Crowns and Bridges

 

CROWNS

A Dental Crown is a type of dental restoration that completely caps or encircles a tooth or dental implant. They are often used to improve the strength or appearance of the teeth. Crowns are made in the laboratory after an accurate impression of the teeth and then cemented in place by the dentist.


Crowns can be made of several materials like gold, porcelain fused to metal, all-ceramic, and zirconia. They are all very strong materials however the all-ceramic crowns prove to be the most aesthetic of all and are often selected to crown the front teeth. Nowadays latest CAD CAM 3D technology is used in the fabrication of these crowns.

INDICATIONS FOR A CROWN:

  • A large cavity where a tooth needs to be reinforced or strengthened

  • A fractured tooth

  • After a root canal treatment

  • In case a tooth is discolored

  • To close gaps between teeth

  • In case the position of a tooth needs to be changed drastically

BRIDGES

Dental Bridges are a treatment modality for replacing missing teeth in the mouth. They can be made of high-quality porcelain fused to metal (PFM), zirconia, or all-ceramic materials. They help the patients to eat and look better. The teeth on either side of the missing tooth have to be prepared and crowned for this procedure.


Bridges are the treatment of choice in areas where implants are not possible due to insufficient bone or other reasons, in immune-compromised patients, and in patients who do not wish to get a surgical implant procedure done.


Nowadays very aesthetic tooth-coloured all-ceramic bridges can also be fabricated especially for missing front teeth.
