Howdy everyone, so I have been a dental tech for about 12 years, and am quickly realizing that I don't know as much as I thought I did. The lab I work for has a large amount of zirconia flowing through it, and over the last few years we've had a lot of bridges fracture, and as the main digital guy I fear that a lot of the failures may be my fault. We were using Ceramill Zolid FX for several years before moving over to the Katana STML, and we are now moving into the Katana YML. So (and feel free to speak to me as a child) what are all of your minimum guidelines for doing zirconia? Minimum Thickness, Occlusal room, bridge span (pontics, anterior posterior),connector sizes, etc. I've been under the impression that we have had failures because we have not been playing by the rules as far as contraindications go, but I also think I missed a step going from what zirconia used to be to what it is now, as have our doctors who seem to check every contraindication box when prepping for zirconia. Any information and advice would be greatly appreciated!
