This series of pictures from professor Markus Blatz describes my way of working with onlays. This a very common treatment in my clinic. I rsher do onlays than crowns. We always loves the results of our onlays. This is because we are working with self glazed zirconia, SGZ.
The unique transparency of SGZ is giving the feeling and outcomes of a treatment that is fantastic, you almost can’t se the artificial part of the tooth.
Just enjoy it.
