3D dental mesh repairing using template-based deformation

This paper proposes a mesh repairing method for segmented intra-oral scanned dental meshes. The method uses templates to provide additional dental information to repair missing parts on incomplete segmented dental meshes. The missing parts are determined by registration result using improved Iterative Closest Point (ICP) method, followed by a deformation-based repairing process. Using information from well-established templates, the repairing can provide reliable estimation for large missing area. The proposed method is automatic, simple, efficient and effective regarding different tooth shapes and missing parts. The conducted experiments demonstrate the effectiveness of the method.
