    摘要: The invention relates to inorganic-organic compound substances useful for biomedical purposes. The object of the invention is to develop inorganic-organic compound materials which overcome the disadvantages of the state of art, wherein inorganic-organic compound substances for biomedical purposes possess to a large extent specifically adjustable characteristics. Inorganic initial substances form a new solid chemical compound with organic initial substances. The inorganic initial component consists of a biocompatible silicate glass and/or a silicate glass ceramic of the system SiO.sub.2 -Al.sub.2 O.sub.3 -MgO-Na.sub.2 O/K.sub.2 O-F.sup.-, and/or a bioactive phosphate silicate glass and/or a phosphate silicate glass ceramic of the system SiO.sub.2 -Al.sub.2 O.sub.3 -MgO-Na.sub.2 O/K.sub.2 O-CaO-P.sub.2 O.sub.5 F.sup.- and/or of the system SiO.sub.2 -MgO-K.sub.2 O-F.sup.- -CaO-P.sub.2 O.sub.5, and/or a bioactive phosphate glass and/or a phosphate glass ceramic of the system P.sub.2 O.sub.5 -Al.sub.2 O.sub.3 -CaO-Na.sub.2 O/K.sub.2 O, and/or a sintred ceramic based upon tricalcium phosphate and/or apatite. The organic initial component consists of a biocompatible, monomer-free, epoxidized polymeric hydrocarbon consisting only of the elements C, H, O having an average molecular weight Mn of 2,000 to 6,000 and an epoxy equivalence EEW of 50 to 500 g. The inorganic initial component is modified by phosphoric acid.

    摘要: A sheet-shape adhesive preparation for promoting tooth-movement in orthodontics comprising a layer of a pharmaceutical composition containing as the active ingredient a prostaglandin (e.g. prostaglandin E.sub.1, prostaglandin E.sub.2, and prostaglandin F.sub.2.alpha.) in admixture with one or more high molecular weight compounds and a flexible base sheet, a process for the preparation thereof, and a method for promoting tooth-movement in orthodontics by applying the sheet-shape adhesive preparation to the mucous membrane of gingiva. Said preparation can be kept for a long period of time without being dissolved in saliva and without irritation or unpleasant feeling when applied to the mucous membrane of gingiva and hence can show the tooth-movement activity of the active prostaglandin for a long period of time.

    摘要: Dental methods and materials are disclosed for treating diseased or traumatized teeth and peridontal tissues. Physiologically compatible and soluble calcium phosphate compounds are prepared into a porous aggregate paste or powder and positioned adjacent to calcified tissue in contact with a blood supply. Such a technique permits improved methods for pulp capping procedures, root canal procedures, tooth replanting procedures and for corrective peridontal procedures.
