The HT ingots cannot be used for most full coverage restorations. These ingots are so translucent that when used in larger full coverage situations, we run into low value problems - exactly as was discussed on the first post in this thread. HT shines with the thin or no-prep veneers, inlays, onlays and SMALL full coverage restorations (anywhere this ingot can grab/absorb color). Also, the HT is very sensitive to underlying tooth color. The LT ingot is still the best choice for full coverage stuff because of it's value compared to the HT. I always wanted crowns that had great "translucency", glassy incisal edges, but over the years I learned that proper value is most important to me. The HT are a great addition to the e.max portfolio definetely, but LT is still the "workhorse" and the "go-to" ingot. Also, matching the 3D shade tabs is tough, no question. Making ingots that match those tabs closely would be next to impossible.
