The all-ceramic e.max crown has many advantages over traditional crowns. Besides its high esthetic qualities, the function and longevity of the crown is excellent as well.

E.max is a system of crown fabrication which allows a porcelain crown to be made without the metal understructure. Traditionally, porcelain crowns are made by bonding the porcelain to a metal support The drawback is that unlike a natural tooth which exhibits a certain degree of translucency, the metal framework under the porcelain blocks out the light. To the keen observer, the difference in shine and translucency between a natural tooth and can be quite obvious. While full porcelain crowns have been done (and are still being done), most have proven to break prematurely. Furthermore, porcelain surfaces are known to wear out opposing natural teeth faster.

The E.max system, unlike its metal based predecessors, has developed a method of making a ceramic crown without metal that is both durable and aesthetic. Since the crown is made entirely out of ceramic, it can have the same translucency as natural teeth.

Simply put, a new all-ceramic e.max crown is esthetically superior to any other type of crown. You just can't get the same finish and natural, living look with a traditional metal core (porcelain fused to metal) crown.

Benefits of a new e.max crown:
  1. you may have discoloured fillings and would like to improve the appearance of the tooth
  2. you may have had a root filling which will need a crown to protect it
  3. it may help hold a bridge or denture firmly in place.
See the difference for yourself!
