  • Publication number: 20220012888
    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.

  • Publication number: 20210343020
    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.

  • Publication number: 20210153976
    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.

  • Patent number: 11017535
    Abstract: 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.

  • Publication number: 20200015936
    Abstract: A method for generating a digital model of dentition, executed at least in part by a computer, acquires a 3-D digital mesh that is representative of the dentition along a dental arch, including includes braces, teeth, and gingival tissue. The method modifies the 3-D digital mesh to generate a digital mesh dentition model by processing the digital mesh and automatically detecting one or more initial bracket positions from the acquired mesh, processing the initial bracket positions to identify bracket areas for braces that lie against tooth surfaces, identifying one or more brace wires extending between brackets, removing one or more brackets and one or more wires from the dentition model, and forming a reconstructed tooth surface within the digital mesh dentition model where the one or more brackets have been removed. The modified 3-D digital mesh dentition model is displayed, stored, or transmitted over a network to another computer.
