摘要： Method and/or apparatus embodiments for 3-D cephalometric analysis of a patient according to the application can display reconstructed volume image data from a computed tomographic scan of a patient's head including segmented dentition elements having an initial arrangement from one or more 2D/3D views; can compute and display a plurality of cephalometric parameters for the patient according to the reconstructed volume image data; then use the patient specific cephalometric parameters and population biometry data, to identify one or more maxillofacial/dental abnormalities; and compose patient specific treatment plans to correct selected dentition abnormalities using maxillofacial/dental structure, which can be composed in a final tooth arrangement in a final virtual CT volume. One or more aligners can be generated to incrementally move dentition from the initial arrangement to the final tooth arrangement.

摘要： A computer-implemented method for generating a digital model of an individual intraoral component from a digital model of a patient's dentition obtains a 3-D digital mesh model of the patient's dentition and performs automatic tooth component segmentation operation on the obtained mesh model. Automated segmentation results display. Interactive segmentation of the automated segmentation results is performed according to an operator instruction. Segmentation results are displayed and stored.

摘要： A computer-implemented method for generating one or more segmented 3-D teeth models obtains a 3-D mesh model of a patient's dentition and executes a first segmentation procedure on the obtained 3-D mesh model, displaying one or more segmented teeth from the 3-D mesh model. At least one of the one or more segmented teeth is recorded according to operator instruction and removed from the 3-D mesh model to form a modified 3-D mesh model. A repeating sequence identifies a modified segmentation procedure, executes the modified segmentation procedure on the modified 3-D mesh model, displays one or more segmented teeth from the modified 3-D mesh model, records at least one of the one or more segmented teeth, and removes the recorded at least one tooth from the modified 3-D mesh model. Recorded segmentation results are displayed, stored, or transmitted.

摘要： A method or computer program for forming a digital model of a patient's teeth. The method includes the steps of: obtaining a plurality of projection images acquired by scanning a negative impression of the patient's teeth using a computed tomographic imaging apparatus; generating, from the plurality of projection images, an air volume model of the air that surrounds the negative impression; defining a transition surface along edges of the air volume model that touch the negative impression; forming the digital model of the patient's teeth according to the defined transition surface; and displaying, storing, or transmitting at least a portion of the digital model of the teeth.
