So we have a doctor that attended a symposium and is asking us about our zirconia (we use Origin Beyond Plus). He's now insisting that only use zirconia with a Y3 classification, as opposed to Y5 or Y7. I don't know what these classifications are (I do know they're different than ISO classes). I read through the literature that he was provided (I'll link below),but the only information it really offered is that doctors should only used Y3 zirconia, and they repeatedly name BruxZir (I will go ahead and assume Glidewell is a sponsor). Does anyone know what this Y-rating is, whether or not it's important, and how to handle this situation? TIA.
