title: Retentive properties of a new post and core system.
abstract: Fifty Flexi-Posts were cemented in extracted teeth and tested for tensile strength. The Flexi-Post was the most retentive post tested when compared with posts used in a similar study. The retention of the Flexi-Post became greater as the size of the post increased.
