The implant-supported, maxillary anterior, fixed-detachable prosthesis is often fabricated with a gingival flange to enhance esthetics and phonetics. However, only the dentist can remove the prosthesis, and the esthetic labial flange invariably impedes patient access for cleaning. A two-piece, fixed-detachable prosthesis that incorporates a substructure retained with conventional set screws and a superstructure retained with precision attachments has been developed. The substructure is contoured to facilitate patient access for oral hygiene because it will be covered by the superstructure and neither esthetics nor phonetics is a concern. The superstructure is easily removed by the patient for routine cleaning and can be designed for favorable esthetics and phonetics. This article reviews and describes the procedures for fabrication of this precision attachment-retained, implant-supported prosthesis.
种植体支持的上颌前部固定可摘义齿通常带有牙龈突来改善美观和发音。然而，只有牙医才能取下义齿，而美观的唇侧突总是妨碍患者进行清洁。一种两件式固定可摘义齿已被研发出来，它包括一个用传统固定螺钉固定的下部结构和一个用精密附件固定的上部结构。下部结构的外形便于患者进行口腔卫生清洁，因为它将被上部结构覆盖，所以美观和发音都不成问题。上部结构患者可轻松取下进行日常清洁，并且可以设计成具有良好的美观和发音效果。本文回顾并描述了这种精密附件固定、种植体支持义齿的制作过程。
