Antibacterial zirconia-based false tooth and preparation method thereof
The invention relates to the technical field of false teeth, in particular to an antibacterial zirconia-based false tooth and a preparation method thereof. The preparation method provided by the invention comprises the following steps: carrying out first mixing on part of zirconium oxide, part of yttrium oxide and part of coloring agent to obtain a first mixture; performing second mixing on the residual zirconium oxide, the inorganic antibacterial agent, the residual yttrium oxide and the residual coloring agent to obtain a second mixture; sequentially pouring the first mixture and the second mixture into a mold, and carrying out dry pressing to obtain an antibacterial composition ceramic block precursor with a multi-layer structure; and sequentially carrying out cold isostatic pressing, pre-sintering and final sintering treatment on the antibacterial composition ceramic block precursor to obtain the antibacterial zirconia-based false tooth, the second mixture is located at the gingival position of the antibacterial zirconia-based denture; the antibacterial zirconia-based false tooth is prepared from the following raw materials in parts by mass: 80-95 parts of zirconia, 1-5 parts of an inorganic antibacterial agent, 1-5 parts of yttrium oxide and 1-5 parts of a coloring agent. The antibacterial zirconia-based denture has antibacterial performance on oral streptococcus and has the effect of shielding the color of abutment teeth.
本发明涉及义齿技术领域，尤其涉及一种抗菌氧化锆基义齿及其制备方法。本发明提供的制备方法，包括：将部分氧化锆、部分氧化钇和部分着色剂进行第一混合，得到第一混合料；将剩余氧化锆、无机抗菌剂、剩余氧化钇和剩余着色剂进行第二混合，得到第二混合料；将所述第一混合料和第二混合料依次倒入模具中进行干压压制，得到具有多层结构的抗菌组合物瓷块前体；将所述抗菌组合物瓷块前体依次进行冷等静压、预烧结和终烧处理，得到所述抗菌氧化锆基义齿；所述第二混合料位于抗菌氧化锆基义齿的牙龈位置；按质量份数计，所述抗菌氧化锆基义齿包括以下制备原料：氧化锆80～95份、无机抗菌剂1～5份、氧化钇1～5份和着色剂1～5份。所述抗菌氧化锆基义齿对口腔链球菌具有抗菌性能，并具有遮蔽基牙颜色的效果。
