- Parallel shape with grooves: great retention.
- Metal filament: allows radiographic visualization.
- Longitudinal fibers: easy removal.
- For use with Peeso (Largo) drills: easy adaptation in use.
- Optimal ratio between fiber and resin: high strength.
- Modulus of elasticity similar to dentin's: lower risk of root fracture.
- Glass Fiber: high esthetic resolution.
- Direct use (prefabricated): saves clinical time and decreases lab costs.
