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.
1. Do I need a post after root canal?
After your tooth’s root canal therapy has been completed, your dentist may recommend the placement of a dental crown. If so, in some cases they may also inform you that a dental post and core (or else just a core without a post) must be placed before the crown can be made. Decision regarding placement of post will be done on remaining tooth structure present.
2. What are dental posts made of?
Dental posts are made from either titanium, titanium alloy, fibre or composite materials. Today, fiber-reinforced resin-based composite posts are the most common. Sometimes, depending on the size and condition, the dentist may place more than one post in a tooth (for example, in a molar).
3. Does a dental post hurt?
Placing a post in root canal treated tooth is a painless procedure which is done without anaesthesia.
4. What is the difference between a post and an implant?
Post is placed in root canal treated tooth when sufficient remaining tooth structure is not present to hold the crown where as Dental Implant is placed in the place of missing tooth to replace with artificial teeth.
5. What is a core build up for a crown?
When there is not enough tooth structure to support a permanent restoration such as a crown or a bridge, your Dentist may recommend one of two treatments: Either a Post and Core or simply a Core Buildup. The two procedures are very similar and they are used to literally build up the structure of the tooth.
6. Which post is good metal of fibre?
Metal is a traditional material which are stiff and cause root fracture where as fibre post is flexible and does not cause root fracture.
