Q.P Fiber Post FAQ
The Elastic Modulus is a calculated measurement of the relative rigidity of the material.
Lower modulus indicates more flexibility, and it is inherent to the material, regardless of size or diameter.
Flexural Strength is measured in a 3-point bending test and quantifies at what load (under very specific standardized conditions) the material breaks.
The Flexural Strength is related to diameter; the larger the diameter, the higher the flexural strength.
The low Elastic Modulus of the fiber posts helps prevent root fracture. The higher the Flexural Strength of the post, the more durable the restoration will be.
