There has been an increasing interest in the use of implants for partially edentulous patients. This introduces other biomechanical situations than those experienced in completely edentulous patients. In a prospective multicenter study, 521 implants in 154 patients were loaded with 197 free-standing prostheses. The patients have been followed for 3 years. The cumulative success rate for the prostheses was 94.8% and for the implants it was 93.9%. Most of the lost prostheses were only supported by two implants. A frequent technical complication was fracture and loosening of gold screws, which was more frequent in prostheses supported by only two implants.
对于部分牙列缺损患者使用种植体的兴趣日益增加。这带来了与全口牙列缺失患者不同的生物力学情况。在一项前瞻性多中心研究中，154例患者中的521颗种植体上安装了197个独立式假体。对这些患者进行了3年的随访。假体的累积成功率为94.8%，种植体的累积成功率为93.9%。大多数丢失的假体仅由两颗种植体支持。常见的技术并发症是金螺丝断裂和松动，在仅由两颗种植体支持的假体中更为常见。
