摘要/Abstract

摘要： 目的随着数字化技术的普及应用和植入材料的改良,本团队利用浓缩生长因子（CGF）联合冲击法提升技术,通过改良上颌窦底提升同期植入种植体的手术方法,大大提高了上颌窦底提升的成功率,在增加提升高度的同时,也降低了上颌窦底黏骨膜穿孔的风险。方法本研究通过回顾性分析自2023年5月至2024年8月在深圳市口腔医院就诊的30例单牙缺失的临床病例数据,使用冲击法联合液压提升技术进行上颌窦底提升同期植入种植体,对比种植位点术前术后的上颌窦底黏骨膜厚度、提升的高度等,明确此改良技术的优势。结果临床分析数据表明按照改良方法的手术程序,上颌窦底黏骨膜的厚度前后对比无明显差异,而平均提升的高度达7.6 mm（P<0.001）。结论通过数字化导板辅助,联合冲击法和液压提升技术,可以使原本只能盲视下操作的手术变成能精准控制的术式,在保证不损伤上颌窦底黏骨膜的情况下,有效分离提升上颌窦底黏骨膜,植入骨替代材料并同期完成种植体的植入。本方法的成功率高,并且效果显著,可将手术流程标准化,便于临床的使用推广。

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.
