The goal of prosthodontics is to provide a functional prosthesis to restore aesthetics, functions, and masticatory efficiencies. Tooth-supported overdentures are one of the treatment options for removable dentures. This article aims to discuss the advantages and disadvantages of tooth-supported overdentures and the principles of using various overdenture attachments, including non-attachment overdentures. The common treatment options in preparing the overdenture abutment are either with or without abutment coping with or without attachment systems, which were discussed and illustrated. A range of tooth-supported overdenture systems were addressed, from low to high financial implications and treatment complexities. The clinician can choose a system that best fits the patient's condition and expectations. This allows clinicians to decide and consider tooth-supported overdentures as a treatment option before full edentulism. A well-executed tooth-supported overdenture ensures the preservation of alveolar bone, optimizes patient satisfaction in denture treatment, and eventually improves the patient's adaptation when transitioning to complete dentures.
口腔修复学的目标是提供一个功能性修复体，以恢复美观、功能和咀嚼效率。牙支持式覆盖义齿是可摘局部义齿的治疗选择之一。本文旨在讨论牙支持式覆盖义齿的优缺点以及使用各种覆盖义齿附着体的原则，包括无附着体覆盖义齿。文中讨论并举例说明了在制备覆盖义齿基牙时常见的治疗选择，即有无基牙帽以及有无附着系统。文中介绍了一系列牙支持式覆盖义齿系统，从低到高的经济成本和治疗复杂性。临床医生可以选择最适合患者病情和期望的系统。这使临床医生能够在患者完全无牙之前就将牙支持式覆盖义齿作为一种治疗选择进行决策和考虑。一个执行良好的牙支持式覆盖义齿可确保牙槽骨的保存，优化患者对义齿治疗的满意度，并最终提高患者向全口义齿过渡时的适应性。
