Abstract

The present invention provides a plastic tray orthodontic device ( 11 ) which may have embedded activators ( 10 ) and which is provided with an over-shell ( 12 ). The over-shell ( 12 ) acts as a force module.

Claims (33)

1. A system for correcting malocclusions to an end arch form comprising at least one activator embedded in a polymeric or elastic inner shell and a polymeric or elastic over-shell wherein said over-shell includes a hollow portion and is at least partially in the desired end arch form such that said over-shell acts as a force module and wherein a retaining device is formed into the over-shell to hold the inner shell and over-shell together while allowing separation of the shells without damaging the shells.

2. The system of claim 1 , wherein the system is free of arch wires.

3. The system of claim 1 , wherein the system is free of metal.

4. A system for correcting malocclusions to an end arch form comprising at least one activator embedded in a polymeric or elastic inner shell and a polymeric or elastic over-shell wherein said over-shell includes a hollow portion and is at least partially in the desired end arch form such that said over-shell acts as a force module and wherein a retaining device is provided having locking and removal bends placed in the over-shell for holding the inner shell and over shell together while allowing separation of the shells without damaging the shells.

5. A system for correcting malocclusions to an end arch form comprising at least one activator embedded in a polymeric or elastic inner shell and a polymeric or elastic over-shell and a database,

(i) wherein said over-shell includes a hollow portion and is at least partially in the desired end arch form such that said over-shell acts as a force module,

(ii). wherein activator values are digitally stored in the database to simulate the effect on the teeth in order to select the desired said activator;

(iii). wherein the over-shell varies in thickness such that an anterior over-shell portion has a smaller thickness relative to a thickness of a posterior over-shell portion; and

(iv). wherein a retaining device is formed into the over-shell to hold the inner shell and over-shell together while allowing separation of the shells without damaging the shells.

6. The system of claim 5 wherein the at least one activator is made from a translucent or transparent material that is color stable and follows a proven orthodontic system of programmed activations.

7. The system of claim 5 , wherein the at least one activator is embedded in a polymeric inner shell with a synthetic elastic over-shell attached over the polymeric inner shell imparting force to the at least one activator for correcting the malocclusion.

8. The system of claim 5 , wherein the inner shell is thinner and spring-like while the outer over-shell issues a force consistent for orthodontic needs.

9. The system of claim 5 , wherein the at least one activator is selected from a plurality of activators in a prefabricated system of the database, the plurality of activators having a series of related values so that the at least one activator chosen is identified through simulation on a digital model of the malocclusion or to the doctor's prescription (Rx).

10. The system of claim 5 , wherein the at least one activator is formed of calcium phosphate or color stable plastics including polyacetyl.

11. A system for correcting malocclusions to an end arch form comprising at least one activator embedded in a polymeric or elastic inner shell and a polymeric or elastic over-shell and a database,

(i) wherein said over-shell includes a hollow portion and is at least partially in the desired end arch form such that said over-shell acts as a force module,

(ii) wherein activator values are digitally stored in the database to simulate the effect on the teeth in order to select the desired said activator;

(iii). wherein the at least one activators is made from a translucent or transparent material that is color stable and follows a proven orthodontic system of programmed activations;

(iv). wherein a retaining device is formed into the over-shell to hold the inner shell and over-shell together while allowing separation of the shells without damaging the shells; and

(v). wherein the system is free of arch wires.

12. The system of claim 11 , wherein the over-shell varies in thickness such that an anterior over-shell portion has a smaller thickness relative to a thickness of a posterior over-shell portion.

13. The system of claim 11 , wherein a thickness of the over-shell is varied over treatment so that in earlier treatment the posterior portion is thicker than the anterior portion.

14. A system for correcting malocclusions to an end arch form comprising at least one activator embedded in a polymeric or elastic inner shell and a polymeric or elastic over-shell and a database,

(i) wherein said over-shell includes a hollow portion and is at least partially in the desired end arch form such that said over-shell acts as a force module,

(ii) wherein activator values are digitally stored in the database to simulate the effect on the teeth in order to select the desired said activator,

(iii). wherein the at least one activator is selected from a plurality of activators in a prefabricated system of the database, the plurality of activators having a series of related values so that the at least one activator chosen is identified through simulation on a digital model of the malocclusion or to the doctor's prescription (Rx);

(iv). wherein the inner shell is thinner and spring-like while the outer over-shell issues a force consistent for orthodontic needs; and

(v). wherein a retaining device is provided having locking and removal bends placed in the over-shell for holding the inner shell and over shell together while allowing separation of the shells without damaging the shells.

15. The system of claim 14 , wherein:

(i).

(ii). the at least one activator is made from a translucent or transparent material that is color stable and follows a proven orthodontic system of programmed activation.

16. The system of claim 14 , wherein the over-shells and inner shells being able to be placed and removed by quadrant to increase or decrease the force as needed while providing easier placement by the patient.

17. The system of claim 14 , wherein a thickness of at least one of the over-shells is varied over treatment so that in earlier treatment the posterior portion is thicker than the anterior portion.
