The aim of this article is to systematically review the literature on prosthodontic maintenance requirements of maxillary implant overdentures with different prosthodontic designs.
A standard approach of searching MEDLINE, PubMed, and Google Scholar databases as well as early online journal articles was followed. Hand-searching identified other relevant articles from the reference lists of the articles found. Selection criteria were details of prosthodontic maintenance related to different prosthodontic designs of maxillary implant overdentures, regardless of the dentition of the opposing arch or prosthesis.
From a total of 58 relevant studies identified, only 18 met the criteria. Several categories were used to document the prosthodontic maintenance of maxillary implant overdentures, usually with four or more splinted or unsplinted implants using different attachment systems. Aspects of patrix and matrix maintenance were primarily reported, although soft tissue complications were described frequently. Subjective information on relines and the rationale for minimizing overdenture fractures was found.
Prosthodontic maintenance requirements of maxillary overdentures are a direct consequence of the attachment system, together with differing numbers and distributions of implants. The reviewed literature does not provide a clear controlled indication of prosthodontic maintenance requirements of maxillary overdentures for different prosthodontic designs and attachment systems. Future standardization of maxillary implant overdenture design is recommended, and universally accepted criteria for reporting maxillary implant overdenture maintenance should be implemented to establish accurate comparative data analysis.
本文旨在系统回顾不同修复设计的上颌种植覆盖义齿修复体的临床维护需求。
通过对 MEDLINE、PubMed 和 Google Scholar 数据库以及早期在线期刊文章的标准检索方法，同时辅以手检，从已检索到的文章的参考文献中查找其他相关文章。选择标准为涉及不同上颌种植覆盖义齿修复设计的修复体维护的详细信息，无论对颌牙列或义齿的类型如何。
在总共确定的 58 篇相关研究中，只有 18 篇符合标准。研究使用了几种类别来记录上颌种植覆盖义齿的修复体维护情况，通常使用四个或更多个带有不同附着体系统的夹板式或非夹板式种植体。主要报告了牙冠和牙托的维护情况，尽管软组织并发症也经常被描述。关于衬里和尽量减少覆盖义齿折裂的理由的主观信息也被发现。
上颌覆盖义齿的修复体维护需求是附着体系统以及种植体数量和分布的直接结果。综述文献并未明确为不同修复设计和附着体系统的上颌覆盖义齿提供明确的临床维护需求指征。建议未来应标准化上颌种植覆盖义齿的设计，并实施普遍接受的上颌种植覆盖义齿维护报告标准，以建立准确的对比数据分析。
