Metal – Free Porcelain Crowns

by uniadmin | April 28, 2017

All-porcelain (ceramic) crowns without metal core are distinguished by their excellent aesthetics. Light is not only reflected, there is also real transparency as seen in natural teeth. This effect makes the all-porcelain crown perfect for use in anterior areas, whereby minor form and alignment corrections are also possible.

The indication for a crown is when a tooth is damaged extensively and reconstruction with a filling, an inlay, or a veneer is no longer possible. This is the case when:

  • The defect is subgingival
  • The tooth has been root-canal-treated (devitalized)
  • The tooth is broken off (fractured) in a deep lying area
  • Caries or old fillings are widespread throughout the tooth

All-porcelain (ceramic) crowns without metal core are distinguished by their excellent aesthetics. Light is not only reflected, there is also real transparency as seen in natural teeth. This effect makes the all-porcelain crown perfect for use in anterior areas, whereby minor form and alignment corrections are also possible.

A further advantage of the metal-free ceramic crown is the tooth-shaded margin, which need not be placed under the gum line. Thus, the crown margin does not irritate the gingival tissue and prevents gum recession.

Porcelain (ceramic) is an extremely biocompatible material with no allergenic potential. This can be a real advantage to predisposed (allergic) patients.

With smaller defects, limited to the outer surface, we prefer treatment using porcelain facings (veneers), allowing more of the natural tooth to be preserved during preparation.

Progressive development in ceramics brings forth ever stronger materials, such as zirconium ceramic. Therefore, it is now possible to fit metal-free porcelain crowns in the posterior area.

Cergogold restorations not only look like natural teeth, but they also perform like them! The Cergogold system exhibits smooth surfaces and hardness values resembling those of natural teeth. This type of surface has been proven to abrade the antagonists at a natural rate. As with the Golden Gate alloy range, Cergogold can also be veneered with Duceragold porcelain. Matching the shades of all-ceramic and metal-ceramic restorations in the same patient’s mouth is no longer a problem.

  • 20% softer than competing systems
  • Fracture and shear resistance better than any other pressable ceramic
  • The highest performing low wear restoration when overlaid with hydrothermal porcelain
  • Light Dynamic results, no adverse effects under various lighting conditions!
