摘　　要：目的评估穿牙槽嵴顶四周剥离上颌窦底提升术临床应用效果。方法上颌后牙缺失剩余牙槽骨高度不足(<10mm)患者29例,共37个种植位点进行穿牙槽嵴顶四周剥离上颌窦底提升术。CBCT测量术前剩余牙槽骨高度及术后上颌窦底提升高度。结果 5例患者5个位点术中黏膜穿孔,位点黏膜穿孔发生率为13.51%。其余24例患者32个种植位点术前剩余牙槽骨高度从1.30~9.99mm,平均5.28±2.08mm,术后上颌窦底提升高度从4.61~13.47mm,平均9.62±2.09mm。黏膜未穿孔的24例患者32个位点术中同期植入种植体29颗,种植体长度从11.0~11.5mm,平均11.10±0.21mm。结论穿牙槽嵴顶四周剥离上颌窦底提升术对上颌窦底提升幅度大,可达到侧壁开窗上颌窦底提升术提升高度,扩大了穿牙槽嵴顶上颌窦底提升术适应证。黏膜穿孔是其主要并发症。Objective To evaluate the clinical applications of the transcrestal around detached sinus floor elevation technique（TADSFET）in the posterior maxillary region where the residual bone height（RBH） was less than 10 mm. Methods TADSFET was carried in 29 patients（37 implant sites）. CBCT was used to measure RBH preoperatively and the elevated height postoperatively. Results A total of 5 perforations of the sinus membrane were observed in 5implant sites（13.51%）. The RBH for the rest of 24 patients（32 implant sites）ranged from 1.30 to 9.99mm（averaged5.28±2.08mm）. The mean elevated height of the 32 implant sites was 9.62±2.09mm（ranged from 4.61 to 13.47 mm）. A total of 29 implants were placed in 24 patients（32 implant sites）with no perforations of the sinus membrane.The implant length ranged from 11 to 11.5mm. Conclusion Compared with traditional osteotome technique the TADSFET based on Chu Deguo Osteotome can achieve higher lift height.The TADSFET can be recommended when less than 4 mm of RBH was present.Perforation of the sinus membrane was the main complication when the TADSFET was used.
