摘　　要：目的分析和评价下颌骨三维重建的效果其及影响因素,为以下颌骨三维重建为基础的相关研究和临床应用提供参考。方法利用CT扫描获取下颌骨标本的断层解剖信息并以DICOM格式输出,然后采用三维重建软件进行重建,大体观察重建效果后,利用软件以有关解剖标志为测量点,对下颌骨重建模型的下颌骨体厚度、下颌骨升支前后径进行测量,测量结果与下颌骨标本的相应测量结果进行比较。结果CT扫描空间分辨率高,下颌骨三维重建的效果良好,对比测量分析表明重建模型与下颌骨标本无明显差异。结论基于CT扫描的下颌骨三维重建能满足相关科研和临床应用的需要。Objective To analyze and evaluate the effect of three-dimensional reconstruction of mandible and its relevant influencing factors, in order to provide references for research and application based on three-dimensional reconstruction of mandible. Methods Layered anatomic information of a mandible specimen was collected by CT scanning and then three-dimensional reconstruction of the mandible was carried out by software. Anterior-posterior dimension of the ramus and the thickness of the corpus of both the three-dimensional reconstructed model and the specimen of the mandible were measured and compared to evaluate the effect of three-dimensional reconstruction. Results High resolution of three-dimensional reconstruction was gained by CT scanning. Statistical analysis showed that there had been no difference of the measurement between the three-dimensional reconstructed model and the specimen. Conchusion Three-dimensional reconstruction of the mandible based on CT scanning could get good reconstruction effect and could meet the need of relevant research and clinical application that based on three-dimensional reconstruction of the mandible.
