Abstract

Purpose: The main problem related to conventional attachments for overdentures is the loss of retention. The purpose of this review was to analyze the mechanical properties of different polymeric attachments presented in the literature to consider their clinical use viability.

Materials and methods: This work was registered in Open Science Framework (osf. io/7j9vz) and followed the Preferred Reporting Items for Systematic Review and Meta- Analysis (PRISMA). A search of two independent reviewers of articles was performed on Embase, Pubmed, Science Direct, and Scopus databases.

Results: The databases found a total of 1803 references and 1226 articles titles. A total of 21 articles were included in this scoping review. The polymers used for manufacturing attachments were polyacetal, polylactic acid, poly(ether-ether-ketone), polytetrafluoroethylene, polyethylene, and poly(ethylene terephthalate).

Conclusion: Polyamide Locators demonstrated highest initial and final retention, indicating superior long-term stability. Among emerging materials, polyacetal and polylactic acid attachments also showed excellent retention, supporting clinical applicability.

用于固位覆盖义齿的聚合物附着体力学性能的系统综述：传统与新型的比较。

目的：常规附着体覆盖义齿的主要问题是固位丧失。本综述的目的是分析文献中提出的不同聚合物附着物的力学性能，以考虑其临床应用的可行性。材料和方法：本工作已在开放科学框架（osf）中注册。io/7j9vz)，并遵循系统评价和元分析首选报告项目（PRISMA）。在Embase、Pubmed、Science Direct和Scopus数据库上对两位独立的文章审稿人进行了搜索。结果：共检索到参考文献1803篇，文献标题1226篇。本次范围综述共纳入21篇文章。用于制造附着物的聚合物有聚缩醛、聚乳酸、聚醚醚酮、聚四氟乙烯、聚乙烯和聚对苯二甲酸乙酯。结论：聚酰胺定位器具有最高的初始和最终保留率，具有较好的长期稳定性。在新兴材料中，聚缩醛和聚乳酸附着体也表现出良好的固着性，支持临床适用性。
