Abstract: A method and system for fabricating a dental appliance for orthodontic treatment. The method comprises the steps of obtaining three-dimensional dental data from a patient scan, locating initial tooth positions, generating optimal arch forms, and determining a digital model for fabricating an orthodontic aligner with additive device. The system comprises a scanning apparatus to acquire three-dimensional dental data, and a computer apparatus programmed with instructions for generating optimal arch forms, and determining a digital model for fabricating an orthodontic aligner with additive device.

Abstract: The present disclosure describes methods for improving semi-automatic and/or fully automatic tooth segmentation in reconstructed images of X-ray scans using multi-energy X-ray spectra and/or a multi-energy X-ray scanner at more than one energy. Such improved segmentation of teeth in a reconstructed image of an X-ray scan is a critical first step in the utilization of the image for applications in orthodontics, endodontics, and implant planning In accordance with the methods, tooth segmentation may be performed semi-automatically or automatically for images which are reconstructed from a multi-energy X-ray scan. The results of the tooth segmentation may be represented as an image map which identifies voxels which are within a tooth or as a three-dimensional (3D) grid or any other representation of a three-dimensional (3D) spatial region.

Abstract: A method for generating optimal arch forms for a patient's dental arch is presented. The method comprises: receiving first positional digital data for one or more teeth from a reconstructed 3D digital volume of the patient dental arch; (b) generating second positional digital data for the one or more teeth according to a desired dental arch form for the patient; (c) calculating a first displacement data for one or more teeth according to the first positional and second positional digital data; (d) detecting teeth collision values based on the first displacement data; (e) calculating a second displacement data for one or more teeth based on the detected teeth collision values; and (f) reporting a combination of the first displacement data and second displacement data for repositioning one tooth or more teeth of the dental arch.

Abstract: The present disclosure describes a system and methods for autonomous segmentation of volumetric dental images, such as those produced by an imaging system, The methods, implemented by the system, acquire a volume image of a patient and extract a volume of interest comprising patient dentition from the acquired volume image. A first plane is extended through maxillary portions of the patients jaw and a second plane through mandibular portions of the patients jaw. A maxillary sub-volume is generated from the volume of interest according to the first plane and a mandibular sub-volume from the volume of interest according to the second plane. Maximum intensity projection images are formed for each sub-volume and teeth are delineated from these images. Teeth are segmented within each sub-volume according to the tooth delineation for their respective sub-volume.
