Abstract: 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.

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: 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.
