The rehabilitation of the atrophic maxilla by means of implant-supported prostheses cannot always be achieved with fixed prostheses because of anatomic, esthetic, or economic issues, so for some patients the treatment of choice is a removable prosthesis. This article analyzes a new design for implant-supported overdentures with horizontal or faciolingual insertion. Its retention system is based on frictional forces or stepped interlocking horizontal surfaces and is appropriate for patients with skeletal Class II or III relationships with severe maxillary atrophies. The design facilitates implant-prosthetic hygiene and improved esthetics in patients with nonparallel implants by hiding abutment screws.
由于解剖学、美观或经济方面的问题,通过种植体支持的修复体来修复萎缩的上颌骨,并不总是能够实现固定修复体,因此对于某些患者来说,首选的治疗方法是可摘义齿。本文分析了一种带有水平或颊舌向插入的种植体支持覆盖义齿的新设计。其固位系统基于摩擦力或阶梯状互锁的水平表面,适用于骨骼 II 类或 III 类关系伴有严重上颌萎缩的患者。该设计通过隐藏基台螺丝,便于种植体-修复体的卫生维护,并改善非平行种植体患者的美观度。
