Systems and methods for correcting malocclusions of teeth
A system for correcting class III malocclusions is disclosed. The system may include a maxilla appliance having tooth receiving cavities shaped to receive teeth of the maxilla and a first coupling for receiving an elastic. The system may also include a mandibular appliance having tooth receiving cavities shaped to receive teeth of the mandible. In some embodiments, the system includes a class III corrective appliance having a first mount shaped to engage with the mandibular arch of the patient and having a second coupling shaped to receive the elastic.
1. A system for correcting malocclusions of a patient comprising:
a maxillary appliance having tooth receiving cavities shaped to receive teeth of the maxilla and a first coupling disposed at a first distance away from an occlusal plane towards the gingival line of the patient, wherein the first coupling is configured for receiving an elastic;
a mandibular appliance having tooth receiving cavities shaped to receive teeth of the mandible; and
a corrective appliance having (i) a first mount shaped to engage with the mandibular appliance of the patient at a first location and having a second coupling shaped to receive the elastic, (ii) a second mount shaped to engage with the mandibular appliance of the patient at a second location, and (iii) an arm extending from the first mount to a position away from the occlusal surface of the first mount towards the gingival line, the second coupling located at a terminal end of the arm.
2. The system of claim 1 , wherein the first location and second location are of respective first and second canines of the patient.
3. The system of claim 1 , further comprising:
a bridge extending between and connecting the first mount and the second mount, the bridge having a surface shaped to match a lingual facing anterior surface of the patient's mandibular arch.
4. The system of claim 1 , wherein the second coupling is at the first distance away from the occlusal plane towards the gingival line of the patient.
5. The system of claim 1 , wherein the first mount is shaped to engage with the mandibular appliance of the patient at the central incisors.
6. The system of claim 1 , wherein:
the first coupling is located at the first distance away from the occlusal plane towards the gingival line of the patient and the second coupling is located a second distance above the occlusal plane of the patient, the first distance being equal to the second distance.
7. The system of claim 1 , wherein:
the first coupling is located the first distance away from the occlusal plane towards the gingival line of the patient and the second coupling is located a second distance away from the occlusal plane towards the gingival line of the patient, the first distance being greater than the second distance.
8. The system of claim 1 , further comprising:
a guard attached to the second coupling and shaped to displace the lips or the cheeks of the patient away from the teeth of the patient.
9. The system of claim 1 , further comprising:
a first maxillary device extending from a buccal surface of the maxillary appliance and having a first engagement surface; and
a second mandibular device extending from a buccal surface of the mandibular appliance and having an engagement surface, wherein the engagement of the first engagement surface with the second engagement surface advances the maxilla of the patient in an anterior direction.
10. The system of claim 9 , wherein the maxillary appliance is a transpalatal appliance and includes a transpalatal extension that extends between the tooth receiving cavities of a left side of the maxillary appliance and the tooth receiving cavities of a right side of the maxillary appliance.
11. The system of claim 1 , wherein:
the tooth receiving cavities of the maxillary appliance are shaped to reposition at least one tooth of the maxillary arch; and
the tooth receiving cavities of the mandibular appliance are shaped to reposition at least one tooth of the mandibular arch.
12. The system of claim 1 , wherein:
the corrective appliance is shaped to releasable couple to the mandibular appliance.
13. The system of claim 1 , further comprising:
a first appliance coupling at an external surface of the mandibular appliance; and
a second appliance coupling at a tooth facing surface of the corrective appliance, the first appliance coupling and the second appliance coupling shaped to match each other and releasably couple the mandibular appliance to the corrective appliance.
14. A system for correcting malocclusions of a patient comprising:
a maxillary appliance having tooth receiving cavities shaped to receive and reposition the teeth of the maxilla and a first coupling for receiving an elastic;
a corrective appliance having tooth receiving cavities shaped to receive teeth of the mandible and a second coupling shaped to receive the elastic, and
an arm extending from the corrective appliance to a position away from the occlusal surface of the corrective appliance towards the gingival line, the second coupling located at a terminal end of the arm.
15. The system of claim 14 , wherein the second coupling extends from a buccal surface of corrective appliance at the location of the central incisors.
16. The system of claim 14 , wherein:
the first coupling is located the first distance away from the occlusal plane towards the gingival line of the patient and the second coupling is located a second distance away from the occlusal plane towards the gingival line of the patient, the first distance being equal to the second distance.
17. The system of claim 14 , wherein:
the first coupling is located a first distance away from the occlusal plane towards the gingival line of the patient and the second coupling is located a second distance away from the occlusal plane towards the gingival line of the patient, the first distance being greater than the second distance.
18. The system of claim 14 , wherein:
the tooth receiving cavities of the maxillary appliance are shaped to reposition at least one tooth of the maxillary arch; and
the tooth receiving cavities of the corrective appliance are shaped to reposition at least one tooth of the mandibular arch.
19. The system of claim 14 , further comprising:
a guard attached to the second coupling and shaped to displace the lips or the cheeks of the patient away from the teeth of the patient.
20. The system of claim 14 , further comprising:
a first maxillary device extending from a buccal surface of the maxillary appliance and having a first surface; and
a second maxillary device extending from a buccal surface of the corrective appliance and having an engagement surface, wherein the engagement of the first engagement surface with the second engagement surface advances the maxilla of the patient in an anterior direction.
