Anyone not seeing how C+CSC wasn't proof of concept? Probably lays the ground work for predicates for FDA clearances. What is brazing? what if you wanted a hip stem that was Titanium Sini coated and transferred into porous silicon nitride in the middle? Without brazing I assume you would create the implant out of titanium and coat the porous titanium to achieve this effect.
Zimmers TM dental impant suffered two major issues, lack of fusion and a tendency to grow bacteria. The bacterial issues helped slow fusion rates. The design is very nice in concept however. Love to see a Si3N4 version.
I think the scrutiny Si3N4 has been under is because of the degree of issues that Trabecular Metal had. I also think Sonnys been running Si3N4 through the testing ringer for the same reason. Cant have a TM scenario happen again.
