目的 :探讨在上颌窦区骨量不足3 mm的情况下,进行上颌窦底提升术并植骨同期将种植体植入的临床效果。方法:选择复旦大学附属中山医院和静安区牙病防治所2012年4月1日—2015年12月31日上颌后牙缺失患者56例,剩余牙槽骨高度均小于3 mm,术中行上颌窦底提升术并植骨,同期将种植体植入。术后3、6、12个月定期随访,分析及评估术后愈合效果及骨结合情况。结果:56例患者共植入72颗种植体,随访期间,种植体与周围骨组织结合良好,种植体稳定。术后6个月行种植修复,均能正常行使咀嚼功能,牙龈无形态、色泽异常,无并发症发生,手术成功率为100%。结论:对于上颌窦底骨量不足3 mm的患者,术中行上颌窦底提升术并植骨同期将种植体植入,也能取得良好的治疗效果。
OBJECTIVE: To investigate the clinical effect of maxillary sinus floor elevation and bone graft implantation in the same period when the maxillary sinus bone mass is less than 3 mm. Methods: 56 cases of maxillary posterior teeth missing from Zhongshan Hospital Affiliated to Fudan University and Dental Prevention Station of Jing’an District from April 1, 2012 to December 31, 2015, the remaining alveolar bone height were less than 3 mm. The maxillary sinus At the end of lifting and bone graft, the implant will be implanted over the same period. Regular follow-up was performed 3, 6 and 12 months after operation to analyze and evaluate the effect of postoperative healing and bone union. Results: A total of 72 implants were implanted in 56 patients. During the follow-up period, the implants were well integrated with the surrounding bone tissue and the implants were stable. 6 months after implantation line repair, can exercise the normal masticatory function, no shape of gingival, abnormal color, no complications, surgical success rate was 100%. CONCLUSIONS: For patients with less than 3 mm maxillary sinus floor, maxillary sinus lift and bone graft during implantation during the same period can achieve good therapeutic effect.
