Embodiment Construction
[0026] Its preparation method comprises the following steps:
[0027] Step 1: Preparation of root material titanium alloy composite powder. The sintering ratio is 98%Ti+1.5%Zn+1.0%Mg+0.5%Ag (mass fraction) with an average particle size of 21.2μm Ti, 30μm Zn, 55-100μm Mg, Ag mixed nano powder in drying Dry in the box at 150°C for 11 hours, mechanically mix the above powder in a QM-3SP4J planetary ball mill for 24 hours, mix the powder evenly and dry it at 80°C for 1 hour to obtain metal powder;
[0028] Step 2: 3D printing model construction. The data obtained by scanning the scanned area with MIMICS software were separated and reconstructed to obtain a three-dimensional model of the tooth root and abutment area to be extracted. Use Magic software to digitally design the 3D model and adjust the printing parameters as the implant model to be printed;
[0029] Step 3: Laser 3D printing molding. Copy the data of the printed implant model to the 3D printer for printing, set the...
