摘要： 目的评价侧壁开窗上颌窦底提升同期种植窦嵴距对种植体留存率的影响。方法回顾性队列研究2012年4月至2022年4月在深圳市友睦口腔门诊部就诊的上颌后牙区种植骨量不足的患者,行侧壁开窗上颌窦底提升、植入去蛋白牛骨矿物质并同期行种植体植入,术后6个月二期修复。依据剩余窦嵴距分为组1（<3 mm）及组2（≥3 mm）,评价术后并发症、种植体留存率及边缘骨吸收状况。结果共124例患者,136侧侧壁开窗上颌窦底提升,植入252颗种植体,平均随访时间（58.1±15.8）个月。组1种植体留存率91.59%,组2种植体留存率93.10%,2组间无统计学差异;27侧发生了上颌窦黏骨膜穿孔（19.85%）,穿孔与种植体失败率无显著相关。结论侧壁开窗上颌窦底提升同期种植是治疗上颌后牙骨高度不足的有效技术,剩余窦嵴距与种植体留存率无显著相关关系。

Abstract: Objective To evaluate the impact of subantral residual bone height (SRBH) on implant survival rates during simultaneous implant placement with the lateral window technique for sinus floor elevation. Methods A retrospective cohort study was conducted on patients treated at Shenzhen U-Dental Clinic between April 2012 and April 2022. These patients, with insufficient bone volume in the maxillary posterior region, underwent the lateral window technique for sinus floor elevation with simultaneous implant placement using bovine-derived inorganic bone graft material. Secondary prosthetic restoration was performed 6 months postoperatively. Patients were divided into two groups based on SRBH: Group 1 (<3 mm) and Group 2 (≥3 mm). Postoperative complications, implant survival rates, and marginal bone loss were evaluated. Results A total of 124 patients underwent 136 maxillary sinus surgeries with 252 implants placed. The mean follow-up period was 58.1±15.8 months. Implant survival rates were 91.59% in Group 1 and 93.10% in Group 2, with no statistically significant difference between the groups. Sinus membrane perforation occurred in 27 cases (19.85%), but it was not significantly associated with implant failure. Conclusion Simultaneous implant placement with the lateral window technique for sinus floor elevation is an effective treatment for insufficient bone height in the maxillary posterior region. There is no significant correlation between SRBH and implant survival rates.
