My Question: Im redoing 8&9. Originally they were done in '09 with e.max. The shade originally was an A-1;pressed in LT with a thin enamel overlay on the incisal 1/3. The stump is ND-4. The old crowns have darkened alot. They are a value similar to a dead C-range. They also have a blackish residue inside. The Doctor said he didnt use any cord on the seat appt., and used RelyX.
Im wondering what could have caused the darkening and the 'black mold' looking stuff, and my second question is I have over 1mm labial room..do you think I could be safe using a V-1 ingot? I think its a better match than the LT A-1 for a core. 1mm on a ND-4?
