Patent number: 8420708Abstract: Methods for making dental crowns, bridges, inlays, onlays, veneers, fillings, and other restorations are provided. The methods involve using a two-phase light curing (TPLC) material. Preferably, the TPLC material used to form the dental restoration comprises a blend of polymerizable compounds; photopolymerization systems (a) and (b), and particulate filler materials (a) and (b). In a first light-curing step, curing light having a wavelength of greater than 420 nm is used to activate system (a). In a second light-curing step, curing light having a wavelength of less than 420 nm is used to activate system (b). The two step light-curing method is efficient and allows the dentist to make restorations having high mechanical strength and pleasing aesthetics.Type: GrantFiled: April 5, 2011Date of Patent: April 16, 2013Assignee: DENTSPLY International Inc.Inventor: Fuming Sun

Publication number: 20110027759Abstract: The invention provides a method of forming dental restorations, particularly dental crowns. The method involves applying a flexible spacer material having a polymerization system capable of being activated by light to a prepared tooth surface. A composite crown-forming material is dispensed into a transparent plastic matrix. The matrix is placed in the mouth of the patient so the composite material is molded over the tooth surface coated with the spacer material. Then, the composite is irradiated with curing light, through the matrix, so that it hardens to form a dental crown. The crown is removed, trimmed and finished, and then permanently affixed to the tooth.Type: ApplicationFiled: October 14, 2010Publication date: February 3, 2011Inventors: Walter R. Dias, Fuming Sun, Robert V. Hare

Patent number: 7494339Abstract: The invention provides a method of forming dental restorations, particularly dental crowns. The method involves applying a flexible cement composition to a prepared tooth surface. The composition is polymerized so that it substantially hardens. A composite crown-forming material is dispensed into a substantially transparent plastic matrix. The matrix is placed in the mouth of the patient so that the composite material is molded over the tooth surface. Then, the material is irradiated with curing light, through the matrix, so that it hardens to form a dental crown. The crown has good mechanical strength and is resistant to fracturing and breaking.Type: GrantFiled: August 10, 2006Date of Patent: February 24, 2009Assignee: Dentsply International, Inc.Inventors: Walter R. Dias, Fuming Sun, Robert V. Hare

Publication number: 20070100019Abstract: The present invention relates generally to dental compositions containing polymerizable resins and a catalyst system for accelerating polymerization and hardening of the resins. The composition is prepared from two parts—a base paste containing a polymerizable resin and thiourea compound that acts as a polymerization accelerator and a catalyst paste containing thermally stable hydroperoxide compounds. The dental compositions can be used as crown and bridge materials inlays, onlays, veneers, fillings, sealants, adhesives, cements, and other dental materials.Type: ApplicationFiled: July 27, 2006Publication date: May 3, 2007Inventor: Fuming Sun

Patent number: 5834526Abstract: Microspheres are described which have a shell of thermally expandable polymer and a hollow interior that contains a fluorinated hydrocarbon that boils at a temperature below the melting point of the polymer, and contains an organic ester or ether or ketone. The ester or ether or ketone improves the quality of microsphere product. The expandable particles are useful in insulation, packaging, for expanding other polymer such as polytetrafluoroethylene, and the like.Type: GrantFiled: July 11, 1997Date of Patent: November 10, 1998Inventors: Huey S.
