In this moment there are people that work in dental implants obtained by machining, but with especific zones of implant with material put by means of SLS.

The idea is to improve the oseointegration of the part with the bone.

Hi

If you're not attached to an industry yet, you can see with some collegues of mine, 2 French companies called Dento smile and Biotech based in the south of France (Salon de Provence). They are already printing Co-Cr dental implants and could propose you a colaboration, internship or what not. You can get to their website :

My office is right next to theirs.

Good luck
