Porcelain crowns have long been the cosmetic dentist’s best friend. They provide a long lasting, beautiful restoration that is very esthetic. The cosmetic enhancement uses of porcelain crowns include, changing color of teeth, closing gaps between teeth, fixing teeth that are crooked or crowded, changing shape or size of teeth. Porcelain crowns are also used to cover and protect damaged teeth, (tooth that had root canal treatment, broken, cracked, large fillings), and to act as a new tooth in the case of dental implants.
Full porcelain crowns, unlike porcelain fused to metal crowns, has translucency. The porcelain’s translucency allows it to reflect light much like natural teeth. There are many different types of porcelain utilized in many different ways, however, the limiting factor has always been strength against fracture. E.max porcelain crowns have combined optimum translucency and strength.
What are E.max Porcelain Crowns?
E.max porcelain crowns are a highly esthetic crown originally developed to be used on implants. Dental implant porcelain crowns require greater strength against fracture than crowns on natural teeth. E.max porcelain crowns (due to superior strength) can also be made thinner than other porcelain crowns, allowing for more natural translucency and beauty. E.max porcelain crowns are made from a single block of lithium disilicate ceramic. This type of porcelain is considered a very high grade material which has been harvested for its toughness, durability and opaque qualities which make for a highly prized crown.
E.max porcelain crowns are considered to be a perfect match against the backdrop of your natural teeth. The transparent color, lifelike shape, along with its light reflection properties create the ideal restoration. There is no metal framework on e.max porcelain crowns which means there is never a chance of a grey line of metal showing through your gums. They are strong, long lasting and unlikely to crack or fracture as compared to many other types of crowns. They are considered to be at less risk of chipping compared to zirconia porcelain crowns.
The beauty of this technology is that e.max is not limited only to porcelain crowns. The same techniques and materials are available for porcelain veneers, porcelain inlays, porcelain onlays, and porcelain crowns over dental implants.
E.max lithium disilicate glass ceramic delivers the fit, form, function, and esthetics demanded by modern cosmetic dentistry but with the enhanced strength and light reflecting properties dentists demand as well. Since the e.max porcelain crown system was introduced almost 40 million restorations have been and they have been proven effective for use.
Any Disadvantages of e.max porcelain crowns?
-The main disadvantage of e.max porcelain crowns is with the cost. The lab equipment and highly specialized lab training to make this crown are the reasons why the quality comes with a higher price tag.
-The second disadvantage with e.max porcelain crowns is that it can not be used to make a porcelain bridge, and fusing of more than 2 teeth is not recommended.
-The third main disadvantage is, as with most porcelain crowns, there tends to be a higher chance of sensitivity after the crown is cemented in place. The sensitivity may last days or weeks.
