It was determined in a laboratory ! There are no real world cases.
As I mentioned before , Titanium implants have a 99% long term success rate. Sintx's Si3N4 has a non proprietory patent, which means anyone can make it.
Sintx can't have a solution to a non existent problem that can only be seen in a laboratory or university re search paper.
If Dick Van Dyke was hired by SinTx Technologies as their spokesperson for Si3N4 and was able to lobby the government on there behalf do you think this would help the stock ?
