Patent number: 10814000Abstract: A guided bone regeneration material is disclosed. The guided bone regeneration material includes biodegradable fibers produced by an electrospinning method. The biodegradable fibers produced by the method include a silicon-releasing calcium carbonate and a biodegradable polymer. The silicon-releasing calcium carbonate is a composite of siloxane and calcium carbonate of vaterite phase. The biodegradable fibers may be coated with apatite. When the guided bone regeneration material is immersed in a neutral aqueous solution, silicon species ions are eluted from the calcium carbonate. The guided bone regeneration material excels in bone reconstruction ability.Type: GrantFiled: December 20, 2018Date of Patent: October 27, 2020Assignees: NATIONAL UNIVERSITY CORPORATION NAGOYA INSTITUTE OF TECHNOLOGY, ORTHOREBIRTH CO., LTD., YAMAHACHI DENTAL MFG., CO., YABASHI INDUSTRIES, CO., LTD.Inventors: Toshihiro Kasuga, Yoshio Ota, Takashi Wakita

Patent number: 8834233Abstract: A method for producing an implant whose surface is roughened by the sandblast method using shot material containing fluoroapatite. Fluoroapatite, compared to hydroxyapatite, has poor biocompatibility, but is superior in hardness. It also has a property of being dissolved in acid. As a result, by the sandblast method using shot material containing fluoroapatite, the surface roughening is performed quite effectively, and shot materials remained on the surface can easily be removed by acid.Type: GrantFiled: December 9, 2008Date of Patent: September 16, 2014Assignee: Yamahachi Dental Mfg., Co.Inventors: Hideki Aoki, Masashi Toyama, Hiroto Fujimaki, Yuki Hashimoto

Publication number: 20100119564Abstract: Disclosed is a guided bone regeneration membrane including a novel mechanism that effectively induces a bone reconstruction ability. The mechanism is provided by forming a bi-layered structure of a first nonwoven fabric layer containing a silicon-releasable calcium carbonate and a poly(lactic acid) as principal components and a second nonwoven fabric layer containing a poly(lactic acid) as a principal component; and coating the first nonwoven fabric layer with an apatite. The guided bone regeneration membrane is available by using a nonwoven fabric manufacturing technique through electrospinning and a simulated body fluid soaking technique.Type: ApplicationFiled: November 13, 2009Publication date: May 13, 2010Applicants: NATIONAL UNIVERSITY CORPORATION NAGOYA INSTITUTE OF TECHNOLOGY, YABASHI INDUSTRIES CO., LTD., YAMAHACHI DENTAL MFG., CO.Inventors: Toshihiro Kasuga, Yoshio Ota, Takashi Wakita
