[0031] The invention provides a ZrO 2 A method for preparing a base all-ceramic implant, comprising the following steps:
[0032] Soluble zirconium salt, strong alkali and solution containing doping elements are prepared by nano-powder preparation technology to obtain nano-ZrO with stable doping elements 2 Powder;
[0033] The nano ZrO 2 The powder is mixed with the photosensitive resin to obtain a ceramic-photosensitive resin prefabricated slurry;
[0034] The ceramic-photosensitive resin prefabricated slurry is printed by additive manufacturing technology according to the simulated tooth model to obtain ZrO 2 ceramic green body;
[0035] The ZrO 2 Ceramic green body debinding and sintering to obtain ZrO 2 Ceramic substrate;
[0036] The ZrO 2 The ceramic matrix is subjected to ion infiltration, sintering and mineralization treatment to obtain ZrO 2 All-ceramic dental implants.
[0037] The present invention makes the prepared ZrO by adopting additive manufacturin...
