Abstract: A custom tool for forming a dental restoration in a mouth of a patient includes a one-piece mold body providing for a customized fit with at least one tooth of the patient, the one-piece mold body including an occlusal portion forming an occlusal surface corresponding with an occlusal surface of the tooth, a mesial proximal portion forming a mesial proximal surface corresponding with a mesial proximal surface of the tooth, and a distal proximal portion forming a distal proximal surface corresponding with a distal proximal surface of the tooth. The mold body is configured to combine with the tooth of the patient to form a mold cavity encompassing missing tooth structure of the tooth. The occlusal portion, the mesial proximal portion, and the distal proximal portion are based on three-dimensional scan data of the mouth of 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: 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 tool for forming a dental restoration includes a mold body configured to combine with a tooth of a patient to define a mold cavity encompassing at least a portion of desired tooth structure of the tooth. In some examples, the portion of desired tooth structure defines an interproximal surface of the tooth. The mold body may include, in some examples, a base member configured to provide a customized fit with at least one tooth of the patient to attach the mold body to the at least one tooth, and an interproximal member extending from the base member and configured to be disposed between adjacent teeth of the patient when the base member is fit over the at least one tooth. The interproximal member defines a surface of the mold cavity.
