HOW DO BRIDGES WORK?:
Bridges are required when more or more teeth are missing. Gaps left by missing teeth eventually cause the remaining teeth to rotate or shift into empty spaces resulting in bad bite, gum diseases or temporo-mandibular joint disorders. Bridges are commonly used to replace one or more missing teeth. Brides are cemented to the natural teeth surrounding the missing space.
Before fabrication of crown or a bridge, the teeth supporting it must be reduced in size so as to receive the crown or bridge over it with proper fit.
We at our clinic help you decide the choice of material used for the fabrication of crown or bridge which depends upon location of missing tooth in mouth, function, aesthetics and cost.
TYPES OF CROWNS & bridges
Metal Crowns: :
Used only in back teeth. Very rarely used now a days.
Porcelain fused to metal crowns:
Most commonly used material. Consists of metal as a base over which porcelain is put in layered fashion. Superior strength due to metal and aesthetics due to porcelain which is matched with the patient's natural adjacent teeth. Black line at the edge of the gums sometimes makes them in appropriate in front teeth
Zirconia or metal free crowns:
superior strength and aesthetics. Zirconia is biocompatible material and provides best visually appealing crowns which blends well with your natural teeth.
Crowns and Bridges last for good 8 to 10 years if supporting teeth are healthy. The life span of bridges can be more provided they are maintained properly with good oral hygiene.
