Abstract
The invention provides a method and system for obtaining a three-dimensional representation of a patient's teeth arrangement. A three-dimensional physical teeth model is provided, having a surface relief corresponding to the patient's teeth arrangement. Computerized tomography (CT) is applied to the three-dimensional physical teeth model, to thereby acquire data of multiple slices of at least a portion of the teeth model. The data is analyzed to produce a virtual three-dimensional representation of the teeth model or a portion thereof.
Claims12
A method for obtaining a three-dimensional representation of a patient's teeth arrangement, the method comprising:
- (a) providing a three-dimensional physical teeth model comprising an exterior model surface having a positive relief corresponding to said teeth arrangement;
- (b) applying an imaging process consisting of computerized tomography (CT) to said three-dimensional physical teeth model to thereby acquire data of multiple slices of at least a portion of said model, wherein the physical model is not destroyed in the imaging process;
- (c) analyzing said data, using CT as a primary acquired data source, to produce therefrom a plurality of sequential digital images of said at least a portion corresponding to said slices;
- and
- (d) producing said three-dimensional representation by integrating said plurality of sequential digital images to generate a virtual surface corresponding to said exterior model surface.
A method for obtaining a three-dimensional representation of a patient's teeth arrangement, the method comprising:
- (a) providing a three-dimensional physical teeth model comprising an exterior model surface having a positive relief corresponding to said teeth arrangement wherein said teeth model is a positive teeth model, comprising a matrix with a plurality of projections or bulges, each corresponding to a tooth;
- (b) applying an imaging process consisting of computerized tomography (CT) to said three-dimensional physical teeth model to thereby acquire data of multiple slices of at least a portion of said model, wherein the physical model is not destroyed in the imaging process;
- (c) analyzing said data, using CT as a primary acquired data source, to produce therefrom a plurality of sequential digital images of said at least a portion corresponding to said slices;
- and
- (d) producing said three-dimensional representation by integrating said plurality of sequential digital images to generate a virtual surface corresponding to said exterior model surface.
