[3Dp1-2] A Study for Retrieving Teeth Gingival Margin from Three-Dimensional Digital Model
Curvature, Gingival margin, DBSCAN, Clear aligners, 3D point cloud
Gingival margin (GM) identifies the necessary portion when people manufacture clear aligners. In automatic manufacturing system, it is considered as a three-dimensional (3D) line which needs to be cut and separated. This study proposes a model analysis method which is able to determine the 3D coordinate points of the patient's gingival margin based on curvature information.
