The purpose of this retrospective study was to evaluate the success rate of implants and the amount of sinus augmentation using the flapless hydrodynamic piezoelectric internal sinus elevation (HPISE) technique with autologous concentrated growth factors (CGF) alone.
A total of 11 maxillary sinuses were augmented using the HPISE technique through the flapless transcrestal approach. Sixteen implants (average 11.38 mm in length and 4.83 mm in diameter), with 2 different surfaces, were placed simultaneously with CGF alone. Plain panoramic radiograms and cone-beam computed tomograms (CBCT) were taken in all patients to evaluate the sinus augmentation preoperatively and postoperatively.
The sinus membranes were successfully elevated, averaging 13.95 ± 6.61 mm in immediate postoperative CBCT without any iatrogenic perforation. After an average 23.8 weeks, the average bone gain above the sinus floor was 8.23 ± 2.88 mm in the axial aspect of CBCT. No complications were recorded in any patients during the follow-up period.
The flapless transcrestal approach to the sinus augmentation using the HPISE technique with autologous CGF alone could be an alternative to the lateral approach, even at severely resorbed edentulous posterior maxilla with insufficient bone height.
本回顾性研究的目的是评估仅使用自体浓缩生长因子（CGF）的无瓣水动力压电式上颌窦内提升（HPISE）技术的种植成功率及上颌窦提升量。
通过无瓣经牙槽嵴入路，共对上颌11个窦采用HPISE技术进行提升。同时仅使用CGF植入16枚种植体（平均长度11.38mm，直径4.83mm），种植体有2种不同表面。对所有患者术前及术后均拍摄全景平片和锥形束计算机断层扫描（CBCT）以评估上颌窦提升情况。
术后即刻CBCT显示，上颌窦膜成功提升，平均提升高度为13.95±6.61mm，无任何医源性穿孔。平均23.8周后，CBCT轴位显示上颌窦底上方平均骨增量为(8.23\pm2.88mm)。随访期间所有患者均未记录到并发症。
即使在骨高度不足的严重吸收的上颌后牙区无牙颌，仅使用自体CGF的HPISE技术经无瓣经牙槽嵴入路上颌窦提升术也可作为外侧入路的替代方法。
