Patent number: 10517813Abstract: Methods for use in selectively conditioning and remineralizing teeth. An exemplary method comprises the steps of applying a conditioning composition to one or more of a person's teeth, and separately applying a remineralizing composition to the person's teeth. The conditioning composition includes a conditioning agent, and the remineralizing composition includes a remineralizing agent comprising calcium ions and/or fluoride ions. The conditioning composition may be applied prior to or after application of the remineralizing composition. In one embodiment, both the conditioning composition and the remineralizing composition include different remineralizing ions (e.g., one including calcium, one including fluoride).Type: GrantFiled: June 26, 2017Date of Patent: December 31, 2019Assignee: Ultradent Products, Inc.Inventors: Dan E.

Patent number: 10449123Abstract: Fluoride varnish compositions for temporary application and adhesion to a person's teeth include a carrier that remains stable and translucent during storage. The compositions include a carrier comprising a stable and translucent resin and a fluoride ion source (e.g., a fluoride salt such as sodium fluoride) dispersed within the carrier so as to provide biologically available fluoride ions to teeth being treated. The carrier resists formation of solids that can plug a 25 gauge (or 10 gauge) syringe brush applicator tip. The compositions may also include an adhesion promoting agent comprising an alkyl phosphoric acid. 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: December 27, 2017Date of Patent: October 22, 2019Assignee: ULTRADENT PRODUCTS, INC.Inventors: Peter M.

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: 10307049Abstract: Provided herein is a retraction device for retracting soft tissue from the dental surfaces in the oral cavity of a patient. The retraction device is comprised of a topology conformable structure, where the topology conformable structure is adaptable to be delivered to the oral cavity in a constrained shape. The device can then undergo a conformation change in the oral cavity, where the device transforms into its unconstrained shape. The unconstrained shape of the device creates a useable working field in the oral cavity. The useable working field can provide increased accessibility to and/or visibility within the oral cavity. Also provided herein are methods for using the device and kits.Type: GrantFiled: May 26, 2016Date of Patent: June 4, 2019Assignee: ULTRADENT PRODUCTS, INC.Inventors: Craig Hines, Curtis Pontynen

Patent number: 9949809Abstract: Non-customized dental treatment trays used to provide a desired treatment are formed from elastomeric silicone or silicone-like material. They may be molded from a two-part liquid silicone composition or a silicone-like TPE material (e.g., preferably SEBS and/or VERSAFLEX™ thermoplastic elastomer). The dental treatment trays possess high adaptability, flexibility, softness, and elastic elongation while also exhibiting resiliency in order to readily conform to the ridges, depressions and contours of a person's teeth during use. The trays possess a greater ability to adhere to a person's teeth compared to non-elastomeric thermoplastic materials. Due to their high adaptability and conformability, the non-customized dental trays behave like a semi-custom dental tray when placed over conformed to a person's teeth, particularly when used in combination with a sticky, viscous treatment composition.Type: GrantFiled: June 12, 2014Date of Patent: April 24, 2018Assignee: Ultradent Products, Inc.Inventors: Paul E.
