Embodiment 1
[0056] A safe dental implant method uses nano-zirconia composite ceramic teeth.
[0057] The preparation method of the nano-zirconia composite ceramic tooth comprises the following steps:
[0058] S1. Take 140g of zirconia, 20g of alumina, and 1g of yttrium oxide and add them to 160g of dispersion liquid and stir for 20min at a speed of 500r / min, and adjust the pH to 10 with 25wt% ammonia water to obtain a mixture; mix the mixture and zirconia balls by mass Put it into a ball mill with a ratio of 1:3, and ball mill it at a speed of 150r / min for 12 hours to obtain a slurry;
[0059] S2, aging the slurry for 24 hours to remove air bubbles in the suspension;
[0060] S3. Inject the aged slurry into a gypsum mold, put the gypsum mold into a centrifuge, centrifuge at a speed of 1000r / min for 200min, take it out, demould, and obtain a green body;
[0061] S4, drying the green body at a temperature of 30° C. for 35 hours to obtain a green body;
[0062] S5. The cutting machine is ...
