IPS Empress® Overview
IPS Empress® Esthetic Crown
There’s simply no other all-ceramic option that provides the breathtaking esthetics of IPS Empress®. Its leucite glass ceramic is suitable for single-unit crowns, inlays and onlays in the cosmetic zone. The high translucency of Empress doesn’t merely provide lifelike esthetics, but picks up shading from surrounding dentition to provide the optimum shade match even in difficult cases. Its average flexural strength of 160 MPa is roughly 60 percent higher than that of conventional porcelain, making it the durable, esthetic choice.

Clinical notes from Dr. Hornbrook:
Our next category is IPS Empress ... Our next category is IPS Empress and although we don’t do as much of this as we did in the past because E-Max has taken a lot of this market share, as well as our KDZ Bruxer® Aesthetic, we still use it in some applications. This is a ceramic that is leucite-reinforced. Flexural strength, approximately 200. If we look at the flexural strength, our monolithic Brux or KDZ Bruxer 1000 to 1200, our KDZ Bruxer® Aesthetic 650, E-Max 400, Empress 200. The porcelain we stick on our PFM 100.
Where do I use this? I use it for veneers and anterior crowns, especially when my patient wants a very bright shade and they have redness in their complexion. The reason I chose Empress is that E-Max, even though it’s twice as strong, tends to, and a lot of clinicians watching this can totally relate to this and every [inaudible 00:16:33] can relate to this, E-Max tends to look gray. Even though it looks like a B1, or a bright B1 outside the mouth, you take it to the mouth, someone with redness in their complexion, it will look like a very, very bright C1. Be careful with that.
The other time that I’ll use Empress instead of E-Max is if I have a grayish prep. Grayish means if the prep is in the D or C ranges versus the A and B ranges for the VITA shades, I use Empress because E-Max tend to gray out.
