The invention discloses a preparation method of a high-uniformity zirconium oxide porcelain block for an all-ceramic false tooth. The preparation method comprises the following steps: by using spherical powder particles as a raw material, injecting powder composed of a zirconia base material and an additive acrylic resin into a mold cavity, carrying out dry pressing to obtain a dry-pressed green body, and carrying out warm pressing in a warm isostatic press cavity, and then carrying out oscillation cold pressing to obtain the high-uniformity zirconium oxide porcelain block for the all-ceramicfalse tooth. In addition, the invention further discloses a product obtained through the preparation method of the high-uniformity zirconium oxide porcelain block for the all-ceramic false tooth. Theproduct has the advantages of high uniformity, stable strength and fewer processing defects, and is beneficial to promoting the development and application of zirconium oxide in the field of dental restoration.
本发明公开了一种高均匀性全瓷义齿用氧化锆瓷块的制备方法，以球形粉体颗粒为原料，所述粉体由氧化锆基料和外加物丙烯酸树脂组成，首先注入模具腔体进行干压，得到干压坯体后，放入温等静压机腔体中进行温压，然后再进行震荡冷压，即得到高均匀性全瓷义齿用氧化锆瓷块。此外还公开了利用上述高均匀性全瓷义齿用氧化锆瓷块的制备方法得到的制品。本发明所得制品均匀性高、强度稳定、加工缺陷少，有利于促进氧化锆在口腔修复领域的发展和应用。
