Abstract
System for scanning a subject's teeth. Described herein are intraoral scanning apparatuses for generating a three-dimensional model of a subject's intraoral region (e.g., teeth). These apparatuses may be used for identifying and evaluating lesions, caries and cracks in the teeth.
Claims24
An intraoral scanning system for scanning a patient's dentition, the system comprising:
- a wand having at least one image sensor, a visible light light source and near-infrared (near-IR) light light source;
- one or more processors operably connected to the wand, the one or more processors configured to:
- receive scan data of a patient's dentition comprising a first set of two-dimensional (2D) images taken with an intraoral scanner capturing surface topology using structured light;
- receive a plurality of 2D near-infrared (near-IR) images of the patient's dentition taken with the intraoral scanner while taking the first set of 2D images;
- display a three-dimensional (3D) model of at least a portion of the patient's dental arch based on the captured surface topology;
- and
- display one or more 2D near-IR images from the plurality of 2D near-IR images correlating to the displayed 3D model of at least the portion of the patient's dental arch.
4 more elements
An intraoral scanning system, comprising:
- a wand configured to detect visible light and near-infrared (near-IR) light;
- a display subsystem;
- and
- one or more processors operably connected to the wand and display subsystem, the one or more processors configured to control:
- scanning a patient's dentition with visible light to capture surface topology of the patient's dentition using structured light;
- imaging the patient's dentition with near-infrared (near-IR) light to capture a plurality of two-dimensional (2D) near-IR images of the patient's dentition during the scanning of the patient's dentition with visible light;
- displaying a three-dimensional (3D) model of at least a portion of the patient's dental arch based on the captured surface topology;
- and
- displaying one or more 2D near-IR images from the plurality of 2D near-IR images correlating to the displayed 3D model of at least the portion of the patient's dental arch.

- scanning a patient's dentition with visible light to capture surface topology of the patient's dentition;
- imaging the patient's dentition with near-infrared (near-IR) light to capture a plurality of two-dimensional (2D) near-IR images of the patient's dentition during the scanning of the patient's dentition with visible light;
- displaying a three-dimensional (3D) model of at least a portion of the patient's dental arch based on the captured surface topology;
- and
- displaying one or more 2D near-IR images from the plurality of 2D near-IR images correlating to the displayed 3D model of at least the portion of the patient's dental arch.
