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.

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: Orthodontic systems and related methods are disclosed for designing and providing improved or more effective tooth moving systems for eliciting a desired tooth movement and/or repositioning teeth into a desired arrangement. Methods and orthodontic systems include the generation of an overcorrection in the tooth-receiving cavities of an appliance worn in the dentition. The overcorrection may provide an improved and more accurately applied force or moment applied to a tooth. The overcorrected force or moment can move a tooth closer to a desired position than if not overcorrected as sufficient force can still applied to the tooth as it gets closer to the desired position. The overcorrected force or moment may also better target the root of the tooth where the biological response to tooth movement occurs. The overcorrection may be calculated in various ways as described herein.

Abstract: Systems, methods, and devices for computer-aided design, digital treatment planning, and direct additive manufacturing of dental appliances are provided. In some embodiments, a method includes receiving a treatment plan for a patient's teeth, the treatment plan specifying a target arrangement for the teeth and a plurality of treatment stages to reposition the teeth from an initial arrangement toward the target arrangement. The method can include identifying appliance design parameters for one or more dental appliances to implement at least one treatment stage of the plurality of treatment stages. The appliance design parameters can include one or more manufacturability parameters corresponding to an additive manufacturing process to be used to directly fabricate the one or more dental appliances. The method can further include determining an appliance geometry for the one or more dental appliances using the set of appliance design parameters.
