What type of crown replaces the entire crown area of a tooth?

Jacket crown
Full crown
Onlay
Dowel crown

The correct answer is: Full crown

A full crown is designed to cover or replace the entire anatomical crown of a tooth. This type of restoration is typically used when a tooth has extensive decay or damage that cannot be adequately restored with a more conservative method, such as a filling. By encompassing the entire crown, a full crown provides strength, durability, and improved aesthetics for the tooth. Jacket crowns, while sometimes used to cover a tooth, usually refer specifically to a type of crown made from all-ceramic materials and are more commonly applied to anterior teeth to enhance appearance. Onlays are restorations that cover one or more cusps of a tooth but do not extend to cover the entire surface. Dowel crowns, used in more specific contexts, involve a post placed inside a root canal; they are often associated with teeth that have undergone root canal therapy but do not replace the entire tooth structure above the gumline in the way that a full crown does.
