Post and core
post and corePost and core is a procedure in which a metal component of an extensive tooth repair is required to rebuild a tooth in order to provide proper support for a crown. Post and core is a thin metal rod that is cemented into the root of a tooth. It consists of a post that fits into the root canal and a core portion that project above the gum. A new replacement crown will be cemented into position over the core.
Why is a Post-and-Core necessary after Root Canal treatment?
Teeth that are treated for root canal problems are often badly broken down.
They need to be built up before they can have a replacement crown fitted over them.
Post-and-Core fabrication is the method of choice for the build-up process.
