Question: When would you prefer to use Lava Ultimate ( from 3M ) over Emax? if at all..?
Answer: Emax is always my first choice for bondable posterior monolithic all-ceramic restorations. The main reason is over 10 years of clinical evidence of success
Having said that either Lava Ulitmate or Enamic- works best in situations where ideal preparations couldn’t be done— it is easier for cad-cam systems to machine a nondescript margin in a resin containing material
Question: Which system or systems do you feel are the best for electronic shade matching. Are they a substitute or additional aid for a custom shade by the lab. Thank you!

Answer: They are not a substitute for calibrated digital shade taking photography, which is the most important step; i.e. Taking images with at least 2 shade guides in the same plane as the natural tooth — also the images should be shoot in RAW file type. I use the Easyshade as an “adjunct” to my, (1) visual shade analysis, (2) photographic shade analysis (3) Photoshop color analysis, and (4) the Easyshade as a extra piece of the shade puzzle.
