问题陈述许多作者报告了与部分可移动牙修复体(PRDP)相关的远端种植体的放置，以使修复更加稳定。这一策略可能代表了一种解决PRDP侵入性移动问题和降低治疗成本的选择。目的本系统综述的目的是评价目前关于放置与下颌PRDP相关的远端种植体以提高患者满意度以及基牙和远中种植体的临床性能的证据。材料和方法两位独立的修复体专家评审员进行了这项系统综述。使用PubMed和Cochrane图书馆数据库中截至2014年5月发表的与远端种植体相关的PRDP的精选临床研究进行搜索。数据摘录表格用于收集一般信息：作者、标题、发表年份、研究目的、证据水平、参与者数量、使用的种植体数量、种植体系统、种植体长度和直径、基牙类型、咀嚼性能、患者满意度、种植体平均骨丢失、基牙平均骨丢失、修复并发症、随访期和种植体存活率。结果最初的电子检索共鉴定出231篇研究，手工检索共鉴定出15篇研究(共246篇)。经过标题、摘要阅读和去掉重复后，获得了43篇研究的全文。排除不符合纳入标准的文献(28篇)，提取15篇研究的数据。7篇是回溯性研究，1篇是交叉试点研究，2篇是病例系列，2篇是配对临床研究，3篇是病例报告，表明大量入选研究的方法学质量较低。结论在不降低种植体存活率的情况下，使用与种植体相关的PRDP将Kennedy I类牙修复体转换为III类修复体对患者有好处，可以提高患者的满意度和咀嚼能力。考虑到基牙存活率，临床研究仍然缺乏可比较的方法来确定与PRDP相关的远中种植体的使用方案。长期的、前瞻性的临床试验仍需了解哪些种植基牙可提高基牙存活率。
Statement of problemA number of authors have reported the placement of a distal implant associated with a partial removable dental prosthesis (PRDP) to make this rehabilitation more stable. This strategy may represent an option for resolving the problem of the intrusive movements of the PRDP and for reducing treatment costs.PurposeThe purpose of this systematic review was to evaluate the current evidence about the placement of a distal implant associated with a mandibular PRDP to improve patient satisfaction and the clinical performance of the abutment tooth and distal implant.Material and methodsTwo independent prosthetic specialist reviewers conducted this systematic review. The search was performed using selected clinical studies with PRDP associated with distal implants published in English up to May 2014 from the PubMed and Cochrane Library databases. A data extraction form was developed to collect general information: authors, title, year of publication, aim of study, level of evidence, number of participants, number of implants used, implant system, implant length and diameter, abutment type, masticatory performance, patient satisfaction, implant mean bone loss, abutment tooth mean bone loss, prosthetic complications, follow-up period, and implant survival rate. The quality of the selected studies and the risk of bias were also reported.ResultsThe initial electronic search identified 231 studies, and the manual process identified 15 studies (total of 246 studies). After the title and abstract reading and the removal of duplicates, the full texts of 43 studies were obtained. The articles that did not meet the inclusion criteria were excluded (28 studies), and the data from 15 studies were extracted. Seven were retrospective studies, 1 a crossover pilot study, 2 case series, 2 paired clinical studies, and 3 case reports, demonstrating that a high number of the selected studies were of low methodological quality. Nevertheless, the high survival rates for PRDP associated with dental implants have been described.ConclusionsThe use of a PRDP associated with dental implants to convert a Kennedy class I to class III dental prosthesis benefits patients by improving their satisfaction and masticatory abilities without decreasing implant survival rates. Considering the abutment tooth survival rate, clinical studies with comparable methodology are still lacking to define protocols regarding the use of distal implants associated with PRDP. Long-term, prospective clinical trials are still needed to understand which implant abutments increase abutment tooth survival rate.
