摘要： 目的:研发基于CBCT容积数据的体绘制可视化技术,并对拟行上颌磨牙区种植的患者的种植区域进行三维演示,以期提高对此类患者种植区骨量及上颌窦情况术前评估的直观性。方法:将经临床筛选的13例上颌后牙种植患者使用CBCT扫描所获得的原始DICOM数据分别导入NNT 2.19(J.MoritaManufacturing Corp.)软件及本项目组研发的三维可视化软件(TooMax 1.0),分别测量牙槽嵴顶至上颌窦底的高度(H1)、种植区牙槽骨颊腭向宽度(H2),对两种软件测量的骨量进行统计学分析,同时在TooMax中使用体绘制可视化技术显示上颌窦形态及位置以及二维骨量测量值在牙槽骨内的空间位置。结果:用两种软件测量的13例上颌后牙种植患者的骨量测量不具有显著性差异,同时可视化技术可以将不同测量值在上颌骨内的三维空间位置实时显示及变换,便于医患交流,并辅助种植方案的设计。结论:体绘制可视化技术提升了CBCT技术对种植骨量评估的直观性,具有一定的种植模拟的效果,有助于实现可视化临床治疗目标。

Abstract: Objective: To develop a volume rendering visualization software based on CBCT volume data, to three-dimensionally demonstrate the maxillary molar region, and to improve the visuality of pre-surgery assessment of alveolar bone and maxillary sinus for implantation in maxillary molar regions. Methods: The original CBCT data in DICOM format of 13 maxillary molar implant cases were imported into both NNT 2.19 software (J.Morita Manufacturing Corp.) and the software TooMax 1.0 developed by our project team, the heights from alveolar crest to the floor of maxillary sinus (H1) and the buccal-palatal widths (H2) were measured in both softwares. The measurements were analyzed. Maxillary sinus and the two-dimensional lengths were demonstrated in the three-dimensional volume rendering models. Results: No significant difference was found between the two softwares, and the three-dimensional and real-time demonstrations of the measurements could facilitate communications between doctors and patients and aid in designing of implantation. Conclusion: Volume rendering enhances the visuality of CBCT technology and can simulate implantation to some extent, which is conducive to achieve visualization in clinical treatment.
