Dynamic dental arch map

Abstract

Method for automatically assigning numeric labels to teeth in a dental arch map provides a segmented 3D surface image of patient dentition having identified individual teeth and determined tooth position in the dental arch. A tooth contour for the identified teeth is defined. The tooth type is identified as one of incisor, canine, premolar, or molar. A display of the tooth contour is labeled withan assigned tooth number according to the tooth position, tooth contour, and tooth type. The labeled mapping is displayed.

Description

technical field [0001] The present disclosure relates generally to imaging methods and devices, and more particularly to methods and devices for generating a two-dimensional map of a dental arch from three-dimensional surface information about a patient. Background technique [0002] Conventional dental charts or arch diagrams are used to assist physicians and larger dental teams, providing a vehicle for organizing notes and other information related to each particular patient's dental condition and treatment. In routine practice, the same basic dental chart is used as a starting point for each patient. Using this mapping of the dental arch as a reference, diagnostic assessments and treatment procedures can be made and can be associated with each tooth as needed. Dental charts are complex, intricate and contain vast amounts of data for each patient. See, eg, US Patent No. 8,416,984 entitled "Automatic tooth charting using digital images." [0003] However, routinely used ...

AI Technical Summary

Problems solved by technology

[0003] However, routinely used arch maps are standard cartographic arrangements and may not apply equally well to every patient

There are a number of conditions that have the potential to render standard arch drawings incorrect or confusing for individual patients and may tend to complicate the use of standard drawings of tooth structure
