Abstract: Described herein are attachments for an orthodontic appliance, such as an aligner, that include a base region configured to be rigidly mounted to a tooth surface and an interface surface region that is configured to engage with the orthodontic appliance, in which the base region and the interface surface region are movably connected. These attachments may be configured as force applying attachments and/or as force redirecting attachments. Also described herein are modular attachments.

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 method for determining biting occlusion of a patient's teeth including generating a first 3D digital model of the patient's lower arch in non-occlusion. A second 3D digital model of the patient's upper arch in non-occlusion may be generated. A third 3D digital model of the patient's upper and lower arches in biting occlusion may be generated. The first and second 3D digital models May be aligned with corresponding teeth of the third 3D digital model to generate a fourth 3D model of the patient's teeth in biting occlusion.

Abstract: A system and method for determining a center of resistance of a tooth may include receiving a 3D digital representation of an initial arrangement and a final arrangement of a patient's teeth and determining a 3D treatment plan. The 3D treatment plan may include a plurality of 3D stages for rearranging the teeth from the initial arrangement toward the final arrangement. The method may also include determining, in accordance with the 3D treatment plan, an intended movement of the teeth for each of the stages and deriving, using a 3D resistance model, an applied force system for achieving the intended movement of the teeth for each of the stages. The method may also include deriving 3D geometries of oral appliances for the stages in response to the applied force system. Various other systems and methods are also disclosed.
