    Abstract: Embodiments are provided for forming a patterned dental positioning appliance. One method includes forming a virtual shell shaped to receive one or more teeth of a virtual model of a patient's dentition, and digitally applying a pattern on an inner surface within cavities of the virtual shell, where the pattern contacts at least a portion of the one or more teeth and modifies repositioning forces exerted on the one or more teeth. In some cases the pattern is a raised pattern, such as a raised mesh pattern. In forming the dental appliance, in some cases, the shell and the pattern are formed of the same material to form a unitary piece of the polymer material.

    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: The present disclosure provides methods, computing device readable medium, and devices for dental appliances with repositioning jaw elements. An example of a method can include moving at least one tooth with a dental appliance having a first shell configured to receive a plurality of teeth of a patient's upper dentition and separating an upper dentition of a patient from a lower dentition of the patient utilizing the dental appliance. The dental appliance may interface a first surface of a first repositioning jaw element of the first shell with a second surface of a second repositioning jaw element of a second shell of the dental appliance. The dental appliance separates occlusal surfaces of the plurality of teeth of the patient's upper dentition from occlusal surfaces of the plurality of teeth of the patient's lower dentition as the patient moves to a fully engaged sagittal jaw position.

    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: An appliance comprises a passive component and an active force generating component, in which the active force generating component is configured to react to a stimulus and generate tooth movement forces. In some embodiments, the passive component is configured to deflect when placed on one or more teeth and generate tooth movement forces, which are combined with tooth movement forces of the force generating component. In some embodiments, the passive component comprises a polymer which is less reactive to the stimulus than the force generating component. The force generating component can be configured to increase force to one or more teeth at an appropriate time.
