Majority of dental injuries involves tooth fractures in the front tooth region, especially in upper teeth due to their anatomical position. Anterior crown fractures lead to discomfort and serious psychological, esthetic, functional, and phonetic problems that can affect social relationships.
If the fracture is uncomplicated (i.e., not involving the pulp) and the pulpal health is uncompromised, it may be restored with composite resin or a jacket crown. In cases where the teeth are severely fractured, endodontic treatment and placement of intracanal posts become necessary, before crown restoration. A post and core crown is a type of dental restoration required where there is an inadequate amount of sound tooth structure remaining to retain a conventional crown. A post is cemented into a prepared root canal, which retains a core restoration, which retains the final crown. Post and cores are only placed in teeth that have already been root canal treated. And then, only for those that have large portions of natural tooth structure missing.
Basic steps involved in restoration of such badly broken tooth using post and core are as follows:
