Beschreibung
Zusammenfassung:	PURPOSE:To improve ordinary temp. caking properties and to attempt to improve strength without spoiling workability by forming a biomaterial being useful as a hard system replacing material having biocompativility from a powder wherein calcium phosphate compd. is a main ingredient and a soln. wherein fine particles of a metal oxide are dispersed in water. CONSTITUTION:A biomaterial being suitable for curing and repairing of a loss or cavity part of a tooth in the dental region consists of a powder wherein calcium phosphate is a main ingredient and a soln. wherein using water as a dispersing medium, fine particles of a metal oxide are coloidally dispersed in water. As the calcium phosphate compd., alpha-type tricalcium phosphate and tetracalcium phosphate are pref. used and as the metal oxide, silicic anhydride, zirconia and zircon are used. In addition, the soln. is a mixture of a colloidal soln. of at least one among silicic anhydride, zirconia and zircon and a colloidal soln. of another metal oxide. This biomaterial is cured by being accompanied with conversion to hydroxyapatite.
