摘　　要：Survey lines are important features on the dental meshes for removable partial denture frameworks design, but few researche has been done by surveying digital models. This article describes a method for identifying survey line on dental meshes and displays survey line in real time. At the beginning, we segment tooth based on morphologic operators to get the tooth parts. The second step is to calculate the viewing direction perpendicular to the occlusal plane. Finally, we extract boundary points on 2D plane, thereby obtaining a survey line in the surveying direction. We have developed a module to demonstrate survey line in real time.Survey lines are important features on the dental meshes for removable partial denture frameworks design, but few researche has been done by surveying digital models.
