Patent number: 11964030Abstract: The present disclosure provides a root-canal sealer composition including cement and a hygroscopic liquid, in which the cement includes tricalcium silicate (3CaO·SiO2) in which an aluminum atom (Al) is solid-soluted (Al solid-soluted C3S), dicalcium silicate (2CaO·SiO2) in which an aluminum atom (Al) is solid-soluted (Al solid-soluted C2S), and tricalcium aluminate (3CaO·Al2O3) in which a silicon atom (Si) is solid-soluted (Si solid-soluted C3A), the tricalcium aluminate being disposed between at least one selected from the group consisting of the Al solid-soluted C3S and the Al solid-soluted C2S. When the cement including aluminum solid-soluted tricalcium silicate, aluminum solid-soluted dicalcium silicate, and silicon solid-soluted tricalcium aluminate is prepared and used for a root-canal sealer composition, a curing time is reduced and compressive strength is increased.Type: GrantFiled: August 1, 2019Date of Patent: April 23, 2024Assignee: VERICOM CO., LTD.Inventors: Myunghwan Oh, Dohyun Kim, Jongho Kang, Jiyeon Suh, Yunki Kim

Patent number: 11744684Abstract: Proposed is a method of manufacturing a dental composite blank. The method of manufacturing the dental composite blank includes (a) pressurizing a laminate for a composite blank having multiple layers having different colors at a first pressure (P1), (b) pressurizing the laminate for a composite blank, pressurized at the first pressure, at a second pressure (P2), and (c) manufacturing a composite blank by curing the pressurized laminate for a composite blank, in which steps (a) and (b) are each independently performed once or multiple times, and the first pressure (P1) is less than or greater than the second pressure (P2), ultimately making it possible to manufacture a dental composite blank that is similar to a natural tooth and thus exhibits a superior aesthetic appearance and high interlayer bonding strength.Type: GrantFiled: December 20, 2019Date of Patent: September 5, 2023Assignee: VERICOM CO., LTD.Inventors: Myung-Hwan Oh, Jong-Ho Kang, Hyun-Chul Yoo, Yun-Ki Kim

Patent number: 8956629Abstract: Disclosed is a dental composition, comprising unsaturated double bond-containing monomers and/or oligomers, a catalytic amount of polymerization initiator to initiate polymerization, and a filler, wherein the dental composition comprises an organic nanotube containing an antibacterial or anticariogenic material to inhibit or prevent tooth decay. The dental composition comprises an organic nanotube containing an antibacterial or anticariogenic material, thus uniformly and continuously exhibiting anticariogenic and antibacterial activities, while avoiding deterioration in physical properties required for the dental material.Type: GrantFiled: May 19, 2008Date of Patent: February 17, 2015Assignee: Vericom Co. LtdInventors: Myung-Hwan Oh, Won-Ho Kim, Mi Hyoun Ham, Jong-Hwi Lee, Yun-Ki Kim
