Claims
- 1. A method for bite-setting computer models of teeth on a first jaw and a second jaw, comprising:
determining an initial position of the first jaw; and determining an optimal bite based on the initial position of the first jaw.
- 2. The method of claim 1, wherein the determining the initial position further comprises:
determining a corresponding tooth on the second jaw for every molar and premolar tooth in the first jaw; determining a transform for the first jaw; and applying the transform to the first jaw.
- 3. The method of claim 2, further comprising shifting the first jaw to be above the second jaw.
- 4. The method of claim 2, wherein determining the transform further comprises minimizing a sum of squared distances between corresponding teeth.
- 5. The method of claim 1, further comprising simulating physical force on the jaws.
- 6. The method of claim 1, further comprising applying gravity force (G force) to the jaw.
- 7. The method of claim 1, further comprising applying a repulsion force occurs between jaws if a collision occurs.
- 8. The method of claim 7, wherein the force is proportional to square of collision.
- 9. The method of claim 1, wherein the position of the first jaw is calculated from a model of solid body motion.
- 10. The method of claim 1, further comprising testing position stability when a final position of the first jaw is achieved.
- 11. The method of claim 10, further comprising applying force in a side direction to the jaw.
- 12. The method of claim 1, further comprising generating a new bite setting position if the final position is unstable.
- 13. The method of claim 1, further comprising determining a plurality of stable bite setting positions and selecting a bite setting position with minimal distance between corresponding teeth.
- 14. A system for bite-setting computer models of teeth on a first jaw and a second jaw, comprising:
means for determining an initial position of the first jaw; and means for determining an optimal bite based on the initial position of the first jaw.
- 15. A method for bite setting dental jaws, comprising:
digitally scanning PVS bites, upper arch and lower arch of a patient; displaying the upper arch, lower arch and the PVS bite on a computer screen; and comparing the digital bite against impressions on the PVS bite to determine proper bite-set.
