The study aimed to assess the clinical results after osteotome technique to lift sinus floor, without graft materials in the residual bone height (RBH), below 8 mm.
Twenty-two patients aged from 19 to 70 years old in need of maxillary sinus floor augmentation were enrolled in this study. Preoperative and postoperative cone beam computerized tomography (CBCT) were taken to guide the surgery. Twenty-seven implants were inserted and followed clinically, another CBCT exam was taken at 6 months postoperatively. The diameter of the implants was 4.7 mm (SD 0.4 mm), the length was 10 mm (SD 1.0 mm). The average residual bone height was 6.7 mm (SD 1.2 mm).
No implants were lost after the surgery and the 2 years follow-up. There was no obvious marginal bone loss during the 6 months follow-up verified by CBCT. The mean bone gain at the implant sites was 2.5 mm (SD 1.5 mm).
The study verified the good and stable clinical result of the OSFE technique without using bone grafting materials when the RBH was only 4.1-8 mm.
本研究旨在评估在剩余骨高度(RBH)低于8mm时,采用骨凿技术提升上颌窦底且不使用植骨材料后的临床效果。
本研究纳入了22例年龄在19至70岁之间、需要进行上颌窦底提升的患者。术前和术后均进行锥形束计算机断层扫描(CBCT)以指导手术。共植入27枚种植体并进行临床随访,术后6个月时再次进行CBCT检查。种植体直径为4.7mm(标准差0.4mm),长度为10mm(标准差1.0mm)。平均剩余骨高度为6.7mm(标准差1.2mm)。
术后及2年随访期间无种植体丢失。CBCT证实,在6个月的随访期间无明显边缘骨吸收。种植位点的平均骨增量为2.5mm(标准差1.5mm)。
本研究证实,当RBH仅为4.1 - 8mm时,不使用骨移植材料的骨凿上颌窦底提升(OSFE)技术具有良好且稳定的临床效果。
