    摘要： 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.

    摘要： A method for segmenting a 3D model image of a patient's dentition obtains a first 3D model image of the patient dentition and obtains a first segmentation of the first 3D model image, wherein the first segmentation provides at least a tooth surface contour and a tooth label for one or more teeth of the first 3D model. A second 3D model image of the patient dentition is obtained. Each segmented tooth surface contour of the first 3D model is registered to corresponding tooth surface contour of the second 3D model. A second segmentation of the second 3D model image is obtained according to the registered tooth surface contour, wherein the second segmentation similarly provides at least tooth surface contour and a tooth labeling for one or more teeth of the second 3D model image. The segmented second 3D model image is displayed, transmitted, or stored.

    摘要： A method for registering a 3D mesh and a 3D volume image of a patients teeth obtains a 3D volume image of the patients teeth in an occlusion position, the 3D volume image containing at least one jaw portion. A contour surface is generated to form the 3D mesh corresponding to at least one of lingual and vestibular surfaces of the teeth from the 3D volume image. A registered mesh is provided in an occlusion position, the registered mesh having at least one of the vestibular and lingual surfaces. The registered mesh is registered with the generated contour surface content and displayed with the 3D volume image.
