When fabricating crowns or bridges, it is often necessary to reconstruct extensive sections of lost tooth structure with a core material. It is impossible to achieve sufficient anchorage of a restoration in the remaining dentin when a large portion of the crown has been lost. A post usually made of metal that is fitted into the prepared root canal of a natural tooth. When combined with an artificial crown or core, it provides retention and resistance for the restoration. Core is the center or base of a structure. Post and Core concept has been around for the past 300 years, as early as 1728 when Pierre Fauchard described the use of “tenons” as metal posts. Post and Core systems have evolved over time with the invention of many different types of posts based on cross sectional form, surface topography and esthetic requirements.
