Crowns & Bridges
A Prosthodontist is a specialist dentist that deals with the replacement of missing teeth and the associated soft and hard tissues by prostheses (crowns, bridges and dentures) which maybe fixed or removable, or maybe supported and retained by either teeth of Dental Implants.
What are dental crowns?
A crown protects and strengthens a heavily filled tooth from fracture by preserving the remaining tooth structure. Unlike veneers, porcelain crowns cover all surfaces of the tooth; they are mostly used when the tooth is damaged, fractured or very broken down. Another advantage is to improve the appearance of a tooth.
Dental porcelain can be sculpted to closely replicate the look and shape of natural tooth enamel, while providing good strength.There are three basic types of dental crowns – porcelain, porcelain bonded to metal, and porcelain/Zirconium. They are created to feel and look like natural teeth.
Why I might need a crown:
If you have a large cavity and not enough tooth structure left.
If a large portion of your tooth is fractured.
If you have root canal treatment.
To restore a dental implant used to repalce a single missing tooth.
With good oral hygiene and maintenance, crowns can provide an excellent long-term solution.
What are dental bridges?
Bridges are a good option for replacing one or more missing teeth. A bridge is fixed to the remaining natural teeth either side of the gap, restoring the look and function of the missing teeth. Like crowns, they are now available as an all-ceramic option for superior appearance.
Dental bridges generally require the reduction of neighbouring teeth to make room for materials used to create the bridge. Alternatively dental implants can support a bridge.
There are several different kinds of bridges.
Conventional bridges: A secure, long-lasting option. The bridge is anchored on neighbouring teeth and cannot be removed by the patient.
Resin bonded bridges or Maryland bridges: Most suitable for a single missing tooth. This is essentially a sticky bridge which is bonded to the natural teeth and requires minimal tooth preparation.
Implant-supported bridges: These bridges can be fixed to existing dental implants by being screwed or cemented in place. Once fitted, the implants provide the foundation for long-term support of bridges or dentures.
