Abstract: A removable dental appliance may include an appliance body configured to at least partially surround a plurality of teeth. The appliance body may include a unitary material defining a shell shaped to receive at least one tooth of the patient; a spring member integrally formed with the shell; and a positioning member integrally formed with the shell. The spring member may be configured to receive an attachment affixed to the at least one tooth. The spring member may be configured to apply a spring force to the attachment to cause movement of the at least one tooth toward a desired position when the removable dental appliance is worn by the patient. The positioning member may be configured to facilitate engagement of the spring member with the attachment in response to a positioning force being applied to the positioning member.

Abstract: A custom tool for forming a dental restoration in a mouth of a patient includes a first mold body providing for a customized fit with at least one tooth of the patient. The first mold body includes a portion corresponding with at least a first surface of the tooth and an interproximal portion corresponding with an interproximal surface of the tooth, the interproximal portion being of unitary construction. The first mold body is configured to combine with the tooth of the patient to form a mold cavity encompassing a first portion of missing tooth structure of the tooth.

Abstract: A removable dental appliance may include an appliance body configured to at least partially surround a plurality of teeth of a dental arch of a patient. The appliance body may include a unitary material defining a shell shaped to receive at least one tooth of the patient and a spring member integrally formed with the shell. The spring member may be configured to receive an attachment. The attachment may be configured to affix to the at least one tooth. The spring member may be configured to apply a spring force to the attachment to cause at least one of a rotation, a translation, a tipping, a torqueing, an extrusion, or an intrusion of the at least one tooth toward a desired position of the tooth when the removable dental appliance is worn by the patient.

Abstract: The present disclosure provides an aqueous dispersion. The aqueous dispersion includes a) water; b) a surfactant having at least one ethylenically unsaturated group; and c) polyester particles dispersed in the water. The polyester particles include a water-insoluble polyester having a weight average molecular weight of 20 kiloDaltons or greater, and the polyester particles have an average diameter that is submicron in size. Further, the present disclosure provides a method of making the aqueous dispersion. The method includes a) dissolving a water-insoluble polyester in a water-immiscible solvent to form a polyester solution; b) combining the polyester solution with an aqueous solution including water and a surfactant; and c) removing at least a portion of the water-immiscible solvent to form the aqueous dispersion including polyester particles dispersed in the water. The present disclosure also provides a photopolymerizable composition including a) water; b) a surfactant; c) polyester particles dispersed in the water; d) a photoinitiator; e) at least one ethylenically unsaturated monomer dispersed in the water; and f) an optional polymerization inhibitor. The present disclosure also provides coatings and articles prepared from the aqueous dispersion or photopolymerizable composition.

Abstract: Various embodiments of an orthodontic appliance and method of forming such appliance are disclosed. In one or more embodiments, the orthodontic appliance can include an arch member including an arch member body and an arch member coupling connected to the body. The orthodontic appliance can also include an anchor including an anchor coupling and a base adapted to connect the anchor to a surface of a tooth. The arch member coupling can be releasably connectable to the anchor coupling, and the anchor can be adapted for displacement relative to the arch member body when the anchor is connected to the surface of the tooth and the arch member coupling is connected to the anchor coupling.

Abstract: Techniques are described for automating the design of dental restoration appliances using neural networks. An example computing device receives transform information associated with a current dental anatomy of a dental restoration patient, provides the transform information associated with the current dental anatomy of the dental restoration patient as input to a neural network trained with transform information indicating placement of a dental appliance component with respect to one or more teeth of corresponding dental anatomies, the dental appliance being used for dental restoration treatment for the one or more teeth, and executes the neural network using the input to produce placement information for the dental appliance component with respect to the current dental anatomy of the dental restoration patient.
