Abstract

A method and apparatus are provided for changing the form of the jaw and facial bones of an adult patient that did not develop fully during childhood. The method utilizes a device having a plate body with an expansion screw device that fits within the mouth of the patient, flap springs that project from the plate body and an overlay extending from the plate body. The device is placed within the mouth of the patient so that the overlay is in a position between at least two opposing teeth. In this position the flap springs press against selected teeth that are out of alignment in order to urge those teeth back into place. This force on the teeth causes the jawbone to expand to accept the teeth in their proper position(s). Also, the device is arranged such that the opposing teeth contact the overlay during swallowing, which causes the patient'"'"'s facial muscles to intermittently pull on the facial bones. This intermittent application of force to the facial bones causes these bones to further develop toward a symmetrical appearance of the face and the positioning of out of place teeth/tooth into proper position. The device can be adjusted by small motors under the control of a microprocessor located on the body plate based on readings from sensors on the flap springs.

Claims

1. A method for changing the form of at least one of the facial and jaw bones of a patient in which such bone did not develop fully during childhood, said method comprising the steps of:

providing a device having a plate body that fits within the mouth of the patient, flap springs that project from the plate body and an overlay extending from the plate body;

placing the device within the mouth of the patient so that the overlay is in a position between at least an upper and lower tooth of the patient, the flap springs press against at least one selected tooth that is out of place and the plate body is spaced from the patient'"'"'s tissue, including the palate; and

arranging the shape and placement of the device such that contact of the patient'"'"'s upper tooth and lower tooth or teeth with the overlay causes the patient'"'"'s facial muscles to intermittently pull on at least one of the bones essentially each time the patient swallows, thereby causing further development of the at least one bones toward a symmetrical appearance of the face and the positioning of the out of place tooth or teeth into a proper position or positions.

2. The method according to claim 1, further comprising the step of placing said overlay only between teeth on one side of the patient'"'"'s mouth.

3. The method according to claim 2, wherein said overlay is placed on a side of said patient'"'"'s mouth corresponding to the side where at least one of the bones did not fully develop during childhood.

4. The method according to claim 1, further comprising the step of placing said overlay between teeth on both sides of the patient'"'"'s mouth.

5. The method according to claim 1, wherein said flap springs cause the jawbone of the patient to expand to accommodate an out of place tooth or teeth.

6. The method according to claim 5, wherein the plate body is in two pieces connected by a motorized screw to bring the halves together or moving them apart, and further comprising the step of operating the screw motor periodically to adjust the spacing between the plate body halves to compensate for expansion of the jawbone.

7. The method according to claim 6, wherein the device further includes sensors to detect the pressure applied to the tooth, and further comprising the step of determining the pressure on the tooth by reading the sensors and the step of operating the screw motor based on the pressure readings.

8. The method according to claim 7, wherein the device further includes a processor that reads the sensor and controls the screw motor, and wherein the step of operating the screw motor is carried out by the processor based on the sensor readings and predetermined parameters.

9. The method according to claim 5, wherein the plate body is in two pieces connected by a motorized screw for bring the halves together or moving them apart, wherein the device further includes sensors for sensing the pressure applied to the tooth, a micro-motor located between the plate body and the flap spring for controlling the pressure applied by the flap spring, and a processor that reads the sensor and controls the screw motor and the micro-motor, and further comprising the steps of:

determining the pressure on the tooth by the processor reading the sensors;

and causing the processor to operate at least one of the screw motor and micro-motor periodically to adjust the spacing between the plate body halves to compensate for expansion of the jawbone and to adjust the pressure on the tooth by the flap spring.

10. The method according to claim 1, wherein the device further includes a micro-motor located between the plate body and the flap spring for controlling the pressure applied by the flap spring, and further comprising the step of operating the micro-motor periodically to adjust the pressure on the tooth by the flap spring.

11. The method according to claim 10, wherein the device further includes sensors to detect the pressure applied to the tooth, and further comprising the step of determining the pressure on the tooth by reading the sensors and the step of operating the micro-motor based on the pressure readings.

12. A device comprising:

a plate body in the form of two halves and designed to fit within the mouth of a patient;

an overlay extending from at least one of the plate body halves, said overlay being designed to fit between at least an upper tooth and an opposing lower tooth of the patient so the patient'"'"'s mouth cannot fully close;

a clasp connected to said plate body, said clasp selectively connecting said device to at least one tooth of a patient;

a motorized screw connection between the halves of the plate body to move the halves toward or away from each other;

at least one flap spring connected to said plate body and designed to contact and apply pressure to at least one tooth of the patient; and

at least one sensor located on the flap spring and measuring the pressure applied to the tooth by the flap spring.

13. The device according to claim 12, wherein said plate body is spaced from the patient'"'"'s tissue, including the palate.

14. The device according to claim 12 further comprising a pressure control device that varies the pressure applied to the tooth by the flap spring.

15. The device according to claim 12, wherein said flap spring is T-shaped including a tag portion connected to the plate body and a tooth supporting portion contacting at least one tooth, said tooth supporting portion extending for a distance equal to at least the width of two teeth.

16. The device according to claim 12, wherein said plate body is made of plastic, including but not restricted to fabrication by reverse engineering.

17. The device according to claim 16, wherein said plastic is acrylic.

18. The device according to claim 12, wherein said overlay, at least in the area where it contacts said tooth, has a thickness ranging from approximately 0.5 mm to approximately 15.0 mm.

19. The device according to claim 18, wherein said overlay, at least in the area where it contacts said tooth, has a thickness ranging from approximately 1.0 mm to approximately 6.0 mm.

20. The device according to claim 19, wherein said overlay, at least in the area where it contacts said tooth, has a thickness ranging from approximately 2.0 mm to approximately 4.0 mm.

21. The device according to claim 12, wherein said overlay is disposed solely on one side of said plate body.

22. The device according to claim 12, further comprising a second overlay, wherein said overlay is disposed on both sides of said plate body.

23. The device according to claim 12, wherein said clasp includes an archway extending around at least one of said posterior teeth.
