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.

Abstract: This disclosure provides low-viscosity resins for producing polymers with properties suitable for use in various mechanical appliances, such as orthodontic appliances (e.g., aligners). The low-viscosity resins may be photo-curable and can be used with direct fabrication methods and equipment. In various embodiments, the polymeric materials produced from the low-viscosity resins described herein have high toughness while remaining resistant to stress relaxation. Low-viscosity, photo-curable resins described herein have reduced hydrogen bonding in comparison to traditional materials (e.g., materials having high urethane content) used in orthodontic appliances.

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.
