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: Methods of forming dental appliances. The methods may include partially curing a prepolymer mixture in a first mold to form a partially cured polymer mixture. The first mold may have an internal cavity that is shaped to provide the partially cured polymer mixture with a first shape having a channel in accordance with a dental arch. The first shape may have a greater thickness at locations corresponding to where a gingival line of the dental appliance will be formed compared to a thickness at occlusal surfaces of the dental appliance. The methods may include modifying the first shape of the partially cured polymer mixture to form a shell having cavities shaped to receive teeth. The methods may also include fully curing the shell by exposing the partially cured polymer mixture to energy until the partially cured polymer mixture thermosets.

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: Embodiments are provided for forming a patterned dental positioning appliance. One method includes forming a virtual shell shaped to receive one or more teeth of a virtual model of a patient's dentition, and digitally applying a pattern on an inner surface within cavities of the virtual shell, where the pattern contacts at least a portion of the one or more teeth and modifies repositioning forces exerted on the one or more teeth. In some cases the pattern is a raised pattern, such as a raised mesh pattern. In forming the dental appliance, in some cases, the shell and the pattern are formed of the same material to form a unitary piece of the polymer material.
