Ivoclar Vivadent has continued to expand shades, translucencies, and indications for the market leading IPS e.max® CAD. This expansion has created great opportunities to utilize CAD/CAM machines for more clinical indications. Unfortunately, having more options can sometimes lead to confusion, specifically which program to select to process my IPS e.max CAD restoration. Variables such as number of restorations, size, translucency, type of glaze are factors that can affect the appearance and physical properties of the final restoration. [Read more…]
Over the last several years a trend of resin based materials for CAD/CAM systems has emerged.
- Fast milling
- Smooth margins
- No firing required (not capable of being fired)
- Intraoral composite adjustments
- Low strength compared to high strength ceramics available like IPS e.max® CAD
- Low modulus of elasticity
IPS Empress® CAD
Beautiful Esthetics, Maximum Efficiency, Clinically Proven
For over 20 years, IPS Empress has led the Esthetic Revolution offering clinicians the ability to provide beautiful all-ceramic restorations for their patients.
Over 20 years and 30 million restorations make IPS Empress one of the most clinically successful all-ceramic materials in dentistry.

One of the great things about IPS e.max® CAD is the variety of translucencies that are available to us as clinicians. This allows us to use the material in a number of clinical situations. My general rule is that if there is a lot of good looking tooth structure to work with then using the high translucency block is the best option. It allows me to be much more conservative with my preparation.
The following case study shows how the use of a high translucent IPS e.max CAD block can be used to blend into the existing tooth structure. The patient has mesial caries present on #30 and an existing distal occlusal amalgam. (Figure 1 and 2) [Read more…]
Since the late 1950’s porcelain fused to metal (PFM) has been the gold standard for full coverage crowns because of its strength and longevity. Over time however, tissue surrounding a PFM restoration recesses and margins are exposed, which is not esthetically pleasing. Therefore, the demand for all-ceramic restorations has increased.
Today a dentist can use IPS e.max® CAD with confidence knowing they are placing a durable, highly esthetic material that has proven clinical success and can be used for most indications. An in-vitro fatigue test study by New York University concludes IPS e.max CAD crowns are comparable to the gold standard, i.e. Metal ceramics. [Read more…]
