Medical composite ceramic material and preparation method thereof
The invention provides a medical composite ceramic material and a preparation method thereof, the medical composite ceramic material comprises at least three ceramic layers of which the colors changein a gradient manner from deep to light from neck to a cut end, and the color gradient difference between two adjacent ceramic layers is less than or equal to 10%; the ceramic layer comprises zirconium oxide ceramic powder, a coloring agent, light-cured resin, a photoinitiator and an auxiliary agent; the total mass of the zirconium oxide ceramic powder and the coloring agent of each ceramic layeris calculated according to 100wt%, the zirconium oxide ceramic powder in the neck ceramic layer accounts for 80-90wt%, and the rest is the coloring agent; zirconium oxide ceramic powder contained in each ceramic layer from the neck to the cut end is progressively increased according to the equal gradient of 5-10 wt%. The color of the prepared ceramic material is in gradient change, the color transition is natural and is close to the color distribution characteristic of natural teeth, the preparation process is simple, the effect is stable, and the operation is easy.
本发明提供了一种医用复合陶瓷材料及其制备方法，所述的医用复合陶瓷材料包括由颈部到切端颜色由深至浅呈梯度变化的至少三层陶瓷层，相邻两层陶瓷层的颜色梯度差值≤10％；所述的陶瓷层包括氧化锆陶瓷粉末、染色剂、光固化树脂、光引发剂和助剂；各层陶瓷层的氧化锆陶瓷粉末和染色剂的总质量按100wt％计，颈部陶瓷层中氧化锆陶瓷粉末占80～90wt％，其余为染色剂；由颈部到切端的各层陶瓷层中所含氧化锆陶瓷粉末按5～10wt％等梯度递增。本发明制备得到的陶瓷材料的颜色呈梯度变化，颜色过渡自然，接近于天然牙齿的色泽分布特征，制备工艺简单，效果稳定，容易操作。
