3D printing high-transmittance ceramic tooth and preparation method thereof
The invention provides a 3D printing high-transmittance ceramic tooth and a preparation method thereof. The preparation method comprises the following steps: preparing a prefabricated ceramic tooth by adopting a 3D printing technology; the prefabricated ceramic tooth obtained in the step (1) is sequentially subjected to rubber discharging, pre-sintering, soaking and sintering, and the ceramic tooth is obtained; a soaking solution adopted for soaking comprises a yttrium source, a first dispersing agent and a stabilizing agent; according to the preparation method, the soaking step is added between pre-sintering and sintering, so that on one hand, the light transmittance of a finished product is improved, and on the other hand, the mechanical property is enhanced; by further controlling the preparation conditions, the light transmittance of the finished ceramic tooth reaches 40-48%, and the relative density reaches 99.5% or above; the preparation method is simple in technological process and beneficial to production and application.
本发明提供了一种3D打印高透光度陶瓷牙及其制备方法，所述制备方法包括以下步骤：采用3D打印技术制备得到预制陶瓷牙；将步骤(1)得到的预制陶瓷牙依次进行排胶、预烧、浸泡以及烧结，得到陶瓷牙；所述浸泡采用的浸泡液的组分包括钇源、第一分散剂和稳定剂；所述制备方法通过在预烧与烧结之间增加了浸泡步骤，一方面提升了成品的透光度，另一方面增强了其力学性能；并通过进一步控制制备条件，使得成品陶瓷牙的透光度达40‑48％，相对密度达99.5％以上；所述制备方法工艺流程简单，有利于生产和应用。
