Full Cast

Description

A tried-and-true dental restoration, full cast crowns have over a century’s worth of proven durability and longevity. Our high-quality full cast restorations can last a lifetime with proper maintenance. They are fabricated out of noble and high noble alloys, which allows them to provide strength, extreme durability, biocompatibility, and gentleness on opposing dentition. They are ideal options for the posterior region where there is minimal room outside of the esthetic zone.
