Well, believe my friend Ed.
I was CDT, son of Dental Professor, brother is Dentist.
Do I know what a custom shade is?? Of course.
I owned a C&B for 13yrs...made enough money to buy One million in CAD/CAM toys.
So, how did that happen if I don't know anything? Been in the field almost 25yrs now.
My employees look at this site everyday. Maybe 200 people on here personally know me, and shake my hand.
Many on this site have been to my facility for training of CAD also!
I do not lie on this forum. Don't care what you think about Zr. Who the heck are you?? Why would I listen to anything you say?
If you are more successful than me at age of 40, then maybe I consider your opinion. Otherwise....ah, ..? You have no place to tell me anything.
Sorry for my blunt statement. You can hire who you want and show me results if you think you can do better! LOL
I have no idea what the heck yopu are talking about Zr in front or back??
Who mentioned Zr anyways?? We are talking about Laboratory grown teeth in Petri dish going into a mouth needing a crown.
