上颌窦外提升及同期种植后临床研究

A Retrospective Study of Maxillary Sinus Augmentation and Simultaneous Implantation

摘要: 目的：评价上颌窦外提升加同期种植在后牙种植修复中的临床效果。方法：收集2018年12月~2021年12月青岛大学附属医院西海岸院区口腔种植科30例行上颌窦外提升加同期种植患者，共植入62颗种植体(均选择长度为11~12 mm种植体)，回顾性统计患者上颌窦成骨高度、术后3~6个月愈合及骨结合情况、牙龈健康状况、种植体稳定性及种植体存留率。结果：手术顺利，受植区平均牙槽骨高度3.7 ± 0.8 mm，术后上颌窦外提升高度为8.93 ± 1.39 mm，影像学检查结果显示96.8%的种植体与周围骨组织均结合良好，未发生种植体周围炎、种植体松动脱落或上颌窦炎等并发症，种植体均获得良好初期稳定性。结论：上颌窦外提升加同期种植短期内即获得良好临床效果，扩大后牙区种植的适应症，远期效果有待长期随访。

Abstract: Objective: To investigate the clinical and radiographic outcomes of the maxillary sinus floor eleva-tion technique and simultaneous dental implantation. Methods: The study population compared 30 patients in whom 62 implants (the length of the implants were 11~12 mm) were inserted with the maxillary sinus floor from Dec. 2018 to Dec. 2021, at the Department of Implantology in the Affili-ated Hospital of Qingdao University of West Coast District. The osteogenic height of maxillary sinus, the healing and bone union in 3~6 months after operation, and postoperative complications were retrospectively analyzed. Results: The operations were successful. The mean height of the alveolar process at the intended implant sites was 3.7 ± 0.8 mm, and the mean elevation of the sinus floor was 8.93 ± 1.39 mm. The surrounding bony tissues on imaging and 96.8% of them didn’t have com-plication, such as peri-implantitis, loose implant, maxillary sinusitis, etc. The implants obtained good initial stability. Conclusion: A good clinical effect is obtained in the short term after maxillary sinus lifting and implantation in the same time. Extending the indication in the posterior tooth area, long-term effect is expected to be followed-up for a long time.
