摘　　要：目的:获取牙尖交错位关系的上、下颌模型三维数据,并在计算机中重建牙尖交错位三维模型。方法:使用国产D.02L3DSCANNER扫描仪,设计一种扫描对颌模型的特定装置以获取上、下颌模型的三维数据,并在Surfacer软件中重建上、下颌三维模型。结果:成功获得分辨率高、牙体解剖形态清晰的牙尖交错位上、下颌模型的三维图形。结论:这是一种准确、简单、高效、可行的牙尖交错位模型的扫描方法,能够满足医疗、教学、科研的实际需要。Objective： To acquire the 3D point-cloud of the dental casts of intercuspal position and rebuild it in computer. Methods：Aspecial scanning method was used to acquire the point-cloud of dental cast by using the D. 02-L-3D SCANNER and rebuild the model by computer. Results： The method could acquire a 3D model with high resolving power and clear-cut dental anatomic configuration for the dental casts of intereuspal position. Conclusion： This is a viable method of scanning with many advantages, such as precision, simplicity , high efficiency. It could satisfy the requirements of clinical practice, teaching and scientific research.
