System and method for digital tooth imaging
Method and system for managing multiple impressions of a patient's jaw for an orthodontic treatment is provided. The method includes scanning at least a first impression and a second impression of same jaw for the orthodontic treatment; determining if the first jaw impression and the second jaw impression have distortion in different areas; selecting the first jaw impression or the second jaw impression as a base impression; and replacing a distorted tooth data from the base impression with data for the same tooth from a non-base impression. The method also includes scanning at least a first jaw impression for the orthodontic treatment; scanning a bite impression for the orthodontic treatment; matching the scanned first jaw impression with the scanned bite impression; comparing bite information with a tooth occlusal surface; and determining if reconstruction is to be performed on the tooth occlusal surface.
1. A method for managing multiple impressions of a patient's jaw for an orthodontic treatment, comprising:
scanning a first impression and a second impression of the patient's jaw to create a first digital image of the first impression and a second digital image of the second impression;
digitally processing the first digital image into a first plurality of digital objects, each representing a single tooth in the jaw, and digitally processing the second digital image into a second plurality of digital objects, each of the second plurality of digital objects corresponding to one of the first plurality of digital objects;
storing each of the first and second pluralities of digital objects obtained by digitally processing the first and second digital images;
determining if the first jaw impression and the second jaw impression have distortion in non-corresponding ones of the first and second pluralities of digital objects;
if the first and second jaw impressions have distortion in non-corresponding ones of the first and second pluralities of digital objects, selecting a base impression and a non-base impression from the first jaw impression and the second jaw impression; and
correcting a distorted digital object from the base impression using a corresponding digital object from the non-base impression.
2. The method of claim 1 , wherein the steps of digitally processing the first and second digital images include digitally segmenting the first digital image and the second digital image respectively into the first and second pluralities of digital objects.
3. The method of claim 1 , wherein the steps of digitally processing the first and second digital images include surface matching the first and second digital images to provide the first and second pluralities of digital objects.
4. The method of claim 1 , wherein the step of determining if the first jaw impression and the second jaw impression have distortion in non-corresponding ones of the first and second pluralities of digital objects includes aligning the first and second digital images.
5. The method of claim 1 , wherein the step of correcting a distorted digital object from the base impression includes replacing the distorted digital object with a corresponding digital object from the non-base impression.
6. The method of claim 1 , wherein the step of correcting a distorted digital object from the base impression includes using a corresponding digital object from the non-base impression as a template for the distorted digital object.
7. The method of claim 4 , wherein the aligning of the first and second digital images includes matching undistorted corresponding digital objects in the first and second pluralities of digital objects, and by excluding distorted digital objects in the first and second pluralities of digital objects.
8. A system for managing multiple digital impressions of a patient's jaw for orthodontic treatment, comprising:
a scanning apparatus configured for scanning a first impression and a second impression of the patient's jaw to create a first digital image of the first impression and a second digital image of the second impression;
a processing module configured for (a) digitally processing the first digital image into a first plurality of digital objects, each representing a single tooth in the jaw, and digitally processing the second digital image into a second plurality of digital objects, each of the second plurality of digital objects corresponding to one of the first plurality of digital objects, (b) determining if the first jaw impression and the second jaw impression have distortion in non-corresponding ones of the first and second pluralities of digital objects, (c) permitting the selection of a base impression and a non-base impression from the first jaw impression and the second jaw impression if the first and second jaw impressions have distortion in non-corresponding ones of the first and second pluralities of digital objects; and (d) correcting a distorted digital object from the base impression using a corresponding digital object from the non-base impression.
9. The system of claim 8 , wherein the processor is configured for digitally processing the first and second digital images by digitally segmenting the first digital image and the second digital image respectively into the first and second pluralities of digital objects.
10. The system of claim 8 , wherein the processor is configured for digitally processing the first and second digital images by surface matching the first and second digital images to provide the first and second pluralities of digital objects.
11. The system of claim 8 , wherein the processor is configured for determining if the first jaw impression and the second jaw impression have distortion in non-corresponding ones of the first and second pluralities of digital objects by aligning the first and second digital images.
12. The system of claim 8 , wherein the processor is configured for correcting a distorted digital object from the base impression by replacing the distorted digital object with a corresponding digital object from the non-base impression.
13. The system of claim 8 , wherein the processor is configured for correcting a distorted digital object from the base impression by using a corresponding digital object from the non-base impression as a template for the distorted digital object.
14. The system of claim 11 , wherein the processor is configured for aligning the first and second digital images by matching undistorted corresponding digital objects in the first and second pluralities of digital objects, and by excluding distorted digital objects in the first and second pluralities of digital objects.
