Abstract
The present invention provides protective repositioning appliances, accommodating mouth guards, and covering guards that protect an orthodontic patient against impact-induced injuries, as well as related systems and methods. A protective appliance can include teeth receiving cavities shaped to receive and reposition a patient's teeth and can include an occlusal portion having an impact-absorbing compliance. An accommodating mouth guard can include teeth receiving cavities shaped to accommodate a patient's teeth from a first arrangement to a second arrangement and can include an occlusal portion having an impact-absorbing compliance. A covering guard can include a guard segment that covers at least a portion of an appliance. The combination of a guard segment and an appliance can provide an occlusal compliance that absorbs impacts.
Claims20
A system that provides protection against impact-induced injuries during an orthodontic treatment, the system comprising:
- an aligner configured to reposition a first plurality of a patient's teeth on a first jaw of the patient during a stage of the orthodontic treatment from a first arrangement toward a second arrangement different from the first arrangement;
- a first mouth guard configured to protect the first plurality of the patient's teeth on the first jaw of the patient during the orthodontic treatment without applying repositioning forces to the first plurality of the patient's teeth, the first mouth guard comprising:
- a first plurality of cavities configured to receive the first plurality of the patient's teeth on the first jaw of the patient during the stage of the orthodontic treatment, wherein the first plurality of cavities comprise an accommodation envelope providing a swept volume that accommodates the aligner when worn on the first plurality of the patient's teeth, and wherein the swept volume accommodates at least one tooth of the first plurality of the patient's teeth along a spatial path from a first location of the at least one tooth in the first arrangement to a second location of the at least one tooth in the second arrangement;
- and
- a first occlusal portion having a first side and a second side opposite the first side, wherein the first side is adjacent to the first plurality of cavities comprising the accommodation envelope providing the swept volume, and the second side includes a first plurality of interfacing surfaces;
- and
- a second mouth guard configured to protect a second plurality of the patient's teeth on a second jaw of the patient during the orthodontic treatment, the second mouth guard comprising:
- a second plurality of cavities configured to receive the second plurality of the patient's teeth on the second jaw of the patient;
- and
- a second occlusal portion connected to the second plurality of cavities, the second occlusal portion comprising a second plurality of interfacing surfaces;
- wherein the first plurality of interfacing surfaces is configured to couple to the second plurality of interfacing surfaces so as to laterally couple the patient's first and second jaws to each other to distribute localized lateral impact forces, and
- wherein at least one of the first or second mouth guards comprises a multi-laminate material comprising a hard outer layer, a soft middle layer, and a hard inner layer.
A system that provides protection against impact-induced injuries during an orthodontic treatment, the system comprising:
- an aligner configured to reposition a plurality of a patient's teeth on a first jaw of the patient from a first arrangement toward a second arrangement different from the first arrangement;
- and
- a first mouth guard configured to protect the plurality of the patient's teeth, the first mouth guard comprising:
- a plurality of cavities configured to receive the plurality of the patient's teeth, wherein the plurality of cavities comprise an accommodation envelope providing a swept volume that accommodates the aligner when worn on the plurality of the patient's teeth, and wherein the swept volume accommodates at least one tooth of the plurality of the patient's teeth along a spatial path from a first location of the at least one tooth in the first arrangement to a second location of the at least one tooth in the second arrangement;
- and
- an occlusal portion having a first side and a second side opposite the first side, wherein the first side is adjacent to the plurality of cavities comprising the accommodation envelope providing the swept volume, and the second side is configured to interface with a second mouth guard worn on a second jaw of the patient so as to laterally couple the patient's first and second jaws to each other to distribute localized lateral impact forces.
