摘要: 目的:通过螺旋CT数据的三维重建与测量,评估用含量为100% DBBM无机牛骨(Bio-Oss)充填材料进行上颌窦提升后提升区组织的体积稳定性。方法:对12例用100% DBBM进行上颌窦外提升一期植骨术的患者分别于术后2周与6个月行提升区的螺旋CT扫描,将CT数据通过SurgiCase CMF5.0软件进行三维重建与测量,通过自身前后对照观察充填区体积的变化。数据计算由Stata10软件包完成。结果:充填物总体积平均减小19.40%。其中,颊腭向最宽处平均减少0.29%,近远中向最宽处平均减少5.87%,垂直向最高处平均减少14.32%。结论:DBBM在术后6个月内有一定的体积收缩,以垂直向最为显著。

Abstract: PURPOSE: The objective of present study was to assess the dimensional stability of the grafting material DBBM (Bio-oss )after maxillary sinus floor augmentation with spiral computed tomography (SCT) scans and 3D reconstruction. METHODS: Two postoperative SCT scans were available from 12 patients who had undergone maxillary sinus lift procedures. CT scan was taken at 2 week after surgical intervention and 6 months later, respectively. A total of 12 maxillary sinuses were augmented with 100% DBBM before implant insertion by lateral antrostomy in a staged approach. The augmentation volume was calculated using the SurgiCase CMF5.0 software. Data were calculated by Stata10 software package. RESULTS: The mean volume of the graft was reduced by 19.40%. Specifically, the reduction reached 0.29%in the buccal-palatal direction, 5.87% in the mesial-distal dimension, and 14.32% in vertical dimension. CONCLUSIONS: This study confirmed that the volume of DBBM has a certain amount of reduction within 6 months after sinus floor augmentation. The reduction in vertical direction is most severe.
