Systems and methods for temporally staging teeth
Systems and methods are disclosed for moving teeth by moving a first tooth; and moving a second tooth while isolating the first tooth at a rest position.
1. A method for moving teeth, comprising:
moving at least one first tooth with a dental appliance having a number of cavities in which one or more teeth are positioned and wherein the at least one first tooth is positioned in one of the cavities; and
moving at least one second tooth while isolating the at least one first tooth by relieving the at least one first tooth of any applied force from the appliance or the second tooth, wherein relieving the force applied to the at least one first tooth is accomplished by creating space around the tooth and within the one of the cavities of the appliance, such that no force applying contact is made by the appliance or the second tooth.
2. The method of claim 1 , wherein the at least one second tooth is moved for a first duration and immobilized for a second duration.
3. The method of claim 2 , wherein the first duration is on an hourly basis, a daily basis, or a weekly basis.
4. The method of claim 1 , comprising generating a plurality of appliances based on the moving of the at least one first tooth and the at least one second tooth, wherein the appliances comprise polymeric shells having cavities and wherein the cavities of successive shells have different geometries shaped to receive and resiliently reposition the at least one first and second teeth from one arrangement to a successive arrangement.
5. The method of claim 4 , wherein a first cavity isolates the at least one first tooth at the rest position.
6. The method of claim 4 , wherein a second cavity urges the at least one second tooth to the successive arrangement.
7. The method of claim 4 , further comprising replacing an appliance on an intra-day basis.
8. The method of claim 4 , further comprising replacing an appliance on a daily basis.
9. The method of claim 4 , further comprising replacing an appliance on a multi-day basis.
10. The method of claim 4 , further comprising replacing an appliance on an intra-week basis.
11. The method of claim 4 , further comprising replacing an appliance on a weekly basis.
12. The method of claim 1 , wherein the at least one first tooth is a group of contiguous teeth.
13. the method of claim 1 , wherein the at least one first tooth is a group of noncontiguous teeth.
14. The method of claim 1 , wherein the at least one second tooth is a group of contiguous teeth.
15. The method of claim 1 , wherein the at least one second tooth includes a group of noncontiguous teeth.
