  • SMILE TREATMENT PLANNING SYSTEMS AND METHODS
    Publication number: 20220054232
    Abstract: Smile treatment planning systems and methods are described herein. One method for adjusting an image of a smile may generally comprise receiving a three-dimensional (3D) digital model of a dental arch of a patient, receiving a digital facial image of the patient which includes an image of one or more teeth of the patient when smiling, registering the 3D digital model to the one or more teeth of the patient from the digital facial image, correcting the 3D digital model for scale and distortion to create a corrected 3D digital model, and overlaying the corrected 3D digital model onto the digital facial image.

  • System and method for image segmentation in generating computer models of a joint to undergo arthroplasty
    Patent number: 8483469
    Abstract: Systems and methods for image segmentation in generating computer models of a joint to undergo arthroplasty are disclosed. Some embodiments may include a method of partitioning an image of a bone into a plurality of regions, where the method may include obtaining a plurality of volumetric image slices of the bone, generating a plurality of spline curves associated with the bone, verifying that at least one of the plurality of spline curves follow a surface of the bone, and creating a 3D mesh representation based upon the at least one of the plurality of spline curve.
