Glass Fiber Posts from Itena North America
Composed of 80% glass fiber and 20% resin, Itena North America’s glass-fiber posts have an elasticity modulus very similar to dentin. This homogenous distribution of elasticity, much like that of a natural tooth, results in fewer failures than metal posts.
These glass-fiber posts have a cylindro-conical taper of 9% or greater, which mimics the anatomy of the root canal.
This makes insertion simpler and helps reduce the risk of root fracture.
The chemical retention created between the core build-up and the post creates a strong bond with no risk of corrosion or tissue discoloration. They have a flexural strength of 1650 MPa, shear strength of 760 MPa, and a compression strength of 760 MPa.
The posts are biocompatible, radiopaque, and come in translucent and ivory for the most esthetic results.
