After endo, what supports the crown?
There are two causes of common failures in posts and implants: retention and stress distribution. Implants that were smooth metal cylinders have today become threaded metal cylinders. By using one additional hand-operated instrument, the thread cutter and an additional five minutes of time, a rigid, threaded, metal post can be placed in the root canal to support the remaining coronal dentine. The tooth can frequently be rebuilt as a single unit or a bridge abutment to last for as long as the bone supports the root. To thread or not to thread, was that the question?
