Results of studies have shown that a single implant mandibular overdenture significantly increases the satisfaction and quality of life of patients with edentulism. The single implant-retained overdenture has the additional advantage of being less expensive and invasive than a 2-implant supported overdenture but has a high incidence of fracture of the acrylic resin base at the point of the implant. The treatment, design, and fabrication of a metal-reinforced single-implant mandibular overdenture with the Locator attachment as a retention device is described.
研究结果表明，下颌单种植体覆盖义齿显著提高了无牙颌患者的满意度和生活质量。与 2 个种植体支持的覆盖义齿相比，单种植体保留的覆盖义齿具有成本更低、侵入性更小的额外优势，但种植体部位的丙烯酸树脂基的骨折发生率较高。本文介绍了使用Locator 附着体作为固位装置的金属增强型下颌单种植体覆盖义齿的治疗、设计和制作。
