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 positioned in the patient's intraoral cavity, wherein each of the plurality of anchoring devices is positioned in bone of the patient's upper jaw or bone of the patient's lower jaw; and
one or more connecting structures removably coupled to and extending between the plurality of anchoring devices in order to displace the lower jaw anteriorly or posteriorly relative to the upper jaw,
wherein the one or more connecting structures and the plurality of anchoring devices are arranged to constrain vertical displacement of the lower jaw relative to the upper jaw in order to inhibit contact between teeth of the lower jaw and teeth of the upper jaw wherein the one or more connecting structures are arranged to produce an anterior-posterior force component that displaces the lower jaw anteriorly or posteriorly relative to the upper jaw.
2. The apparatus of claim 1 , wherein the one or more connecting structures, when coupled to the plurality of anchoring devices, are capable of producing the anterior-posterior force component without producing a vertical force component.
3. The apparatus of claim 1 , wherein the one or more connecting structures comprise at least one elastic structure.
4. The apparatus of claim 1 , wherein the one or more connecting structures are arranged to apply a moment to at least one of the upper jaw or the lower jaw.
5. The apparatus of claim 4 , wherein the one or more connecting structures comprise a connecting structure configured to support one or more of a bending load or a shear load in order to apply the moment.
6. The apparatus of claim 5 , wherein the connecting structure is coupled to the upper jaw or the lower jaw via at least one of the plurality of anchoring devices that constrains rotation of the connecting structure along at least one direction of rotation in order to apply the moment at a location near the at least one of the plurality of anchoring devices.
7. The apparatus of claim 1 , wherein the plurality of anchoring devices comprises three or more anchoring devices.
8. A method for treating a patient via mandibular advancement or retraction, the method comprising:
positioning a plurality of anchoring devices in the patient's intraoral cavity, wherein each of the plurality of anchoring devices is positioned 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 extend between the plurality of anchoring devices in order to displace the lower jaw anteriorly or posteriorly relative to the upper jaw,
wherein the one or more connecting structures and the plurality of anchoring devices are arranged to constrain vertical displacement of the lower jaw relative to the upper jaw in order to inhibit contact between teeth of the lower jaw and teeth of the upper jaw wherein the one or more connecting structures are arranged to produce an anterior-posterior force component that displaces the lower jaw anteriorly or posteriorly relative to the upper jaw.
9. The method of claim 8 , wherein the one or more connecting structures, when coupled to the plurality of anchoring devices, are capable of producing the anterior-posterior force component without producing a vertical force component.
10. The method of claim 8 , wherein the one or more connecting structures comprise at least one elastic structure.
11. The method of claim 8 , wherein the one or more connecting structures are arranged to apply a moment to at least one of the upper jaw or the lower jaw.
12. The method of claim 11 , wherein the one or more connecting structures comprise a connecting structure configured to support one or more of a bending load or a shear load in order to apply the moment.
13. The method of claim 12 , wherein the connecting structure is coupled to the upper jaw or the lower jaw via at least one of the plurality of anchoring devices that constrains rotation of the connecting structure along at least one direction of rotation in order to apply the moment at a location near the at least one of the plurality of anchoring devices.
14. The method of claim 8 , wherein the plurality of anchoring devices comprises three or more anchoring devices.
