While considerable data have been published on the use of the osseointegration technique in the anterior region of the edentulous mouth, there remains scant information on its success in the posterior areas of either the maxillae or mandible. This prospective study was begun in the mid-1980s to test the effectiveness of this technique in the treatment of partially edentulous posterior areas of the maxillae and mandible, and in situations where the implant-supported prosthesis carries a significant portion of the total occlusal load. One hundred five implants were placed into 46 edentulous areas in 35 patients. After periods of loaded service ranging from 2.6 to 7.4 years (mean 5.2 years), of the 41 implants placed in maxillae, 40 (97.6%) remain in function, and of the 64 placed in mandibles, 59 (92.2%) remain in function. The overall implant survival rate of 94.3% suggests that partially edentulous areas in the posterior zones of either arch can be treated prosthodontically using osseointegrated implants with predictable success.
虽然关于骨结合技术在无牙颌前部区域的应用已发表了大量数据，但关于其在上颌或下颌后部区域应用成功的信息仍然很少。这项前瞻性研究始于20世纪80年代中期，旨在测试该技术在治疗上颌和下颌部分无牙的后部区域以及种植体支持的修复体承担大部分总咬合负荷情况下的有效性。在35名患者的46个无牙区域植入了105颗种植体。在经历了2.6至7.4年（平均5.2年）的负载使用期后，在上颌植入的41颗种植体中，40颗（97.6%）仍在发挥功能，在下颌植入的64颗中，59颗（92.2%）仍在发挥功能。94.3%的总体种植体存活率表明，使用骨结合种植体进行修复治疗，牙弓后部区域的部分无牙区可取得可预测的成功。
