whatever doctor prescribed you that shade has got a relic shade guide. that thing has been discontinued for 15+ years. it was an old denture tooth shade guide. i went and did some homework for you and unfortunately, there is nothing that matches it well, not the 3D guide, not the classic vita, bioform or chromoscop. you defintely have to get your hands on the actual 4D tab (if you dont have it already) probably start with your A4 porcelain and then have to do alot of external staining. i am holding the 4D tab right now next to a A4 (A4 is as close as you can get it on the vita guide and its not close) and the 4D defintely has more dark brown/burnt orange in it. wish i could help you more but hopefully got you pointed in the right direction and gave you advice to start with.
