Bob Conte Not the most complex case, but I wanted to see how the HT block compared to other high translucency materials. Celtra mills out fine enough to be a decent option for inlays and onlays. My go-to has always been the hybrid materials for these restorations, but it feels a bit naughty to call Lava Ultimate or Cerasmart a ceramic. I know the FDA/ADA is fine with it. With Celtra we can call this a ceramic onlay and with it's polish only option it is just as efficient as the hybrid materials. In this case I did fire it for 10:30 in order to be able to add stain in the wrong orientation.
