摘　　要：目的:比较三维激光扫描法和多基线数字近景摄影测量法在牙颌模型的三维测量中的差异方法采用20副标准理想颌牙颌石膏模型,由同一实验者在不同时间段,分别用两种方法进行三维成像和建模,并在计算机上重复两次标注测量标志点,测量设定项目数据,采用SPSS10.0统计学软件对测量数据进行对比分析。结果:两种测量方法的牙颌模型测量结果未见统计学差异(P<0.05)。结论:多基线数字近景摄影测量法和三维激光扫描法均可满足牙颌模型的三维测量临床需求。虽然,激光扫描法精度上略高于多基线数字近景摄影测量法,但多基线数字近景摄影测量法所需设备少、价格低,更利于基层医院和口腔诊所普及使用。Objective： Comparison of 3D laser scanning method and multi - baseline digital close - range photogrmmnetry method in three - dimensional measuring dental model. Method： Using 20 pairs of standard ideal jaw dental plaster model, by the same in different time, two methods were used for 3D imaging and modeling, and the computer is repeated two timesannotation measure point, measure project data, comparative analysis of the measured data using SPSS10.0 statistical software. Resuh： Dental model measurement results of two methods for measurement of no statistical difference （P 〉 0.05）. Conclusion： Multi- baseline digital close - range photogrammetry and 3D laser scanning method can meet the clinical needs of three- dimensional measuring dental model. Although, the accuracy of laser scanning method was higher than that of multi - baseline digital close - range photogrammetry, but digital close - range photogrammetry method multiple baseline needs less equipment, low price, more conducive to the grass- roots hospitals and dental clinic popularization.
