Fiber-Reinforced Composite

By the Dental Nation clinical team — a licensed dental group practising in the UAE

Fibre reinforcement can improve fracture resistance in structurally compromised teeth when placed with the right technique.

^[1][2]

The short answer

Fiber-reinforced composite can improve fracture resistance in structurally compromised teeth, and its placement technique matters.

^[1][2]

What is fiber-reinforced composite?

Two fibre materials and their reported placement
Material	Reported placement
Ribbond	A single layer can be placed at the cavity floor.^[1][2]
EverX Posterior	It replaces missing dentin in an anatomically shaped form.^[1][2]

^[1][2]

What property can it improve?

Both fibre types improved fracture resistance in structurally compromised teeth. The reviewed materials were equally efficient for fracture mode.

^[1][2]

Where can the fibres be placed?

Ribbond can sit as one layer on the cavity floor. EverX Posterior is used to replace missing dentin in an anatomical shape.

^[1][2]

How does it differ from conventional composite?

Studies have compared fibre-reinforced composite with bulk-fill, bulk-fill flowable, and conventional resin composite in endodontically treated teeth.

^[1][2]

Why does the placement method matter?

The two fibre materials use different placement methods: one layer at the cavity floor for Ribbond, or anatomically shaped replacement of missing dentin for EverX Posterior.

^[1][2]

What should be considered for strength and safety?

Fibre reinforcement improved fracture resistance in the reviewed structurally compromised teeth, but the material needs to be applied using its stated technique.

Findings for the two fibre materials

Frequently asked questions

Can fiber-reinforced composite make a weakened tooth more resistant to fracture?

Both fibre types improved fracture resistance in the reviewed structurally compromised teeth.
