Abstract In order to improve the performance of ZTA ceramics in oral clinical application, dental braces with ZTA ceramic materials were prepared by gel injection molding, polymer as adhesive, carboxymethyl cellulose as skeleton. We explored the influence of powder solid content, carboxymethyl cellulose (CMC), acrylic acid (AA) and ammonium persulfate (APS) on the bending strength, fracture toughness of ZTA ceramic materials. ZTA ceramics at the optimal process level were prepared and their properties were tested. The results showed as follows: the addition amount of CMC was 0.85 g, the addition amount of APS was 0.8 g, the addition amount of AA was 7.5 mL, the addition amount of Al2O3 was 110 g, and the addition amount of ZrO2 was 33 g. The flexural strength of the ZTA ceramic material was 222.3 MPa, the fracture toughness was 8.67 MPa·m 1/2, the relative density was 0.977, and the shear strength was between 6.06—6.93 MPa, meeting the clinical requirements.
