Patent number: 10369085Abstract: Dental cement compositions (including two-part compositions), kits, and related methods are used for bonding a dental prosthetic appliance to a tooth. A first part includes an amine activator component and a zinc oxide reactive filler, while a second part includes a polymerization initiator (e.g., benzoyl peroxide) and a polymerizable component having a structure including at least one acrylate or methacrylate group at one end and a carboxylic acid group at another end. A temporary cement composition advantageously exhibits reduced compressive and/or bonding strength relative to permanent cement compositions, which provides sufficient strength to facilitate normal use of the teeth while the provisional appliance is in use, while also facilitating easy removal of the provisional appliance for replacement with a permanent appliance at a later time.Type: GrantFiled: January 30, 2018Date of Patent: August 6, 2019Assignee: ULTRADENT PRODUCTS, INC.Inventors: Gordon Kennard, Andy T.

Patent number: 8852561Abstract: Fluoride varnish compositions for temporary application and adhesion to a person's teeth. The composition includes a carrier comprising a resin and an adhesion promoting agent comprising an alkyl phosphoric acid. A fluoride ion source (e.g., a fluoride salt such as sodium fluoride) is dispersed within the carrier so as to provide biologically available fluoride ions to the tooth tissue being treated. The composition adheres only temporarily to tooth tissue (e.g., for a period of at least about 4 minutes, but not more than about 1 year), after which the composition spontaneously wears away as a natural result of the action of the tongue, saliva and/or other factors.Type: GrantFiled: February 7, 2013Date of Patent: October 7, 2014Assignee: Ultradent Products, Inc.Inventors: Jeff A. Wagner, Andy T. Kawamoto

Publication number: 20080206715Abstract: Methods, compositions, and kits for use in facilitating detection and removal of dental adhesives while minimizing and/or eliminating removal of adjacent tooth tissue. A pH sensitive color changing component (i.e., an acid/base indicator) is included within a dental adhesive composition or an activating wash composition. The adhesive composition is used to bond a dental appliance (e.g., a provisional restorative appliance or an orthodontic bracket) to a tooth. When it becomes necessary to remove the dental appliance, selective removal of the dental adhesive while minimizing and/or eliminating removal of enamel or other adjacent tooth tissue are facilitated because of the inclusion of a pH sensitive color-changing component within the dental adhesive or activating wash composition. The adhesive changes from a first color having low contrast relative to adjacent tooth tissue to a second color having greater contrast relative to adjacent tooth tissue upon application of the activating wash.Type: ApplicationFiled: February 28, 2007Publication date: August 28, 2008Applicant: Ultradent Products, Inc.Inventors: Andy T.
