US 2026/0268495 A1 · IMAGE-BASED TOOTH SEGMENTATION AND IDENTIFICATION

Abstract

Systems and methods for identifying teeth in a patient image are provided. A system can include processor(s) and a memory operably coupled to the processor(s) and storing instructions that, when executed by the processor(s), cause the system to perform operations including accessing a 2D image including a depiction of a patient's teeth, applying a segmentation algorithm to the 2D image, and generating tooth assignments. The segmentation algorithm may be configured to identify a plurality of regions in the 2D image, each region corresponding to an estimated location of a tooth of the patient's teeth in the 2D image, and determine a tooth mask and a tooth identifier for each tooth, where the determination for each tooth is based on features of the region corresponding to the estimated location of the tooth and features of the regions corresponding to estimated locations of one or more teeth proximate to the tooth.

Dependent claims

A system for identifying teeth in a patient image, the system comprising:

one or more processors;
and
a memory operably coupled to the one or more processors and storing instructions that, when executed by the one or more processors, cause the system to perform operations comprising:
accessing a two-dimensional (2D) image comprising a depiction of a patient's teeth;
applying a segmentation algorithm to the 2D image, wherein the segmentation algorithm is configured to:
identify a plurality of regions in the 2D image, each region corresponding to an estimated location of a tooth of the patient's teeth in the 2D image, and
determine a tooth mask and a tooth identifier for each tooth of the patient's teeth in the 2D image, wherein the determination for each tooth is based on features of the region corresponding to the estimated location of the tooth and features of the regions corresponding to estimated locations of one or more teeth proximate to the tooth;
and
generating tooth assignments by assigning each tooth of the patient's teeth in the 2D image to the respective determined tooth mask and the respective determined tooth identifier.

6 more elements

A computer-implemented method for identifying teeth in a patient image, the computer-implemented method comprising, by one or more processors:

accessing a two-dimensional (2D) image comprising a depiction of a patient's teeth;
transmitting, to a server computing device, the 2D image;
and
receiving, from the server computing device, a tooth assignment for each tooth of the patient's teeth in the 2D image, wherein the tooth assignments are generated by:
applying a segmentation algorithm to the 2D image, wherein the segmentation algorithm is configured to:
identify a plurality of regions in the 2D image, each region corresponding to an estimated location of a tooth of the patient's teeth in the 2D image, and
determine a tooth mask and a tooth identifier for each tooth of the patient's teeth in the 2D image, wherein the determination for each tooth is based on features of the region corresponding to the estimated location of the tooth and features of the regions corresponding to estimated locations of one or more teeth proximate to the tooth;
and
generating tooth assignments by assigning each tooth of the patient's teeth in the 2D image to the respective determined tooth mask and the respective determined tooth identifier.
