AI Technical Summary

Technical Problem

Conventional intraoral imaging techniques struggle to accurately characterize material composition, provide detailed information on tooth structure, and combine scans effectively, leading to challenges in identifying materials like amalgams, detecting early caries, periodontal pocketing, gingival lesions, and cracks within the depth profile without adding components to existing imaging apparatus.

Method used

A method using optical coherence tomography (OCT) to acquire multiple scans, reconstruct a 3D surface, associate material composition with 3D coordinates, label identified materials, and display or store the labeled image content, employing a trained classifier to enhance material identification.

Benefits of technology

Enables accurate identification of intraoral materials, automates dental chart generation, detects demineralization, periodontal pocketing, and other conditions, improving diagnostic capabilities without additional accessories.

Abstract

A method for imaging an intraoral sample using optical coherence tomography (OCT) or ultrasound to acquire image data content from multiple scans of the sample using a hand-held, depth-penetrating scanner and reconstruct a 3D surface according to the acquired measurements. For coordinate locations on the reconstructed 3D surface, the method repeats a sequence of identifying scan data related to material at the coordinate location; computing material content according to a consensus of the identified scan data; and labeling the coordinate location according to the computed consensus for the material content. The method records the label assignments and displays, stores, or transmits the labeled, reconstructed image content.
