Patent number: 10238476Abstract: A method of attaching a dental article to the surface of a tooth includes providing the dental article and applying a coating including upconversion phosphors to a surface of the dental article. The method also includes applying a dental cement composition to the surface of the tooth and placing the dental article on the surface of the tooth such that the coating is adjacent the dental cement composition. The dental cement composition includes a polymerizable resin and a photoinitiator and is substantially free of upconversion phosphors. The method further includes irradiating the coating with a radiation source that emits radiation at a pre-determined fixed wavelength that causes the upconversion phosphors to emit radiation at an activation wavelength of the dental cement composition photoinitiator such that the dental cement composition cures in a region adjacent the coating and removing remaining uncured dental cement composition outside the dental article from the tooth.Type: GrantFiled: May 2, 2017Date of Patent: March 26, 2019Assignee: DENTSPLY SIRONA INC.Inventors: Naim Karazivan, Hui Lu, Thomas Ertl

Patent number: 9675435Abstract: A luminescent coating is disclosed that is used to dimensionally control the curing of a photocurable agent placed in close contact with the coating. The coating is applied at the interface of structures, such as brackets and prosthetics, or may be applied directly on a curable material for use in 3D printing, at the location where bonding material is needed to be cured. The luminescent coating irradiates from its structure the curing radiations necessary to photopolymerize the resin in response to a first radiation irradiated on its structure of a different wavelength.Type: GrantFiled: December 31, 2014Date of Patent: June 13, 2017Assignee: Dentsply Sirona Inc.Inventors: Naim Karazivan, Hui Lu, Thomas Ertl
