this review. In the meta-analysis, implant survival rate and marginal bone loss did not significantly differ between narrow-diameter implants and RDIs. Regarding RDIs, narrow-diameter implants were associated with significantly better outcomes in general patient satisfaction and oral health-related quality of life than RDIs for mandibular overdentures.
CONCLUSIONS: Narrow-diameter implants have competitive treatment outcomes compared to RDIs in terms of implant survival rate, marginal bone loss, and PROMs. [Correction added on July 21, 2023, after first online publication: The abbreviation RDIs was changed to PROMs in the preceding sentence.] Thus, narrow-diameter implants might be an alternative treatment option for MIOs in situations with limited alveolar bone volume.

摘要：
目的：本系统评价的目的是比较植入物存活率方面的治疗结果，边缘性骨丢失,和患者报告的下颌种植覆盖义齿的窄直径植入物和规则直径植入物之间的结果测量。
方法：本研究基于根据Cochrane调整的方法。Medline,Embase,Cochrane中央受控试验登记册,WebofScience,和Scopus被搜索到2022年7月22日发表的相关研究。这项荟萃分析中包括的结果参数是植入物存活率，边缘性骨丢失,患者满意度的视觉模拟量表评分，和口腔健康影响概况的价值。
结果：从数据库和手工搜索中确定了782篇非重复文章和83篇临床研究注册，其中26人符合全文搜索条件。最后,本综述包括12篇报告8项独立研究的出版物。在荟萃分析中，狭窄直径植入物和规则直径植入物的植入物存活率和边缘骨丢失没有显著差异.关于患者报告的结果指标，对于下颌覆盖义齿,与常规直径植入物相比,窄直径植入物在总体患者满意度和口腔健康相关生活质量方面具有显著更好的结局.
结论：就植入物存活率而言，与规则直径植入物相比，窄直径植入物具有竞争性治疗效果。边缘性骨丢失,和患者报告的结果指标。因此，在牙槽骨体积有限的情况下，窄直径植入物可能是下颌植入物覆盖义齿的替代治疗选择。本文受版权保护。保留所有权利。
