METHOD AND SYSTEM FOR ACQUIRING THREE-DIMENSIONAL TEETH IMAGE

摘要

A method for obtaining a dental image, being a three-dimensional image of teeth, the method including: (a) providing a three-dimensional physical teeth model. The three-dimensional physical teeth model being either: a negative teeth model that includes a matrix with a plurality of cavities or recesses, each corresponding to a tooth; or a positive teeth model, that includes a matrix with a plurality of projections or bulges, each corresponding to a tooth; (b) removing portion of the model in a controlled, step-wise manner, and in each step acquiring an optical image of the model or of its removed portion, digitizing each of the optical images in order to obtain a plurality of digital images; and (c) compiling the plurality of digital images to obtain a three-dimensional digital dental image.
