The purpose of this study is to demonstrate that autologous corticocancellous bone grafts from the ilium to the maxillary sinuses will mature (consolidate) and will support titanium cylindrical implants, which will in turn support a fixed prosthesis that will withstand the masticatory forces of a similar prosthesis in the mandible. The study was extended in order to determine whether bone changes had occured around the implants during the three years post-implantation.

这项研究的目的是证明自体 从髂骨到上颌窦的皮质松质骨移植将 成熟(巩固)并将支持钛圆柱形种植体， 将反过来支持一个固定的假体，它将承受 下颌骨中类似假体的咀嚼力量。这项研究是 扩展以确定周围是否发生了骨骼变化 种植体植入后三年内。
