胶原蛋白海绵修补穿牙槽嵴上颌窦底提升中窦膜穿孔的回顾性研究
Retrospective study on collagen sponge repair of sinus membrane perforation during transcrestal sinus floor elevation
摘要
Abstract
Objective To evaluate the efficacy of collagen sponges in repairing maxillary sinus membrane perforations in transcrestal sinus floor elevation(TSFE).Methods A total of 30 patients(42 implants)who underwent TSFE in the Department of Stomatology at the First Affiliated Hospital of Dalian Medical University from September 2019 to September 2024 were enrolled in this retrospective analysis.Based on the occurrence of intraoperative perforation,the patients were divided into a perforation group(n=13)and a non-perforation group(n=29).Cone-beam computed tomography(CBCT)images were obtained and analyzed at baseline,immediately after surgery,and 6 months postoperatively to assess new bone height(NBH)and new bone height/implant protrusion length ratio(NBH/IPL).Results The perforation rate was 30.95%.Both groups achieved 100%implant retention at 6 months with no maxillary sinus infection observed.The perforation group exhibited a mean NBH of(2.22±0.61)mm and an NBH/IPL of 58.33%(42.08%,84.58%),both significantly lower than those of the non-perforation group(P<0.05).Type A and C perforation groups showed no statistically significant difference in bone formation compared to the non-perforation group(P>0.05),while the Type B perforation group exhibited significantly reduced bone formation(P<0.05).Conclusion Collagen sponges can partially seal TSFE sinus membrane perforations and maintain baseline bone formation,but such perforations still reduce bone formation volume.关键词
