The EZ-Fit post is the most advanced post in its' class. Unlike "dowel" fiber posts, the second tier prevents "bottoming out" which eliminates the high apical stresses under function common to other passive posts. The second tier actually compensates for the natural anatomical flare of the canal for optimum dentin-to-fiber contact, even distribution of stresses and maximum retention. The result is a more intimate and secure dentin-to-cement interface.
The EZ-Fit post head is grooved with undercuts that secure higher retention by locking-in the core material. The grooves of the EZ-Fit shank lock the post into the root providing high post retention.
