As an alternative to complete dentures, overdentures are well established as a sound therapeutic modality for patients with terminal dentition. By utilizing natural tooth roots and their periodontal structures to aid in support, overdentures maintain proprioceptive mediation and a mechanism for masticatory force vectors that favor bone retention over bond resorption. The degree of stability enhancement and denture retention from retained roots varies with the design and environment of the prosthesis. This article reviews various aspects of removable partial over-denture use.
作为全口义齿的替代方案，覆盖义齿已被公认为是晚期牙列患者的一种可靠治疗方式。通过利用天然牙根及其牙周结构来辅助支撑，覆盖义齿可维持本体感觉调节以及咀嚼力向量机制，有利于骨保留而非骨吸收。保留牙根所带来的稳定性增强程度和义齿固位效果因修复体的设计和环境而异。本文综述了可摘局部覆盖义齿使用的各个方面。
