摘要
目的:建立一种新的确立三维数字化牙颌模型咬合关系的方法。方法:单独扫描上下颌模型,获得单独的数字化牙颌模型,扫描正中颌位的上下颌模型,获得三维数字化咬合记录,利用Rapidform 2006软件中的三维配准方法将单独上下颌模型导入到咬合记录数据所在坐标系下。结果:上下颌单独数字化模型与数字化虚拟咬合记录重叠较好。结论:该方法较好地实现了在三维虚拟空间内上下颌咬合关系的确立。
Objective:To introduce a novel method,it be applied to establish the occlusion of 3D digital dental cast.Method:The upper and lower casts were scanned individually.The upper and lower casts were scanned together as the digital occlusion record.The upper and lower digital casts were overlapped on the digital occlusion record.Result:The upper and lower digital casts were overlapped with the digital occlusion record very well.Conclusion:The method was able to accurately established the digital occlusion.
