Forty-three patients with severely resorbed maxillae who had been referred for implant treatment were assigned to one of three treatment groups: bone grafting and implant placement (graft group); modified implant placement but no bone grafting (trial group); or optimized complete dentures (no-implant group). Sixteen, 20, and 7 patients, respectively, were assigned to the three groups. At the 1-year follow-up, 10% of the implants had been lost. Only a few of the failures (3/22) occurred after prosthesis placement. The cumulative success rates were 83% in the graft group and 96% in the trial group. A substantial reduction of the grafted bone, especially of the onlay grafts, occurred in many patients. During the period from prosthesis connection to the 1-year follow-up, marginal peri-implant bone loss was on average 0.5 mm. Despite the often demanding procedures involved, all but one patient in each implant group said that they would undergo the treatment again. Most patients were very satisfied with the treatment outcome and their improved masticatory ability. Those who had renounced implant treatment appeared modestly adapted to their optimized dentures, but reported retention problems and less satisfaction with mastication.
43 名因上颌骨严重吸收而前来接受种植治疗的患者被分配到三个治疗组之一：骨移植并植入种植体（移植组）；改良种植体植入但不进行骨移植（试验组）；或优化全口义齿（非种植组）。分别有 16 名、20 名和 7 名患者被分配到这三个组。在 1 年的随访中，10% 的种植体出现丢失。只有少数失败病例（3/22）发生在义齿安置之后。移植组的累积成功率为 83%，试验组为 96%。许多患者出现了移植骨的大量减少，尤其是覆盖式移植骨。在从义齿连接到 1 年随访期间，种植体周围边缘骨丢失平均为 0.5 毫米。尽管手术过程往往要求很高，但每个种植组中除了一名患者外，其他所有患者都表示愿意再次接受该治疗。大多数患者对治疗结果和咀嚼能力的改善非常满意。那些放弃种植治疗的患者似乎对他们优化后的义齿适应程度一般，但报告了固位问题以及对咀嚼的满意度较低。
