Sensation SL

Sensation SL from Leach & Dillon is my worst enemy right now. I am employed at a lab using this porc. At first I was excited about what I read in the manual. Flourescing, low fusing, great wear. After using it for a couple of months. I feel they have dropped the ball. It is not very stable, which is generally known problem with low fusing porc., It is not terribly esthetic. The opaque is mostly yellow, no matter the shade. With no exception, can it be sent out the door without staing the crap out of it. It’s selection of modifying porcelains are anything but desireable. I would rate it somewhat, kind of, ahead of Ceramco. It is a production porcelain, it is ment to be a rpoduction porcleain, but they don’t chrage production porcelain prices…. 2 thumbs down.

 

D.sign

Ivoclar Vivadent’s crowning achievement, to date, INHO. IPS D.sign is an extraordinary material. It’s synthetically grown, flourapetite crystaline structure is beautiful, when it is layered correctly. That being said, it is one of the most technique sensitive porcelains I have ever used. AND, with that being said, once I learned the conditions that it wanted to be fired in, I was able to replicate that daily, without challenge. It isn’t sold to be a production porcelain, but if you have the right techniques, it could certainly become a VERY good one, very quickly. Some of the things I love about it are; It’s stability under multiple firing schedules, it’s shade matching, out of the bottle (you nearly have no shade adjustment at staining), and mainly it’s abililty to retain the exact surface texture after a natural glaze, and the surface itself! This gets 2 thumbs up from me!
