title: Direct pattern technique for posts and cores.
abstract: The technique described results in a well adapted cast post and core with good retention (Figs. 18 and 19). The chances of perforation of the root and trauma to the patient are reduced, and the expense of the procedure is minimal. This system is adaptable to single- or multirooted teeth and continually produces good results with minimal problems.
