Patent number: 8765837Abstract: [Problems] To provide a chemical polymerization type curable composition which can achieve a very large strength of adhesion even without irradiated with light, and is used in the field of dental therapy. [Means for Solution] A dental curable composition comprising (A) a polymerizable monomer component containing an acidic group-containing polymerizable monomer, (B) water, and (C) a chemical polymerization initiator component comprising a radical-generating species and a reactive species that generates radicals upon reacting with the radical-generating species; wherein, the dental curable composition is stored being divided into a plurality of packages, and is polymerized and cured by mixing together the components contained in the packages; and wherein one package (I) among the packages contains the component (A) and the component (B), and, further, contains polyvalent metal ions in an amount of 0.Type: GrantFiled: November 14, 2008Date of Patent: July 1, 2014Assignee: Tokuyama Dental CorporationInventors: Kyoichi Fujinami, Ayumi Dodomi, Koji Matsushige, Kazuhiko Okishio

Patent number: 8513327Abstract: An adhesive composition for dental use exhibiting acidic property, including a mixture of a polymerizable monomer component (A) containing a phosphoric acid-type polymerizable monomer having an acidic group derived from phosphoric acid, and a multivalent metal ion-releasing component (B), wherein the multivalent metal ion-releasing component (B) is capable of releasing at least earth metal ions, and in the composition, earth metal ions stemming from the component (B) are present together with the phosphoric acid-type polymerizable monomer in such an amount that a total valency ratio (RE) defined by the following formula (1) is in a range of 0.2 to 3.0. The adhesive composition is capable of strongly adhering and fixing a composite resin or a prosthetic material to a tooth for extended periods of time maintaining stability.Type: GrantFiled: November 8, 2007Date of Patent: August 20, 2013Assignee: Tokuyama Dental CorporationInventors: Koji Matsushige, Takeshi Suzuki, Shizuka Shimizu, Ayumi Dodomi

Patent number: 8104609Abstract: A container which is not bulky at the time of shipping and can be stably stood on a suitable place. The container includes a lid member for closing a take-out opening (brittle portion) of the container body 2. On the lower outer side of the container body, there are formed slits for fitting the lid member to the container body after the container body and the lid member are separated apart, and auxiliary leg portions that protrude outward of the container body. The lid member is forming holding leg portions that protrude outward therefrom. Wing portions of the holding leg portions are inserted in the slits to fit the lid member to the container body, and the erected attitude of the container body is supported by the holding leg portions.Type: GrantFiled: March 7, 2008Date of Patent: January 31, 2012Assignee: Tokuyama Dental CorporationInventors: Koji Matsushige, Masayuki Aizawa, Nobutoshi Yamaguchi, Ayumi Dodomi
