I HAVE called them. I did that over a year ago. They will not recommend dentists. They don't sell directly to dentists anyway. They sell to labs. The ivoclar rep did recommend I get crowns identical to the ivoclar I have. That's what I was trying to do - but that dentist ruined them. I've called the lab that made them but have stopped answering my e-mails. They wouildn't even talk to my allergist. When he called for me they told him their computer system was down. That cost me $150 right there - to the allergist. I really want to know EXACTLY how these good crowns were made - including the type of glaze used. But they won't tell me.
