E-MAx Crowns:


The E-Max crown is a type of all-ceramic dental crown which is preferred for its translucency, longer lasting, aesthetic qualities. This crown is often used for a highly attractive appearance which ensures that they compliment the rest of your teeth.



E-max is a type of all-ceramic crown which has one of the best translucent properties, while still providing extra strength and durability compared to other all ceramic restorations (flexural strength of 360-400 MPa). This crown is made from lithium disilicate ceramic and can be pressed or milled.


  • High strength (400 MPa) and high esthetics
  • Minimally invasive, accurately fitting restorations
  • Four levels of translucency and additional Impulse ingots for maximum flexibility
  • Lifelike esthetics, irrespective of the shade of the preparation
  • Adhesive, self-adhesive or conventional cementation depending on the indication


  • (Thin) veneers
  • Minimally invasive inlays/onlays (1 mm)
  • Partial crowns and crowns
  • Bridges in the anterior and premolar region


Full Zirconia Crowns (Bruxir and Bruxir Esthetic)

BruxZir® Solid Zirconia is a full monolithic zirconia crown, with NO porcelain overlay. It is by far the strongest esthetic crown designed for demanding situations like bruxism, implant restorations and areas with limited occlusal space. (870 MPa)

Designed and milled using CAD/CAM technology, BruxZir Solid Zirconia is sintered for 2.0 hours at 1,530 degrees Celsius to achieve optimum strength. The final BruxZir crown or bridge is then glazed to a smooth surface.

Disadvantage is that this material is not as translucent as other materials. In response, Bruxir Esthetic was introduced to address the esthetic concerns in the anterior zones, with 650Mpa.


Lava (PFZ) Crowns

lava  Traditionally, Porcelain Fused to Metal (PFM) crowns were developed by porcelain fusing to a metal substructure.  With further development, all-ceramic (porcelain) dental crowns were developed to produce a more natural appearance.  Significant advancements have since been made, with Lava dental crowns being preferred over PFMs by most dentists.

  Lava dental crowns present an innovative computer-aided design/computer-aided manufacturing (CAD/CAM) technology to produce an all-ceramic crown on a zirconia base.  Lava dental crowns were created by the need for all-ceramic dental restorations in the posterior region, which is an increasingly important aspect of dental care.  Until Lava dental crowns, there were no real suitable ceramics or economic processing procedures available. 

 The Lava system is based on the machining of presintered zirconia, which, due to its outstanding mechanical properties, its biocompatibility, and its excellent esthetics in combination with a specially designed veneer ceramic, is the ideal candidate for these applications. Zirconia is a high-tech ceramic material that is characterized by its outstanding stability and biocompatibility, as well as strength levels that are significantly higher than other all-ceramic materials.  In addition to strength, Lava all-ceramic system restorations display excellent esthetics and precise fit characteristics.  In combination with a corresponding CAD/CAM unit, the use of an easy-to-machine presintered ceramic material allows for the first time a reliable, fully-automated and thus, fast manufacturing of the Lava Dental Crown. 

The advantages of Lava Dental Crown is summarized:

  • Excellent CUSTOMIZABLE esthetics and translucency
  • Outstanding marginal fit
  • 8 shades of zirconia framework
  • Ideal for 3-unit bridge applications

 The esthetics and biocompatibility of Lava restorations represent the optimum in all-ceramic systems with excellent clinical margin, strength, fit, and superior aesthetics.  Preparations require removal of less tooth structure, and cementation can be accomplished using proven, conventional techniques.

If you want a natural and lasting change to your smile while optimizing length, rotations and alignment problems, then Lava crowns can reshape and whiten your teeth and improve your smile dramatically. 



Remember, your smile speaks before you even say a word!
