The results on 32 consecutive patients, who underwent bone grafting prior to implant surgery, are presented. The grafts were taken from the horizontal part of the mandible, including the full height of the buccal cortico-cancellous plate and were used to reconstruct alveolar defects or to augment sinus floors. 3-5 months postoperatively, 99 implants were inserted in 43 onlay grafts and in 17 sinus floor augmentations. The follow-up ranged from 2-6 years post implant insertion. Parameters examined included: healing of donor site and bone grafts, implant survival, peri-implant condition, donor site morbidity and patient satisfaction. This study indicates that with one full height ramus graft, alveolar defects comprising a bicuspid-molar area, can be augmented. The grafted volume is also sufficient to augment one sinus floor. The implant survival rate (99%) compares well with studies using iliac crest or skull bone. Postoperative complaints were minimal, resulting in extremely high patient satisfaction (97%).
本文介绍了 32 例连续患者的研究结果，这些患者在接受种植术前进行了骨移植。移植骨取自下颌骨的水平部分，包括颊侧皮质-松质板的全长，并用于重建牙槽骨缺损或增加窦底。术后 3-5 个月，在 43 例骨块移植和 17 例窦底增高术中植入了 99 枚种植体。植入后随访时间为 2-6 年。检查的参数包括：供区和移植物的愈合情况、种植体存活率、种植体周围状况、供区发病率和患者满意度。本研究表明，使用全长颊侧升支骨块可以增加包括双尖牙-磨牙区的牙槽骨缺损。移植骨量也足以增加一个窦底。种植体存活率（99%）与使用髂嵴或颅骨的研究结果相当。术后并发症很少，患者满意度极高（97%）。
