介绍和评价上颌后牙区牙槽骨吸收患者行上颌窦底抬高植骨一期种植术的方法和效果。６例（共９侧）Ⅰ～Ⅱ型上颌牙槽骨吸收患者，行上颌窦前外侧壁开窗后，分离并抬高窦底粘膜，常规植入２～３颗种植体，其中部分种植体用小型夹板固定，再于窦底种植体周充填自体骨、冻干骨、ＨＡ复合物。术后８～９月，Ｘ线检查骨生长愈合情况及种植体动度。结果８侧手术区一期愈合；８～９月后，种植体动度为０～－８，５例种植体与骨结合良好，３例牙槽骨质吸收２～３ｍｍ。结论上颌窦底抬高植骨一期种植术较好解决了上颌后牙区牙槽骨严重吸收而不宜种植的难题，值得临床推广应用。
To introduce and evaluate the method and effect of maxillary sinus floor elevation bone graft in patients with maxillary posterior alveolar bone resorption. 6 cases (9 sides) Ⅰ ~ Ⅱ maxillary alveolar bone resorption patients, the maxillary anterior lateral wall of the window after the separation and elevation of the sinus floor mucosa, conventional implantation of 2 to 3 implants, some of which implants Fix with a small splint, and then fill the autologous bone in the sinus implant, freeze-dried bone, HA complex. From August to September after operation, X-ray was used to examine the bone healing and implant movement. Results 8 cases of operation area were healed one by one. From August to September, the implant mobility was 0 ~ 8. 5 cases of implant were well combined with bone, and 3 cases received 2 ~ 3mm of alveolar bone. Conclusion The maxillary sinus floor elevation bone graft a period of better solution to the maxillary posterior teeth area alveolar bone serious absorption and should not be planted, worthy of clinical application.
