Crown and Bridges
Dental Crowns and Bridges
Crowns and bridges are fixed restorations designed to rebuild the strength of teeth that are too damaged for simple fillings. A crown functions as a "cap" that completely encases a compromised tooth, while a bridge replaces one or more missing teeth by anchoring the healthy teeth on either side.
Material Science in Modern Prosthetics
The durability of these restorations depends heavily on the material used:
Zirconia
Known for extreme strength. It is ideal for molars to handle heavy chewing forces.
E-Max (Lithium Disilicate)
Offers superior translucency, mimicking natural enamel for front teeth.
Porcelain-Fused-to-Metal (PFM)
A classic choice combining the strength of a metal substructure with a tooth-colored exterior.
Precision Fitting and Longevity
The success of a crown or bridge lies in the "marginal fit". It is the seal where the prosthetic meets the gum line. If this fit is not precise, bacteria can seep underneath, causing new decay. Advanced digital impressions ensure a micro-millimeter fit, preventing leakage and ensuring the gums remain healthy. With proper maintenance, these restorations can protect a tooth for decades.
