Unfavorable angulation of dental implants is a common complication that may make the design of the prosthetic device difficult and may compromise its function, access for oral hygiene procedures, and esthetic appearance. When the use of angulated abutments makes the prosthetic design unaceptable, the use of a double cast fixed detachable prosthodontic procedure may be required, which includes a cast substructure retained with conventional set screws to support a cast metal ceramic superstructure retained by semiprecision attachments and friction. This procedure improves access for oral hygienic procedures and offers better control over the esthetics and the function of the restoration.
牙种植体的不利角度是一种常见并发症，可能会使修复装置的设计变得困难，并可能损害其功能、口腔卫生操作的便利性以及美观。当使用角度基台会使修复设计不可接受时，可能需要采用双重铸造固定可摘义齿修复程序，该程序包括一个用传统定位螺钉固定的铸造下部结构，以支撑一个由半精密附件和摩擦力固定的铸造金属陶瓷上部结构。此程序改善了口腔卫生操作的便利性，并能更好地控制修复体的美观和功能。
