Abstract
A method and system for inserting a dental post into a tooth root canal. The method comprises the steps of cutting out a post hole in the tooth and inserting a threaded tap into the post hole for creating at least one groove along the hole. Significantly, the tap includes at least one slot defined by a pair of flexible legs and running at least a portion of the length thereof for reducing stress along the post hole during threaded insertion. Also provided is a lentulo drill comprising a spiraled wire with a reverse spiral configuration at the apical end thereof for confining cement placement in the post hole prior to insertion of the dental post.
