My favorite thing to do is match a single tooth into a difficult situation. Here is one today that I did.
Tooth #7 had RCT, metal post, and composite buildup that fractured off.
I built the tooth up using the existing metal post and remaining tooth structure and made a full coverage crown.
Vita Trilux 3M2 (the easy shade 3M1). I don't have that shade in trilux, so I had to increase the chroma with Lustre Pastes. Used a combination of L-A, L-N, L-2, L-3, and L-5 Lustre Pastes in 2 fires to get this final result. Bonded with Variolink Veneer (old formulation) (-1).
This will be my topic at CEREC 30 breakout Saturday morning and I videotaped the contouring and LustrePastes technique on this case.
