Abstract: According to some embodiments of the invention, it is provided a method of generating a 3D model of a first denture and of a second denture comprising:



x-ray scanning the first and the second dentures in occlusion conditions to obtain a set of data;
generating, from the obtained set of data, a 3D image of the first and the second dentures in occlusion conditions, the generated 3D image comprising voxels;
classifying each of voxels of the generated 3D image as belonging to the first denture, the second dentures, or space between the first and the second dentures; and
generating, from the classified voxels, a 3D model of the first denture and of the second denture,

wherein classifying a voxel of the generated 3D image is based on characteristics of neighboring voxels in the generated 3D image, according to an iterative analysis of voxels from neighbor to neighbor.

Abstract: Method for allowing patient review of virtual restoration element in video of dentition. At least one restoration element for at least one selected tooth of patient dentition is designed using 3D dentition models based on CAD/CAM techniques. Then, real-time video of the patient's dentition including the at least one selected tooth is displayed, where the video orientation is controlled by the patient. Then, the displayed real-time video of the dentition is modified in real-time including the at least one selected tooth to show the at least one restoration element registered to physical teeth in the real-time video of dentition to replace the at least one selected tooth in the modified displayed real-time video of the dentition.

Abstract: A method and system for fabricating a dental appliance for orthodontic treatment. The method comprises the steps of obtaining three-dimensional dental data from a patient scan, locating initial tooth positions, generating optimal arch forms, and determining a digital model for fabricating an orthodontic aligner with additive device. The system comprises a scanning apparatus to acquire three-dimensional dental data, and a computer apparatus programmed with instructions for generating optimal arch forms, and determining a digital model for fabricating an orthodontic aligner with additive device.
