Abstract: Improved orthodontic appliances, along with related systems and methods, are provided. In one aspect, an appliance includes a shell having a plurality of cavities shaped to receive teeth, a discontinuity formed in the shell, and an elastic member positioned to interact with the discontinuity. In another aspect, an appliance includes a plurality of discrete shell segments joined by an elastic material to form a single appliance shell. In another aspect, an appliance includes a shell having an exterior layer and an interior layer having a stiffness less than a stiffness of the exterior layer, and a discontinuity formed in the exterior layer. In another aspect, an appliance includes a shell comprising an interior surface and an exterior surface, and an elastic coating covering at least a portion of one or more of the interior surface or exterior surface of the shell.

Abstract: A method includes to receive, via a computing device, data representing a plurality of teeth, identify data indicating which of the plurality of teeth are unerupted or erupting, predict at least one characteristic of a tooth of the unerupted or erupting teeth after they have fully erupted using one or more tooth eruption prediction factors, generate new data representing the unerupted or erupting teeth in multiple states of eruption based upon the predicted at least one characteristic of the fully erupted teeth, and generate a series of incremental tooth arrangements with the new data to define a proposed orthodontic treatment based on the new data representing the unerupted or erupting teeth in multiple states of eruption.

Abstract: A series of appliances including a first shell and a second shell can be designed to incrementally implement a treatment plan. The first and second shells can have cavities designed to receive teeth of a jaw. A first number of bite adjustment structures can be formed of a same material as the first shell, extending therefrom and designed to interface with teeth of a second jaw. The first number of bite adjustment structures can have a first shape and location specific to a first stage of the treatment plan. A second number of bite adjustment structures can be formed of a same material as the second shell, extending therefrom and designed to interface with teeth of the second jaw. The second number of bite adjustment structures can have a second shape and location, different than the first shape and location, specific to a second stage of the treatment plan.

Abstract: Aligners and associated systems are provided. In some embodiments, an aligner includes a three-dimensionally (3D) printed shell. The 3D printed shell can include an interior surface having a plurality of tooth-receiving cavities shaped to reposition a patient's dentition from a first arrangement toward a second arrangement, and an exterior surface disposed opposite the interior surface. The aligner can also include one or more elastic regions directly fabricated on the 3D printed shell. When the aligner is worn on the patient's dentition, the aligner can apply one or more forces onto the patient's dentition via the one or more elastic regions to affect repositioning of the patient's dentition from the first arrangement toward the second arrangement.

Abstract: An orthodontic appliance can include a shell having a plurality of cavities shaped to receive a patient's teeth is disclosed. The orthodontic appliance may comprise an interior surface and an exterior surface, and an elastic coating covering at least a portion of one or more of the interior surface or exterior surface of the shell. A stiffness of a portion of the orthodontic appliance corresponding to the portion of the shell covered by the elastic coating can be determined by a stiffness of the elastic coating.
