The invention discloses a zirconium oxide implant material and a preparation method thereof, the zirconium oxide implant material comprises an implant part and a zirconium oxide abutment, and the preparation method of the zirconium oxide abutment comprises the following steps: (1) drawing design: selecting an implant and a matched metal abutment, surveying and mapping a hexagonal connecting part of the abutment and the implant by using a laser three-dimensional measuring instrument, and drawing an abutment drawing; in the preparation process of the zirconium oxide abutment, a secondary sintering method is adopted, a formed green body is primarily sintered to obtain a loose and porous zirconium oxide ceramic block, then the ceramic block is ground according to the amplified size of the zirconium oxide abutment to obtain an initial shape of the abutment, and then the initial shape of the abutment is sintered to the final sintering temperature to enable the material to be completely compact to obtain the zirconium oxide abutment. After secondary sintering, the grain boundary strength of the zirconia ceramic is reduced, the mechanical property is reduced, but all properties of the material can still meet clinical requirements, and meanwhile, the repair cost of dental implant is reduced.
本申请公开了一种氧化锆种植体材料及其制备方法，其包括种植体部和氧化锆基台，所述氧化锆基台制备包括以下步骤：(1)图纸设计：选择种植体和配套金属基台，用激光三维测量仪对基台和种植体的六角连接部分进行测绘，绘制基台图纸；本申请在氧化锆基台的制备过程中采用二次烧结法，将成型后的生坯经初步烧结后得到疏松多孔的氧化锆瓷块，然后对瓷块按照氧化锆基台放大后的尺寸进行磨削得到基台的初形，再烧结到终烧温度使材料完全致密得到氧化锆基台，二次烧结后氧化锆陶瓷的晶界强度下降，机械性能降低，但材料的各项性能仍能满足临床要求，同时降低了牙种植的修复成本。
