METHODS FOR BUILDING TOOTH MODELS FROM PATIENT IMAGES AND ASSOCIATED SYSTEMS

Abstract: methods and systems for building a 3d model of teeth from a 2d image are provided, including: accessing a first 2d image depicting a patient's face and teeth; determining edges of one or more oral features in the first 2d image; obtaining an arch model including teeth with generic parameters; determining one or more case-specific parameters for a shape of at least one of the patient's teeth by fitting the teeth of the arch model to the edges of the one or more oral features in the first 2d image; generating a 3d parametric model of the patient's teeth by adjusting at least one of the teeth of the arch model based on the one or more case-specific parameters; and outputting the 3d parametric model or a second 2d image based on the 3d parametric model for display to a user on a display device.
