Post and core. A post and core is a type of dental restoration required where there is an inadequate amount of sound tooth tissue remaining to retain a crown. A post is cemented into a prepared root canal, which retains a core restoration, which retains the final crown.
A post and core is indicated once an outsized part (or all) of a tooth’s original crown structure has been lost. The crown structure is broken either because of the progression of dental decays or due to a tooth trauma. A great deal of a dental crown stability depends on the extent of tooth structure present .If little tooth structure occupies this area, the crown are going to be simply dislodged, particularly by forces directed at its aspect.
Basically, the core is rebuilding the tooth therefore it’s nearer to its original dimensions. Hence, the crown’s stability can greatly increase, and so its long possibilities for fulfillment are maximized.
The benefit of placing a post into a root canal is improved retention of the crown.
