Porcelain Crowns

Porcelain Crowns are used to restore the enamel layer on front and back teeth that are broken or weakened teeth due to oversized fillings or root canal treatments or fractures and can also be used where teeth are are worn, discoloured, rotated, poorly shaped, cracked. Porcelain Crowns can be used to correct discolouration, worn teeth, broken teeth, a large cavity, spaced teeth, and crowded teeth.

Firstly, when a Porcelain Crown is made, the tooth is prepared to allow for a thin spacing where the Porcelain is to fit around the tooth. A precise impression is made and the Porcelain Crown is constructed. When the crown has been made by our dental laboratory, the crown is then brought back to the mouth and bonded into position, covering the tooth to slightly below the gums, replacing the missing enamel.

When joining Crowns together, you are able to bridge gaps in between teeth where teeth are missing.  this is known as a bridge.

Porcelain Crowns to rebuild and strengthen weak teeth

A Porcelain Crown is a strong cover that entirely lies over the top of a tooth, restoring broken down teeth to their ideal anatomical shape and colour, while protecting the remaining tooth structure underneath.

 

Porcelain Crowns are indicated to strengthen broken down teeth and prevent teeth from breaking; crowns are now used in many different circumstances for many different reasons.

 

Traditionally Dental Crowns or Caps have been known for their poor ability to mimic the colour and appearance of a natural tooth. With recent advances in the way Crowns are constructed at Brisbane Smiles™ we are choosing to use E.max Porcelain Crowns and Zirconia Porcelain Crowns because of their superior cosmetic appearance than traditional Porcelain-Fused-To-Metal Crowns.

Porcelain Crown Technology

 

The milling of the inside of a E.max or Zirconia Crown is performed by a CAD-CAM Computer system in our own onsite World Class Laboratory. This provides our Technicians with high strength inside of the crown whilst maintaining extremely high aesthetic properties and an optimal fit, even better than traditional Porcelain-Fused-To-Metal Crowns. Zirconia is a white material, where metal is a grey material, thus zirconia is an ideal tooth colour substitute. This distinct cosmetic benefit also arises because light can transmit through the coping in a way that perfectly mimics a natural tooth.

A layered Porcelain is layered over the computer milled coping, in a way that personalises the colour and texture to match adjacent teeth.

E.max, Zirconia and Porcelain technology means that Smile Artistry™ can provide a unique combination of both strength and beauty, that is not widely utilised in the Dental Profession as yet.

We do not often use metals, but if we do, then these are the compositions:
Porcelain Fused to Metal: Gold Alloy contains: Au 51.5%, Pd 38.5%, In 8.5%, Ga 1.5%, Re <1.0%
