| titleOfInvention | Transparency-controllable artificial tooth material and preparation method thereof |
| abstract | The invention belongs to the technical field of material engineering, and relates to an artificial tooth material with controllable transparency and a preparation method thereof. The preparation method comprises the following steps: s1, dissolving polymethyl methacrylate (PMMA) and polymethacrylic acid (PMAA) in an acetone solution to obtain a mixed solution; s2, stirring the mixed solution for 24-48 hours, injecting the mixed solution into a mold under the condition that the environmental humidity is 25-75%, and standing until the acetone is completely volatilized to obtain the artificial tooth material. The preparation method can obtain the artificial tooth materials with different transparencies by setting different environmental humidities, and the transparencies of the artificial tooth materials are still adjustable. The artificial tooth material obtained by the preparation method is not easy to crack because no other components are added. |
