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: A method for fabricating an oral appliance may include forming, using a 3D additive manufacturing process, a polymeric shell having a plurality of teeth engaging structures shaped to engage the teeth of the patient and forming, using the 3D additive manufacturing process, a force generating component coupled to the plurality of teeth engaging structures, the force generating component may be configured to generate a force in response to a stimulus in order to reposition one or more teeth of the patient. The polymeric shell, the plurality of teeth engaging structures, and the force generating component may include a sequentially polymerized plurality of layers directly fabricated together using the 3D additive manufacturing process.

Abstract: Methods of forming a dental appliance. The methods may include partially curing a prepolymer mixture into a semi-solid polymer material having a first shape that is a sheet. The semi-solid polymer material may be placed over a dentition mold, wherein the semi-solid polymer material may take on a second shape corresponding to a shell having one or more cavities for receiving one or more teeth. The semi-solid polymer material may be fully cured by exposure to energy until the semi-solid polymer material thermosets in the second shape.

Abstract: Patterned dental positioning appliances including a shell having cavities shaped to receive and exert repositioning forces on one or more teeth of a subject's dentition. The shell may include a first cavity having a first raised pattern configured to exert a first force on a first tooth of the one or more teeth, and a second cavity having a second raised pattern configured to exert a second force on a second tooth of the one or more teeth. The second raised pattern may be different than the first raised pattern.

Abstract: Dental appliances and methods for expanding the lower dental arch. The appliances may be removable mandibular expander devices for efficient arch expansion while being comfortable to wear and easy to use. The appliances may include a lingual portion that is shaped and sized to apply an expansion force to lingual surfaces of one or more teeth. The shape and size of the lingual portion may be configured to distribute the forces among posterior and/or anterior teeth. A series of expander devices may be designed to provide the expansion forces in a stepwise fashion toward a target lower arch configuration according to a treatment plan
