For many years the technique of osseointegration in the anterior part of the mouth has been used with predictable success to treat completely edentulous arches. This prospective study was begun in the mid-1980s to adapt this technique to the partially edentulous situation in this same anterior region of both the maxillae and mandible. Ninety-four implants were placed into 34 edentulous areas in 30 partially edentulous patients. Forty-seven (94%) of the 50 implants placed into maxillae and 39 (88.6%) of the 44 placed into mandibles remain in function after periods of loading ranging from 2 to 8 years (mean 4.7 years). This average success rate of 91.5% was sufficient to ensure a 100% resolution of the selected patients' maladaptive prosthodontic experiences. These results suggest that past experiences with osseointegration in the anterior of the completely edentulous mouth can be replicated in patients with anterior partial edentulism.
多年来，口腔前部骨结合技术已被用于治疗全口无牙弓，且成功率可预测。这项前瞻性研究始于20世纪80年代中期，旨在将该技术应用于上颌骨和下颌骨同一前部区域的部分牙列缺失情况。在30名部分牙列缺失患者的34个无牙区植入了94颗种植体。在上颌植入的50颗种植体中有47颗（94%），在下颌植入的44颗中有39颗（88.6%），在2至8年（平均4.7年）的加载期后仍在发挥功能。91.5%的平均成功率足以确保所选患者的不良修复体验得到100%的解决。这些结果表明，在全口无牙的前部进行骨结合的既往经验可以在部分牙列缺失的前部患者中复制。
