A 3Y-TZP zirconia material whose surface is modified by plasma treatment.
An implant made of a 3Y-TZP zirconia material whose surface is modified by plasma treatment.
A method for modifying the surface of a 3Y-TZP zirconia material, comprising the steps of:
- (a) filling a carrier gas into a plasma generating device;
- (b) generating plasma in the plasma generating device;
- and
- (c) irradiating the generated plasma onto zirconia.
A method for manufacturing a dental implant whose surface is modified, comprising the steps of:
- (a) preparing an implant composed of a 3Y-TZP zirconia material;
- (b) filling a plasma generating device with a carrier gas;
- (c) generating plasma in the plasma generating device;
- and
- (d) irradiating the generated plasma to the implant of step (a).
