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.

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.

Dental attachment positioning apparatuses and methods of use. A dental attachment apparatus may include an orthodontic attachment having a surface shaped to conform to a contour of a buccal surface of a tooth, and one or more registration surfaces that are shaped to conform to one or more occlusal surfaces of the patient's teeth. The one or more registration surfaces may be configured to aid in proper positioning or orientation of the orthodontic attachment. When the attachment positioning apparatus is placed on the patient's dentition, the orthodontic attachment is positioned at a specified location with respect to the buccal surface of the tooth.

Dental attachment positioning apparatuses

A dental appliance for positioning a patient's teeth includes a removable orthodontic tooth positioning appliance having teeth receiving cavities shaped to directly receive at least some of the patient's teeth and apply a resilient positioning force to the patient's teeth. The appliance includes a hard polymer layer having a hard polymer layer elastic modulus disposed between a first soft polymer layer having a first soft polymer layer elastic modulus and a second soft polymer layer having a second soft polymer layer elastic modulus. The hard polymer layer elastic modulus is greater than each of the first soft polymer layer elastic modulus and the second soft polymer layer elastic modulus. At least one of the first soft polymer layer and the second soft polymer layer has a flexural modulus of greater than about 35,000 psi.

Multilayer dental appliances and related methods and systems

Systems, methods, and devices for post-processing additively manufactured objects are disclosed herein. In some embodiments, a system includes a plurality of containers configured to receive a plurality of additively manufactured object having excess material thereon. The system can include a rotor having a central shaft and a plurality of arms, each arm having a first end and a second end opposite the first end. The first end of each arm can be coupled to the central shaft and a second end of each arm can be coupled to a respective container of the plurality of containers. The system can also include an actuator configured to spin the rotor so as to remove the excess material from the plurality of additively manufactured objects. The system can further include at least one heat source carried on the rotor to heat the excess material to decrease a viscosity thereof.

Orthodontic attachment devices for interacting with an orthodontic appliance. An anchoring attachment body may include first and second anchoring attachment regions connected by a connection region. The first and second anchoring attachment regions may be oriented differently such that their respective orthodontic appliance engagement surfaces are oriented in different directions. The connection region may include a first coupling end coupled to the first anchoring attachment region that is narrower than the first anchoring attachment region along a plane that is parallel to a bonding surface of the first anchoring attachment region. The connection region may have dimensions that define the positions of the first and second anchoring attachment regions and define orientations of the orthodontic appliance engagement surfaces so as to maintain set positions and orientations of the first and second anchoring attachment regions.

Orthodontic attachment devices

The present disclosure provides methods, devices, and systems for the bonding of attachments for use with dental appliances. For instance, an attachment template tray system may include a template body and a light source tray. Electronic circuitry of the light source tray may be configured to activate, based on a signal from a sensor assembly, radiation source(s) of the light source tray when the light source tray is within a threshold distance of the template body. The template body may include an orthodontic attachment with a release layer covering an engagement surface. Radiation sources of the light source tray may be configured to emit a first range of wavelengths of light for curing a light curable adhesive coating on the orthodontic attachment and a second range of wavelengths of light for degrading the release layer.

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.
