Approximately one-third of Americans older than 65 years of age are fully edentulous, requiring replacement of missing teeth. While the conventional denture may meet the needs of many patients, others require more retention, stability, function and esthetics, especially in the mandible. The implant-supported prosthesis is an alternative to the conventional removable denture.
This article describes the strengths of the implant-supported mandibular overdenture. The authors also outline the risks of this approach. They performed a review of recent literature to summarize the reported success rate of implants used to support a mandibular overdenture.
The literature review indicates that implants placed in the anterior mandible (anterior to the foramen) have a success rate better than 95 percent. Patients have reported a high degree of satisfaction with the implant-supported overdenture.
The literature indicates that implant-supported overdentures in the mandible provide predictable results with improved stability, retention, function and patient satisfaction compared with conventional dentures. Implants placed in the anterior mandible have a success rate equal to or greater than 95 percent.
When planning treatment for patients with edentulous mandibles, clinicians should consider the implant-supported prosthesis.
65岁以上的美国人中约有三分之一全口无牙，需要镶复缺失的牙齿。虽然传统假牙可能满足许多患者的需求，但其他患者需要更好的固位、稳定性、功能和美观性，尤其是在下颌。种植体支持的修复体是传统可摘假牙的一种替代方案。
本文描述了种植体支持的下颌覆盖义齿的优点。作者还概述了这种方法的风险。他们对近期文献进行了综述，以总结用于支持下颌覆盖义齿的种植体的报道成功率。
文献综述表明，种植于下颌前部（孔前方）的种植体成功率超过95%。患者对种植体支持的覆盖义齿满意度很高。
文献表明，与传统假牙相比，下颌种植体支持的覆盖义齿能提供可预测的结果，稳定性、固位、功能和患者满意度均有所提高。种植于下颌前部的种植体成功率等于或大于95%。
在为无牙下颌患者制定治疗计划时，临床医生应考虑种植体支持的修复体。
