Cone-beam dental computerized tomography has been introduced as a system geared towards maxillofacial imaging, which is gradually becoming a common tool within the dental industry. Segmentation of teeth from dental CT data is vital for a variety of computer-aided procedures such as dental implants, orthodontic planning and cosmetic surgeries. Teeth segmentations near soft tissue structures can help...
Dental caries is the infectious oral disease affecting people worldwide. Early dental caries detection helps to prevent caries progression by non-surgical methods and promote tooth remineralization. A simple method based on laser induced fluorescence spectrum with backscattered enhancement is proposed for the detection of initial caries on vitro teeth. Fluorescence spectra of carious erosion on different...
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...
In order to economize the labor time and increase the accuracy of dental restoration, an automated CAM system for NC tool path planning and generation is developed in this work. Compared with traditional methods, the proposed automated CAM system brings in a novel algorithm for model machining boundary extraction, an algorithm for multi-model path planning and an algorithm for tool path generation...
