摘要:

目的 评价上颌窦解剖因素(上颌窦宽度、上颌窦角度、剩余骨高度)对经牙槽嵴顶上颌窦底提升术骨移植材料稳定性的影响。方法 纳入42例行经牙槽嵴顶上颌窦底提升术并同期种植的患者,共计60个上颌窦底提升位点,骨移植材料采用自体骨与小牛骨混合物。术前、术后当天及术后6个月采用锥形束CT(CBCT)进行指标参数的测量,采用Pearson相关分析评价上颌窦宽度、上颌窦角度、剩余骨高度3种解剖因素与术后6个月种植体根端骨吸收量之间的相关性。结果 窦底剩余骨高度为(4.46±1.55)mm,上颌窦宽度为(13.86±2.71) mm,上颌窦角度为78.09°±10.27°。相关分析结果显示,上颌窦宽度与根端骨吸收量之间存在显著的正相关关系(P<0.01),上颌窦角度与根端骨吸收量之间存在显著的正相关关系(P<0.01)。剩余骨高度与根端骨吸收量之间无相关关系(P>0.05)。结论 上颌窦宽度、上颌窦角度与根端骨吸收量之间存在正相关关系。

Abstract:

Objective To investigate the effect of three anatomical parameters (maxillary sinus width, maxillary sinus angle, and residual bone height) on the outcomes of transcrestal sinus lift with simultaneous implant placement. Methods A total of 60 maxillary sinuses in 42 patients were included in this study. All patients were treated with transcrestal sinus lift procedure associated with simultaneous implant placement using a composite graft material of autogenous bone and Bio-Oss. For each patient, beam computed tomography (CBCT) scans were performed preoperatively, immediately after surgery, and 6 months after surgery. The parameters were measured on the preoperative and postoperative CBCT images. The correlation of three anatomical parameters with graft resorption was analyzed using Pearson’s correlation test. Results The average residual bone height was (4.46±1.55) mm. The average width of maxillary sinus was (13.86±2.71) mm. The average sinus angle was 78.09°±10.27°. A significant positive correlation was observed between maxillary sinus width and graft resorption (P<0.01). A positive association was also found between sinus angle and graft resorption (P<0.01). Conclusion The findings show that graft bone resorption in elevated sinus has a positive correlation with the sinus width and sinus angle.
