A restoration of a tooth involves encasing the entire clinical crown with a single piece of cast metal alloy that primarily contains elements considered noble. This restoration type has historically served as a reliable method for rebuilding severely damaged or weakened teeth, offering significant strength and durability. An example would be its use on a molar requiring extensive coverage due to fracture or decay.
The advantages of this approach are considerable, notably its capacity to withstand significant occlusal forces and its resistance to wear and corrosion within the oral environment. Historically, these restorations were favored for their longevity and biocompatibility. The selection of alloys that comprise them is often based on their physical properties, cost, and potential allergic reactions.
