    Abstract: The present disclosure provides method, computing device readable medium, and devices for dental appliances with repositioning jaw elements. An example of a method can include identifying a misaligned jaw of a patient from a virtual image of the patient's jaw, providing a treatment plan for the patient including a virtual model of a dental appliance having a first shell and a second shell configured to reposition at least one tooth of the patient, and adjusting the position of the repositioning jaw elements on the first shell and the second shell to comply with a number of constraints. The virtual model of the dental appliance including repositioning jaw elements on the first shell and the second shell configured to move a position of the misaligned jaw of the patient.

    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.
