CGF联合冲击法在穿牙槽嵴上颌窦底提升中的应用
Application of CGF combined with hydraulic pressure technique in transcrestal maxillary sinus floor elevation
摘要
Abstract
Objective With the widespread application of digital technology and advancements in implant materials,our team utilized concentrated growth factors(CGF)combined with the osteotome condensing and hydraulic pressure elevation technique to modify the surgical protocol for simultaneous implant placement during maxillary sinus floor elevation.This approach significantly increased the success rate of sinus augmentation,achieving greater elevation heights while reducing the risk of Schneiderian membrane perforation.Methods This retrospective study analyzed clinical data from 30 patients with single-tooth loss in the posterior maxilla treated at Shenzhen Stomatological Hospital between May 2023 and August 2024.All patients underwent sinus floor elevation with simultaneous implant placement using osteotome condensing combined with hydraulic pressure elevation.The Schneiderian membrane thickness and the achieved elevation height at the implant sites were compared preoperatively and postoperatively.Results Data showed no significant difference in Schneiderian membrane thickness before and after the procedure,while the mean elevation height was 7.6 mm(P<0.001).Conclusion With the aid of a digital surgical guide,the combined use of osteotome condensing and hydraulic pressure elevation transforms a procedure previously performed blindly into a precisely controlled surgical technique.This method enables effective and safe separation and elevation of the Schneiderian membrane without damage while allowing for simultaneous placement of bone substitute material and dental implants.The modified protocol demonstrates a high success rate and significant clinical effectiveness and can be standardized to facilitate broader clinical application.关键词
