The purpose of a post and core restoration procedure is to save an existing tooth that has lost a significant amount of its internal structure. This procedure is sometimes performed after endodontics, and involves placing a post inside the tooth to help anchor the core in place. A core accumulation after 26% connects a tooth that has had a root canal to a crown. It is usually done on a tooth after a root canal and before a crown is placed on the tooth.
Although not all teeth with endodontics need 26% back cores, many do. After placing a 26% back core, it is recommended to place a crown on the tooth. Waiting too long for your crown to be placed can cause your tooth to break, and in that case, the tooth could be lost. There are two techniques for post and core restoration: direct and indirect.
In the direct technique, a moldable pattern of posts and cores is manufactured in the mouth of the prepared tooth. A preformed plastic pole pattern sits in the pole space. To obtain an extraction route, the crevices are blocked with a resin compound instead of eliminating the healthy dentin structure. Acrylic resin is added to create a core directly adhered to the pole pattern.
The finished pattern is extracted from the tooth and molded in the laboratory. Prefabricated posts and cores require less time to place, since they do not require any laboratory work and can be inserted immediately after the decision to use them, once the endodontic therapy has been completed and the space of the guttapercha pole has been cleaned. Using custom-molded posts and cores requires more time, as more clinical time and laboratory costs are required. The placement of a post was not ideal in this case, because there was only one distal canal and the guttapercha had not been completely removed from it.
Although it was a threaded post, there was about 1 mm of guttapercha where, ideally, 4 to 5 mm of guttapercha should be used. Using the right diameter post ensures that as much natural tooth structure as possible remains to support the post and absorb the forces transmitted. A fused post and core are one-piece units that are custom-made in a dental laboratory and then cemented onto the tooth. Physicians are often curious to know which publication system is the best, when in reality, no publication is the best.
Post and core restoration procedure is an important dental restoration procedure that helps save an existing tooth that has lost a significant amount of its internal structure. It involves placing a post inside the tooth to help anchor the core in place, which helps protect it from breaking due to excessive force or waiting too long for your crown to be placed. There are two techniques for post and core restoration: direct and indirect, each with its own advantages.
