中文摘要：

相较牙种植体支持的固定义齿,种植覆盖义齿具有治疗程序简便、易清洁、可有效恢复患者面容及费用相对低等优势;而相较传统全口义齿,种植覆盖义齿具有更强的固位力及舒适感等特点。因此,种植覆盖义齿在无牙颌患者的口腔功能重建中具有较高的临床应用价值。目前口腔临床上常用的种植覆盖义齿附着方式主要包括杆卡、球帽、套筒冠、Locator系统及磁性附着体等。虽然种类较多,但国内外文献缺乏全面而系统的评价和比较,另外我国部分种植科医生对各类附着支持系统的认识仍然不足。基于此,本文系统介绍了各类附着体的适应证及优缺点,比较各种附着体系统在固位、种植体周围软硬组织变化及患者满意度方面的差异性,希望能为口腔医生应用种植覆盖义齿修复重建无牙颌患者口腔功能时,提供一定的参考。

With the advent of population aging in our country, the implant-supported overdenture has a broad prospect of clinical application in treating edentulous patients. Implant-supported overdenture mainly includes bar-clip attachment, ball attachment, telescopic coping attachment, magnetic attachment, locator and other attachments.

This paper, aimed to provide useful information for choosing the optimal type of implant-supported overdenture in reconstruction of patients＆#39; oral function and facial aesthetics, by comparing the patients＆#39; satisfaction, the retention and stability and the condition of the hard and soft tissues around the implant after using the five attachment systems.
