A 10-year literature review of a split-shanked threaded post

A review of 10 years of literature on prefabricated threaded and passive post systems is presented along with recent literature supporting the validity of the split-shanked threaded post design, Flexi-Post. It is important to note that a split-shanked threaded post is altogether different from a solid-shanked threaded post. The research discussed in this article confirms the high retention of the Flexi-Post and dispels the notion that high retention must be accompanied by high stress.
