Formula of high-transmittance zirconia ceramic, preparation method of paste and manufacturing method of dental crown
The invention provides a high-permeability zirconia ceramic dental crown material and a preparation method thereof and a manufacturing method of a high-permeability zirconia dental crown. The high-permeability zirconia ceramic dental crown material is prepared from the following raw materials in parts by weight: 81-90 parts of yttria-stabilized zirconia ceramic powder, wherein the content of yttrium oxide in the yttria-stabilized zirconia ceramic powder is 4 mol%-6 mol%; 10-19 parts of a photosensitive resin premixed liquid; 0.01-0.2 part of a defoaming agent; 0.01-10 parts of a dispersant; 0.01-10 parts of a leveling agent; 0.02-4 parts of a photoinitiator; and 1-10 parts of a rheological additive. The method has the advantages of high raw material utilization rate, low process cost and high surface precision, and the prepared molded dental crown is good in quality, high in strength and good in aesthetic effect.
本发明提供了一种高透氧化锆陶瓷牙冠材料和制备方法以及高透氧化锆牙冠的制作方法，该高透氧化锆陶瓷牙冠材料由以下重量份的原料制成：81‑90份的氧化钇稳定氧化锆陶瓷粉体，所述氧化钇稳定氧化锆陶瓷粉体中的氧化钇含量为4mol％‑6mol％；10‑19份的光敏树脂预混液；0.01‑0.2份的消泡剂；0.01‑10份的分散剂；0.01‑10份的流平剂；0.02‑4份的光引发剂；1‑10份的流变助剂。本发明具有原材料利用率高、工艺成本低、表面精度高的优点，制备的成型牙冠质量好、强度高、美学效果好。
