超声骨刀在上颌窦侧壁开窗提升种植术中的临床应用

Piezoelectric osteotomy for the lateral window technique of maxillary sinus elevation with dental implantation

目的：评价超声骨刀在上颌窦侧壁开窗提升牙种植术中应用的临床效果。方法：15例上颌后牙缺失患者，术前CBCT检查牙槽嵴顶距上颌窦底的骨量高度为3．0～6．5 mm，采用超声骨刀行上颌窦侧壁开窗提升术并同期植入19颗种植体，术后即刻CBCT观察上颌窦底黏膜、窦内情况及种植体植入情况，术后3天随访观察有无上颌窦黏膜破裂并发症状。结果：15例中无1例出现上颌窦黏膜破裂，术后CBCT检查所有患者上颌窦窦底黏膜提升成功，无上颌窦底黏膜破损者，无患者出现上颌窦内液体渗出堆积。术后3天内随访，均无鼻腔出现血性分泌物或骨粉等异物排出现象。结论：采用超声骨刀行上颌窦侧壁开窗提升牙种植术，可以大大减少种植手术的时间，降低了手术并发症的风险。

Objective：To evaluate the clinical effect and technical advantages by applying piezoelectric osteotomy for the lateral window technique of maxillary sinus elevation with dental implantation. Method：15 cases with maxillary posterior tooth loss were selected,preoperative CBCT check the bone height from the alveolar crest to the maxillary sinus were 3.0~6.5 mm,applying piezoelectric osteotomy for the lateral window technique of maxillary sinus to elevat the bottom mucoss of maxillary sinus,19 implants were instantly embedded,CBCT observed immediately after the maxillary sinus mucosa and si-nus conditions,observe implant cases,observat the presence or absence of concurrent symptoms ruptured sinus mucosa after three days of follow-up. Result：None of the patients had intraoperative sinus membrane rupture,after checking all patients CBCT maxillary sinus mucosa enhance success,no significant damage in patients with maxillary sinus mucosa,no accumula-tion of fluid leakage in patients with maxillary sinus.Postoperative follow-up review of patients within three days,no nasal secretions or appear bloody discharge phenomena bone meal and other foreign matter. Conclusion：Applying piezoelectric osteotomy for the lateral window technique of maxillary sinus elevation with dental implantation,can greatly reduce the time of implant surgery and reduce the risk of surgical complications occur maxillary sinus window sidewalls,it has achieved well effect in clinical planting surgery of the patients need to the lateral window technique of maxillary sinus elevation,it is worth use in clinical practice widely.
