These are the fixed prosthetic devices (unlike the removable prosthetic device: Dentures) which are cemented by the dentist.
Crown also called cap is used to entirely cover a damaged tooth. Besides strengthening a damaged tooth, a crown can be used to improve its appearance, shape or alignment of the tooth. A crown can also be placed on top of an implant to provide a tooth-like shape and structure for function. Porcelain or ceramic crowns can be matched to the color of your natural teeth. Other materials include gold and metal alloys, acrylic and ceramic. These alloys are generally stronger than porcelain and may be recommended for back teeth. Porcelain bonded to a metal shell is often used because it is both strong and attractive.
We recommend a crown to
- Replace a large filling when there isn’t enough tooth remaining
- Protect a weak tooth from fracturing
- Restore a fractured tooth
- Attach a bridge
- Cover a dental implant
- Cover a discolored or poorly shaped tooth
- Cover a tooth that has had root canal treatment
A bridge may be recommended if you’re missing one or more teeth. Gaps left by missing teeth eventually cause the remaining teeth to rotate or shift into the empty spaces, resulting in a bad bite. The imbalance caused by missing teeth can also lead to gum disease and temporomandibular joint (TMJ) disorders.
Dental Bridges are the gold standard to replace missing teeth (the Pontics). It is a fixed prosthesis as opposed to removable prosthesis and it is used to replace one or more missing teeth. Bridges can be placed on two natural teeth (the abutments), or it can be placed on dental implants, in some cases combination of natural teeth and implant can also be used.
Whenever a tooth is lost, it is best to restore the missing tooth as soon as possible within one month of healing. If the time elapsed is longer, the teeth next to the missing teeth will shift and the opposing tooth can extrude to fill in the empty space. This domino effect causes interference on your bite, and due to shift on the axial inclination of teeth, gum or periodontal disease can start, however none of these conditions reveal any discomfort to the patient, until it is in the advanced stage.. Usually after extraction of teeth, It is highly advisable to even have a temporary bridge placed as soon as possible, within one or two weeks to stop shifting of teeth, and prevent bite damage.
They require preparation on the anchoring teeth and covers fully the anchor teeth to hold the missing teeth and could be made with porcelain fused to metal or gold, with all porcelain or Ceramics.
They are much more conservative than conventional bridges, very little tooth structure is removed from the anchoring teeth, they conserve tooth structure, no sensitivity or discomfort.
These types of bridges are used when there is no tooth adjacent to the missing tooth or teeth is present.
Inlay Onlay Bridges
If adjacent teeth have large fillings, and patient does not want much tooth structure to be removed, this is the choice.
