T-pins in a direct pattern technique for posts and cores.
Abstract
A practical direct technique for making post and core impressions with a T-pin and self-curing acrylic resin was described. Emphasis was placed on the function of the T-shaped plastic pin in fabricating the pattern. Clinical procedures for each step were described in detail. The unique characteristic of the T-pin of softening and becoming very sticky when exposed to direct contact with acrylic resin monomer allows soft acrylic resin to adhere to it, resulting in an accurate direct impression of the canal.
