So this time I got a stump shade of lets say somewhere between A3.5 or A4. But my doctor send me a Shade from Ivoclar shade tap IE230 which kind of looks like A3 but with lil bit of orange in it. So basically i think i need to match somewhere around A3.5 So my question is how much does stump shade affecting the Emax crown? I m thinking of using A3 MT thinking that Stump shade has strong A3.5 ~A4 shade that will make my A3MT emax crown look more like A3.5 with stump shade of A3.5~A4 or should i just press A3.5 LT and ignore the stump shade. Not sure how much stump shade is affecting the crowns. Any advices are appreciated!
