Keep in mind the Glidewell one is done only through Glidewell they do not sell the Ti base separately, you design they mill and assemble ZR. Same as the Keystone prima conex.
not true. I buy their bases all the time. Their tie abutments library is locked but not the hybrid. As long as you buy their scan flags they will give u the library free. Unless somthn changed in the last 2 years.
