Abstract
The present disclosure relates to the manufacture of silicon nitride implants with increased surface roughness and porosity.
Claims16
A method for manufacturing a silicon nitride implant, the method comprising:
- providing a silicon nitride green body;
- increasing the surface roughness of the silicon nitride green body;
- increasing the porosity of the silicon nitride green body;
- and
- sintering the silicon nitride green body to obtain the silicon nitride implant.

A method for manufacturing a silicon nitride implant, the method comprising:
- providing a silicon nitride green body;
- laser etching an outer surface of the silicon nitride green body to increase the surface roughness of the silicon nitride green body;
- peck drilling and/or laser etching the silicon nitride green body to create porosity in the silicon nitride green body;
- and
- sintering the silicon nitride green body to obtain the silicon nitride implant.
