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: Improved systems, methods, and devices for treating sleep apnea are provided herein. In one aspect, an intraoral appliance for treating sleep apnea in a patient comprises an appliance shell comprising a plurality of cavities shaped to receive teeth of a jaw of the patient. The appliance shell can comprise an advancement structure arranged to interact with an opposing jaw of the patient so as to displace the lower jaw anteriorly relative to the upper jaw. The plurality of cavities can comprise cavity geometries shaped to reduce repositioning of one or more received teeth elicited by displacement of the lower jaw anteriorly relative to the upper jaw.

Abstract: The present disclosure includes dental appliances and methods of making and using such appliances. One method for forming a dental appliance includes forming a liquid thermoset polymer material into a semi-solid first shape, thermoforming the semi-solid first shape of thermoset polymer material onto a dentition mold, and curing the thermoset polymer on the dentition mold with a curative trigger to complete a molecular cross-linking reaction.

Abstract: The present disclosure provides method, systems, and devices for adjusting an arch of teeth. An appliance includes a removable shell formed of a first material having a number of cavities formed therein, wherein the number of cavities are shaped to receive teeth of a patient, and an arch element extending from the removable shell in a lingual direction and across at least a portion of the arch width of the removable shell, wherein the arch element is designed to expand an arch of the teeth of the patient, wherein the arch element has a width specific to a stage of a treatment plan.

Abstract: A dental appliance having an integrally formed reservoir and/or an ornamental design integrated thereon. The ornamental design can be selected or customized by a patient. The design can be created by directing energy to the dental appliance to alter a material property of at least a portion of the appliance to create the design. Alternatively, a groove or recess can be formed on a surface of the appliance to either mechanically retain an ornamental design or the groove or recess can be filled with ink to form the design. The appliance, including the integrally formed reservoir, can be formed using direct fabrication techniques.
