BACKGROUND
New attachment systems are released for mandibular two-implant overdentures often without evidence-based support. Biomaterial aspects are now the parameters considered when choosing the appropriate attachment. Studies regarding their properties remain scarce.
PURPOSE
The purpose of this review was to help the clinician in selrcting the most adapted stud attachments according evidence-based dentistry.
MATERIALS AND METHODS
An electronic search was conducted using specific databases (PubMed, Medline, and Elsevier libraries). Peer-reviewed articles published in English up to July 2014 were identified. Emphasis was given on the biomaterial aspects and technical complications. No hand search was added.
RESULTS
The electronic search generated 115 full-text papers, of which 84 papers were included in the review. The majority were clinical and in vitro studies. Some review articles were also considered. Papers reported survival and failures of overdenture connection systems. Emphasis was laid on attachment deformation.
CONCLUSION
Implant overdentures long-term follow-up studies may provide useful guidelines for the clinician in selecting the type of attachment system and overdenture design. Locator attachments are more and more used, with lesser complications reported.
背景
下颌双种植覆盖义齿的新型附着系统常常在缺乏循证依据的情况下推出。生物材料方面如今是选择合适附着体时考虑的参数。关于其性能的研究仍然很少。
目的
本综述的目的是根据循证牙科帮助临床医生选择最合适的球帽附着体。
材料与方法
使用特定数据库（PubMed、Medline和爱思唯尔图书馆）进行电子检索。确定截至2014年7月以英文发表的经同行评审的文章。重点关注生物材料方面和技术并发症。未进行手工检索。
结果
电子检索产生了115篇全文论文，其中84篇论文纳入本综述。大多数是临床和体外研究。也考虑了一些综述文章。论文报告了覆盖义齿连接系统的存留率和失败情况。重点在于附着体变形。
结论
种植覆盖义齿的长期随访研究可能为临床医生选择附着体系统类型和覆盖义齿设计提供有用的指导。Locator附着体的使用越来越多，报告的并发症较少。
