Abstract: Apparatuses and methods for monitoring the performance of an orthodontic appliance for repositioning a patient's teeth. An orthodontic appliance may include a plurality of teeth receiving cavities shaped to reposition the patient's teeth from an initial arrangement towards a target arrangement, and one or more sensors configured to determine tooth movement (based on position and/or orientation) and/or forces applied to the teeth. The sensor may be distributed between attachments and aligners that mate with the attachments.

Abstract: Methods and apparatus for producing controlled tooth-moving forces are provided. An orthodontic appliance includes one or more occlusal surface features that modify bite forces between opposing teeth during intercuspation to aid in realignment of the teeth. The interception bite forces can be applied between appliance shells on opposing arches, or between an appliance shell and an opposing tooth. These modified bite forces can be used to supply or augment tooth-moving forces, and the tooth moving forces can produce moments to urge rotational movement of a tooth. Also described herein are orthodontic appliances having an occlusal outer surface contours that are distinct from the occlusal inner surface contour within the dental appliance and may be configured to selectively intercuspate.

Abstract: 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.

Abstract: An orthodontic alignment device can have a palatal contour anchorage (PCA) feature that generally matches the shape of the patient's hard pallet. This PCA feature may be built slightly off-set to deliberately push against the patient's palate and/or gingiva to provide anchorage support of staged translation of the teeth. By transferring the required anchorage away from the teeth and onto the palate, through the PCA feature, the adjacent teeth are no longer subjected to unwanted side effects of reaction forces.
