Abstract

Methods and systems for treating teeth include capturing a digital dental model taken within an oral cavity; modifying the digital model in planning a dental treatment or in designing a tooth die model for a dental prosthetic; creating physical models from the original or modified digital models: and using the physical models as a pattern for fabrication and fit check of a dental prosthetic.

Claims (17)

1. A method for treating teeth, comprising:

intra-orally scanning a dental structure to generate a digital dental model, said digital dental model comprising a three dimensional representation of teeth and gingiva surface contours in the scanned dental structure;

modifying the digital dental model to isolate a tooth and create one or more digital isolated tooth die models, wherein said digital isolated tooth die models comprise a digital three dimensional tooth surface, a tooth base and a mounting post or stem dimensioned to the tooth base;

creating physical models from the digital dental model and said one or more digital isolated tooth die models using Stereo Lithographic Apparatus (SLA) equipment, where said physical models replicate the structures of the digital dental model and said one or more digital isolated tooth die models; and

using the physical models as a pattern for fabrication and fit check of a dental prosthetic.

2. The method of claim 1 , further comprising utilizing a dental computer aided design system to view the digital dental model and create the one or more digital isolated tooth die models.

3. The method of claim 2 , wherein creating the one or more digital isolated tooth die models includes selecting a tooth to be isolated, isolating said tooth and adding a stem or pin to a base of the isolated tooth, and saving the digital isolated tooth die model as a unique digital file.

4. The method of claim 1 , wherein the physical models contain unique identifier markings.

5. A system for treating teeth, comprising:

means for intra-orally scanning a dental structure to generate a digital dental model, said digital dental model comprising a three dimensional representation of teeth and gingiva surface contours in the scanned dental structure;

means for modifying the digital dental model to isolate a tooth and create one or more digital isolated tooth die models, wherein said digital isolated tooth die models comprise a digital three dimensional tooth surface, a tooth base and a mounting post or stem dimensioned to the tooth base; and

means for creating physical models of the digital dental model and said one or more digital isolated tooth die models, whereby the physical models can serve as a pattern for fabrication and fit check of a dental prosthetic.

6. A system for treating teeth, comprising:

an intra-oral scanner to generate a digital dental model, said digital dental model comprising a three dimensional representation of teeth and gingiva surface contours in a scanned dental structure;

a dental computer aided design system for modifying the digital dental model in designing one or more digital isolated tooth die models, wherein said digital isolated tooth die models comprise a digital three dimensional tooth surface, a tooth base and a mounting post or stem dimensioned to the tooth base; and

a Stereo Lithographic Apparatus (SLA) system coupled to the dental computer aided design system for creating physical models from the digital dental model and said one or more digital isolated tooth die models, whereby the physical models can serve as a pattern for fabrication and fit check of a dental prosthetic.

7. The system of claim 6 , wherein the dental computer aided design system is used to add an identifier marking that is evident on the physical models.
