We have analysed retrospectively whether the less invasive zygomatic buttress graft is able to meet the dimensional and biological requirements of preimplant augmentation of bone. A total of 273 patients were treated by zygomatic buttress graft, of whom 42 (12 men and 30 women) met the criteria for inclusion. Intensity of pain was judged by a visual analogue score (VAS). Complications of grafting were evaluated, and dental implants were studied on clinical and radiographic examinations. The Schneiderian membrane was perforated in 13 cases (28%). The mean (SD) postoperative VAS was 3.1 (0.9) at the donor site. The mean (SD) follow-up after implant was 17(8) months. Two grafts were lost, one from initial dehiscence and later infection, and the other from infection. The mean (SD) marginal resorption of bone graft was 0.5 (0.7) mm. No implant was lost during the observation period. The zygomatic buttress graft meets the biological and dimensional requirements of augmentation of bone before implant that allows the dental implants to survive with satisfactory prosthetic rehabilitation.
我们进行了回顾性分析，以确定创伤较小的颧突支柱移植术是否能够满足种植前骨增量的尺寸和生物学要求。共有273例患者接受了颧突支柱移植术，其中42例（12例男性和30例女性）符合纳入标准。疼痛强度通过视觉模拟评分（VAS）进行判断。对移植的并发症进行了评估，并通过临床和影像学检查对牙种植体进行了研究。13例（28%）出现了上颌窦黏膜穿孔。供区术后VAS的平均值（标准差）为3.1（0.9）。种植后的平均（标准差）随访时间为17（8）个月。两块移植骨丢失，一块因最初裂开及随后感染，另一块因感染。骨移植的平均（标准差）边缘吸收为0.5（0.7）mm。观察期内无种植体丢失。颧突支柱移植术满足了种植前骨增量的生物学和尺寸要求，使牙种植体能够在满意的修复后存活。
