What are e.Max crowns? An e.Max crown is an all-ceramic dental restoration that is stronger than stacked porcelain. With e.Max, you can achieve a beautiful and cementable ceramic restoration without an underlying metal coping.
Stomadent Dental Lab creates quality, aesthetically pleasing e.Max dental crowns to help your dental practice succeed.
When to Choose e.Max Crowns
- When you need outstanding aesthetics
- When your patient needs a crown that blends perfectly with the surrounding dentition
e.Max Crowns Material Qualities
- Lithium disilicate
- An all-ceramic material without a metal substructure
- Stronger than stacked porcelain
The dental restorative market started using lithium disilicate ceramics in 1988, before dental labs really started using CAD/CAM technology for fabricating crowns. At that time, a pressure casting technique created the all-ceramic crowns. Fast-forward to 2005 and the process started to incorporate the development of CAD/CAM technology in the dental lab industry. While the same monolithic lithium dioxide was used as e.Max crown material, the technique changed from pressure casting to milling. We’ve used this same technique to create e.Max crowns ever since.
Special Features of e.Max
- e.Max was introduced to the dental restorative market in 1988 using the pressure casting technique.
- e.Max processing was changed to CAD/CAM milling in 2005 to take advantage of technological advances.
- e.Max crowns are very aesthetically pleasing.
- The material used to create the e.Max crown possesses translucent and reflective properties that mimic and blend with neighboring natural teeth.
- e.Max may be fused to a stronger material, such as Zirconia, for added strength or when you need to mask dark areas.

| NOTE: e.Max crowns are not recommended for patients with bruxism or a hard bite. Instead, you’ll want to consider Zirconia crowns for bruxism patients. | |
- e.Max crown preparation is similar to full metal crowns
- Preparation for e.Max is less aggressive than for zirconia or porcelain-fused-to-metal crowns
- e.Max preserves the natural structure of the tooth
How to Take Impressions for e.Max Crowns
There are several different ways to take impressions for e.Max crowns. These are the best ways to do so in order of preference for our dental lab:
Impression-free chairside scans for a total digital workflow
The crown preparation, along with the surrounding hard and soft tissue, is quickly and efficiently scanned at chairside, eliminating the need for traditional impression materials. This digital scan is then seamlessly transferred to the dental lab, offering a precise and mess-free solution that saves time and improves overall workflow.
Hybrid Scanning Method
- Utilizes scannable impression materials and impression trays
- Impressions and bite registration are individually scanned into STL files
- Images are later used to print 3D models in the dental lab
Traditional polyvinyl siloxane impressions and bite registrations
Traditional polyvinyl siloxane (PVS) impressions and bite registrations are effective but can be time-consuming and messy. The process involves mixing, setting, and cleaning, which often makes it less efficient compared to newer methods.
