Treatment of the atrophic maxilla using an onlay bone-grafting technique in combination with simultaneous insertion of endosteal implants (Branemark System) was performed in 17 patients. They were followed during a 3-year period. At the end of this period, 14 patients had stable bridges in use and one patient had an overdenture. Two patients had had to return to conventional dentures due to implant losses. The survival rate of the implants after 3 years use was 75%. It is concluded that, in spite of the implant losses, onlay bone grafting to the maxilla is a valuable method in cases of severe maxillary atrophy.
对17例患者采用覆盖式植骨技术并同时植入骨内种植体（Branemark系统）治疗萎缩性上颌骨。对他们进行了为期3年的随访。在随访期末，14例患者使用的固定桥稳定，1例患者使用覆盖义齿。2例患者因种植体丢失不得不恢复使用传统义齿。种植体使用3年后的存活率为75%。得出的结论是，尽管存在种植体丢失的情况，但对上颌骨进行覆盖式植骨在严重上颌骨萎缩病例中仍是一种有价值的方法。
