Mike Skramstad Here is a case that I did out of Impulse V1 and e.max LT A1. Crowns on #6,7,8,9,10,11 (V1), crown on 13 and custom abutment and crown on #12 (e.max LT A1)
It was a great case to do and patient was beyond thrilled. It's amazing by getting better proportions and using a more natural porcelain how you can totally transform the smile and patient's esteem. She is beyond thrilled.
However.... as i'm reviewing the case, I noticed that #9 is lower value than #8. The material was the same, porcelain thickness is the same, and stump shades were all the same. The difference is the lack of texture on #9. Light is bouncing off in a different way. I don't know what happened exactly and i'm sure if I shot it with a ring flash it would look better (the reason I use twin flashes...). It's not redo bad... but it's eye opening to make sure you have the texture symmetrical when doing centrals. The laterals are off too... but they were super difficult due to spacing concerns and i'm telling myself that the these little imperfections make a case look more natural 
You also can see the difference in brightness between e.max LT A1 and Impulse V1... highlights the advantage for sure!
