Dental implants as abutments for full-arch restorations are a well-documented treatment modality. This report presents a case in which the patient was treated initially with fixed restorations supported by either implants or natural teeth and subsequently treated with a removable implant/telescopic crown-supported overdenture. Advantages and disadvantages of each approach are described and discussed. While the fixed restoration resulted in a functionally satisfactory treatment outcome, the patient was displeased with the esthetic appearance. The main concern was the unnaturally long tooth shape necessary to compensate for the insufficient alveolar ridge height. Replacement of the existing restoration with an implant-supported removable overdenture led to a functionally and esthetically acceptable result. When deciding whether to use a fixed or removable implant-supported full-arch restoration, a multitude of factors must be considered. Due to the possible need for additional surgical steps to enhance the esthetic appearance surrounding fixed restorations, removable implant-supported partial dentures often are the better choice.
牙种植体作为全牙弓修复体的基牙是一种有充分文献记载的治疗方式。本报告介绍了一个病例，该患者最初接受了由种植体或天然牙支持的固定修复治疗，随后接受了种植体/套筒冠支持的可摘覆盖义齿治疗。描述并讨论了每种方法的优缺点。虽然固定修复在功能上取得了令人满意的治疗效果，但患者对美观效果不满意。主要问题是为了补偿牙槽嵴高度不足而需要的不自然的长牙形状。用种植体支持的可摘覆盖义齿替换现有的修复体，在功能和美观上都取得了可接受的结果。在决定是否使用固定或种植体支持的全牙弓可摘修复体时，必须考虑众多因素。由于可能需要额外的手术步骤来改善固定修复体周围的美观效果，种植体支持的可摘局部义齿通常是更好的选择。
