Mandibular advancement and retraction via bone anchoring devices
Systems, methods, devices and apparatus for mandibular advancement or retraction via bone anchoring devices are described herein. In various aspects, an apparatus for treating a patient via mandibular advancement or retraction comprises a plurality of anchoring devices positioned in the patient's intraoral cavity. Each of the plurality of anchoring devices can be positioned in bone of the patient's upper jaw or bone of the patient's lower jaw. One or more connecting structures can be removably coupled to and extend between the plurality of anchoring devices in order to displace the lower jaw anteriorly or posteriorly relative to the upper jaw.
1. An apparatus for treating a patient via mandibular advancement or retraction, the apparatus comprising:
a plurality of anchoring devices configured to be positioned in bone of the patient's upper jaw or bone of the patient's lower jaw; and
one or more connecting structures removably couplable to and configured to extend between the plurality of anchoring devices to produce an anterior-posterior force component greater than a vertical force component along a vertical direction to displace the lower jaw anteriorly or posteriorly relative to the upper jaw.
2. The apparatus of claim 1 , wherein the vertical force component is zero.
3. The apparatus of claim 1 , wherein the one or more connecting structures are removably couplable to the plurality of anchoring devices by a mechanism.
4. The apparatus of claim 3 , wherein the mechanism is selected from one of a snap-fit coupling, magnetic coupling, interference fit, locking surface, adhesive, removable fastener, cam lock, interlocking mechanical coupling, or fastening feature.
5. The apparatus of claim 1 , wherein the one or more connecting structures comprise an elastic structure.
6. The apparatus of claim 5 , wherein the elastic structure is configured to exert anterior-posterior forces without applying vertical forces.
7. The apparatus of claim 1 , wherein the one or more connecting structures comprise a stiff structure.
8. The apparatus of claim 7 , wherein the stiff structure exhibits substantially no deformation under load.
9. The apparatus of claim 1 , wherein the connecting structure comprises a plate structure.
10. The apparatus of claim 9 , wherein the plate structure comprises a geometry selected from one of a circular, elliptical, triangular, and rectangular geometry.
11. A method for treating a patient via mandibular advancement or retraction, the method comprising:
positioning a plurality of anchoring devices in bone of the patient's upper jaw or bone of the patient's lower jaw; and
removably coupling one or more connecting structures to the plurality of anchoring devices, wherein the one or more connecting structures extends between the plurality of anchoring devices in order to produce an anterior-posterior force component greater than a vertical force component along a vertical direction to displace the lower jaw in an anterior-posterior direction relative to the upper jaw.
12. The method of claim 11 , wherein the vertical force component is zero.
13. The method of claim 11 , wherein the one or more connecting structures are removably couplable to the plurality of anchoring devices by a mechanism.
14. The method of claim 13 , wherein the mechanism is selected from one of a snap-fit coupling, magnetic coupling, interference fit, locking surface, adhesive, removable fastener, cam lock, interlocking mechanical coupling, or fastening feature.
15. The method of claim 11 , wherein the one or more connecting structures comprise an elastic structure.
16. The method of claim 15 , wherein the elastic structure is configured to exert anterior-posterior forces without applying vertical forces.
17. The method of claim 11 , wherein the one or more connecting structures comprise a stiff structure.
18. The method of claim 17 , wherein the stiff structure exhibits substantially no deformation under load.
19. The method of claim 11 , wherein the connecting structure comprises a plate structure.
20. The method of claim 19 , wherein the plate structure comprises a geometry selected from one of a circular, elliptical, triangular, and rectangular geometry.
