摘要:
PROBLEM TO BE SOLVED: To provide tooth-plane restorative materials having excellent tooth-plane repairing ability.SOLUTION: The present invention relates to a tooth-plane restorative material comprising ceramic particles, the ceramic particle having a particle diameter of 10 to 700 nm, the ceramic particle being a calcium phosphate sintered body particle, and the ceramic particle containing no calcium carbonate. The ceramic particle has the maximum diameter of a minor axis of 30 nm to 5 μm and the major axis of 75 nm to 10 μm, grows up to c axial direction, as well as has the aspect ratio (c axial length/a axial length) of a crystal of 1 to 30.SELECTED DRAWING: None【課題】優れた歯面修復能を有する歯面修復材の提供。【解決手段】セラミック粒子を含む歯面修復材において、前記セラミック粒子の粒子径が、10~700nmの範囲内であり、前記セラミック粒子が、リン酸カルシウム焼結体粒子であり、前記セラミック粒子が、炭酸カルシウムを含有しない歯面修復材。前記セラミック粒子の粒子径が短軸の最大値径が30nm~5μmで長軸が75nm~10μmでc軸方向に成長し、結晶のアスペクト比(c軸長/a軸長)が、1~30である歯面修復材。【選択図】なし
