Zusammenfassung: | The invention discloses a dental prosthetic material and a preparation method thereof. The preparation method comprises the following steps of: 1) soaking substantia adamantina dentis, dentinum or titanium sheets with a phosphoric acid solution or a mixed solution of hydrogen peroxide and phosphoric acid, so as to obtain treated substantia adamantina dentis, dentinum or titanium sheets; and 2) mixing calcium nitrate hydrogel with an aqueous solution of phosphate anions and fluorine ions so as to obtain a mixed solution, soaking the treated substantia adamantina dentis, dentinum or titanium sheets with the mixed solution, and performing reaction, thereby obtaining the dental prosthetic material. A compact dental prosthetic material with a human substantia adamantina dentis bionic structure grows under an environment approximate to human body physiologic conditions. The dental prosthetic material has a hydroxylapatite hexagonal prisms crystal and substantia adamantina crystalline column microstructure and has m |
