| titleOfInvention | Dental prosthetic material and preparation method thereof |
| abstract | The invention discloses a dental prosthetic material and a preparation method thereof. The method comprises the following steps of (1) immersing dentin in an EDTA aqueous solution; and (2) putting the dentin treated by the step (1) in a sodium hyaluronate-calcium nitrate hydrogel, adding a dihydrogen phosphate ion and fluoride ion aqueous solution after standing; and reacting to obtain the dental prosthetic material, wherein the sodium hyaluronate-calcium nitrate hydrogel is a mixture of sodium hyaluronate and calcium nitrate aqueous solutions. With the preparation method provided by the invention, a dense dental prosthetic material with a bionic structure analogous to human enamel is grown on the surface of the isolated human dentin directly under an environment similar to human physiological conditions (37 DEG C, atm, pH6.0) through a simple chemical method. The film dental prosthetic material has an extremely similar structure to that of natural human enamel and has apatite hexagonal prism crystals and enamel crystal column microstructures. Mechanical properties of the dental prosthetic material are between that of natural human enamel and that of the dentin. |
