Zirconia-based all-ceramic false tooth and preparation method thereof
The invention relates to a zirconia-based all-ceramic false tooth and a preparation method thereof. A core layer of the zirconia-based all-ceramic false tooth is prepared from the following components in parts by mass: 90 to 94 parts of ZrO2, 5 to 9 parts of Y2O3, 0.1 to 0.5 part of Al2O3, 0.01 to 0.5 part of Fe2O3, 0.01 to 0.5 part of Er2O3 and 0 to 0.2 part of MnO2, and a shell layer of the zirconia-based all-ceramic false tooth is prepared from the following components in parts by mass: 24.5 to 49.5 parts of CaCO3, 45 to 50 parts of SiO2, 0 to 25 parts of MgO, 0.01 to 0.5 part of Fe2O3, 0.01 to 0.5 part of Er2O3 and 0 to 0.2 part of MnO2. The preparation process comprises the following steps: performing dry pressing and isostatic pressing on raw materials of the core layer, presintering, and carving to obtain a zirconia-based false tooth biscuit; meanwhile, calcining raw materials of a shell layer, then adding deionized water, a dispersing agent and an adhesive, and carrying out ball milling and mixing to obtain calcium-magnesium-silicon-based ceramic slurry; and coating the calcium-magnesium-silicon-based ceramic slurry on the surface of the zirconium oxide-based false tooth biscuit, and sintering to obtain the zirconium oxide-based all-ceramic false tooth provided by the invention. The zirconia-based all-ceramic false tooth has good jade texture and is closer to the natural color of natural teeth.
本发明是一种氧化锆基全瓷义齿及其制备方法，其核层的质量份数组成为：ZrO2占90～94份，Y2O3占5～9份，Al2O3占0.1～0.5份，Fe2O3占0.01～0.5份，Er2O3占0.01～0.5份，MnO2占0～0.2份，其壳层的质量份数组成为：CaCO3占24.5～49.5份，SiO2占45～50份，MgO占0～25份，Fe2O3占0.01～0.5份，Er2O3占0.01～0.5份，MnO2占0～0.2份。制备过程如下：将核层的原材料经过干压与等静压，预烧结后雕刻得到氧化锆基义齿素坯；同时将壳层的原材料进行煅烧，随后加入去离子水与分散剂及粘合剂球磨混合后获得钙镁硅基陶瓷料浆；将钙镁硅基陶瓷料浆包覆在氧化锆基义齿素坯的表面并进行烧结，即获得本发明的氧化锆基全瓷义齿。本发明的氧化锆基全瓷义齿具有良好的玉质感，更接近天然牙齿的本色。
