Practical technique for the fabrication of a direct pattern for a post-core restoration

Abstract

1 he pulp chambers of teeth vary considerably in their mesiodistal-labiolingual sections1 Preparation of these pulp chambers, particularly those of the canines and premolars, to receive a cylindrical prefabricated post will mean unjustifiable removal of tooth structure or relying on the cementing medium alone to offset the lateral forces of mastication. An accurate and manageable technique for a cast core post should be part of a restorative dentist’s armamentarium. The following is a direct-pattern technique for posts and cores made with a cold-curing acrylic-resin* and prefabricated plastic posts.? This technique is a modification of those already reported in the literature.2M8
