Abstract: 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.

Abstract: Method and/or apparatus embodiments for 3-D cephalometric analysis of a patient, acquires reconstructed volume image data from a computed tomographic scan of a patient's head including one or more dentition elements within the mouth of the patient, and computes one or more cephalometric parameters for the patient according to the reconstructed volume image data and the one or more dentition elements. One or more results generated from cephalometric analysis of the one or more computed cephalometric parameters can be stored, transmitted or displayed. The reconstructed volume image data is updated with 3D surface model from a subsequent optical scan of the patient's dentition and the one or more cephalometric parameters for the patient are re¬ computed based on the updated reconstructed volume image data.

Abstract: A method, executed at least in part by a computer, acquires three-dimensional data from scans of maxillofacial and dental anatomy of a patient and computes cephalometric values from the acquired three-dimensional data. The method processes the computed cephalometric values and generates metrics indicative of tooth positioning along a dental arch of the patient. The generated metrics are analyzed to calculate desired movement vectors for individual teeth within the dental arch. The calculated desired movement vectors are displayed, stored, or transmitted.

Abstract: A method for 3-D cephalometric analysis of a patient, executed at least in part on a computer processor, displays reconstructed volume image data from a computed tomographic scan of a patient's head from at least a first 2-D view and accepts an operator instruction that positions and displays at least one reference mark on the at least the first displayed 2-D view. One or more dentition elements within the mouth of the patient are segmented and cephalometric parameters for the patient computed and displayed according to data from the at least one reference mark and the one or more segmented dentition elements. Using the computed cephalometric parameters, one or more results indicative of maxillofacial asymmetry are computed and a graphical or text display energized to show the computed results indicative of asymmetry.

Abstract: A method for 3-D cephalometric analysis acquires reconstructed volume image data from a computed tomographic scan of a patient's head. The acquired volume image data simultaneously displays from at least a first 2-D view and a second 2-D view. For an anatomical feature of the head, an operator instruction positions a reference mark corresponding to the feature on either the first or the second displayed 2-D view and the reference mark displays on each of the at least first and second displayed 2-D views. In at least the first and second displayed 2-D views, one or more connecting lines display between two or more of the positioned reference marks. One or more cephalometric parameters are derived according to the positioned reference marks, the derived parameters are displayed.
