Dental bridge

Dental bridge, as the name suggests, bridges the gap caused by one or more missing teeth and improves the face aesthetic. A dental bridge comprised of two crowns; that would be placed over the teeth on either side of the gap, and a false tooth/teeth between those. The two crowns are called abutment and the false teeth called pontics. Dental bridges also can be supported by dental implants.When once loses a tooth/teeth, the risk of high risk of bone loss, unless the tooth/teeth are replace by dental implants or cosmetic crowns. It is crucial to address the issue of missing teeth as soon as possible as the loose of bone density will lead to shrunken and drawn appearance which is undesirable.Different material used for the construction of bridges; however the main two types are:

  • All-ceramic bridges
  • Metal ceramic bridges

All-ceramic crowns

For long the metal fused bridges have been the standard choices of bridges. Thanks to the advance of technology ceramic bridges are becoming the great alternative. Best example of ceramic bridges is Zirconia bridge. Zirconia bridge is rapidly becoming the preferred choice of all-ceramic crowns. They are strong and long lasting, withstand wear and tear in compare with other types of bridges. They resemble the colour of your natural teeth; therefore no one would know you are wearing a bridge.  Zirconia has medical applications like artificial joints. A zirconia bridge is biocompatible, which means people are least likely to develop an allergic reaction to this material and thus considered a preferred choice of material over porcelain fused to metal crowns.

Metal ceramic bridges

Metal ceramic bridges are also called porcelain fused/bond to metal bridges are the most conventional bridges used. This metal bonded bridge is made of a metal frame and ceramic crowns which are to replace the missing teeth. Metal ceramic bridges are durable and very strong; the risk of breakage and chipping is very minimal. However there are least favoured when it comes to appearance and aesthetic of them as the grey line can be seen around the gum which is not desirable. The disadvantages of metal ceramic bridges has given way to popularity of all-ceramic as there is not metal rejection and appearance wise they resemble the colour of your own natural teeth.
