Abstract

Introduction: Mandibular implant-supported overdentures (IODs) show higher retention than conventional complete dentures. However, there is no consensus on the best attachment to ensure resistance to vertical displacement. The most used are o-ring and bar-clip. This systematic review answered "Which type of attachment for overdenture prosthesis provides higher retention: o-ring or bar-clip?

Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was followed and registered in the International Prospective Register of Systematic Reviews (PROSPERO). The search was applied to 5 databases and grey literature. The selection process occurred in two blinded steps by the reviewers following the eligibility criteria: a randomized clinical trial comparing retention between o-ring and bar-clip in IODs. The risk of bias was analyzed by RoB II.

Results: 206 articles were found, and after removing the duplicates 136 were evaluated by title and abstract of which 24 were selected for full reading, 5 met the eligibility criteria, and all had a high risk of bias. The bar-clip provided higher retention than o-ring in four studies.

Conclusions: The bar-clip system provides a higher retention rate than the o-ring. In addition, the selection of attachment systems is dependent on the patient's anatomical-functional and economic conditions.

O形环和条形卡环：义齿覆盖修复体固位的比较分析 - 系统性综述。

导言：与传统的全口义齿相比，下颌种植体支持覆盖义齿（IOD）具有更高的固位力。然而，对于确保抗垂直位移的最佳连接方式还没有达成共识。使用最多的是 O 形环和条形卡环。本系统综述回答了 "O形环和条形夹哪种义齿连接体的固位效果更好？遵循系统综述和元分析首选报告项目（PRISMA），并在国际系统综述前瞻性注册中心（PROSPERO）注册。检索范围包括 5 个数据库和灰色文献。筛选过程由审稿人按照资格标准分两步进行：比较 IOD 中 O 形环和条形夹保留率的随机临床试验。结果：共找到 206 篇文章，去除重复文章后，根据标题和摘要对 136 篇文章进行了评估，其中 24 篇被选中进行全文阅读，5 篇符合资格标准，所有文章的偏倚风险都很高。在四项研究中，条形夹的留置率高于O形环：结论：条形夹系统的固定率高于 O 形环。结论：条形夹系统的固定率高于 O 形环。此外，固定系统的选择取决于患者的解剖功能和经济条件。
