build-it! F.R.

Fiber-Reinforced automix core build-up system

Clinically proven, Build-It!® F.R. is now available in a very convenient Mini-Mix syringe. Now you can auto-mix without a gun. Get easier access to the preparation, better visibility and less waste.

Build-It!® F.R. is an ideal fiber-reinforced, dual cure resin core build up material conveniently delivered in a 25ml automix cartridge. Several innovations make Build-It!® F.R.: BETTER - FASTER - LESS EXPENSIVE.

BETTER

The addition of specially treated glass fibers (the same ones used in our Alert® condensable composite) increases the compressive strength of the core build up by more than 10% (249 MPa to 280 MPa*).

Build-It!® F.R. Core Material contains all of the features of an ideal core build up material - it cuts like dentin, it contains fluoride, it is available in a universal tooth color (approx. A2) and it is radiopaque for easy detection of marginal areas on x-rays.

Build-It!® F.R. Fiber Reinforced Core Material can be used under all-ceramic or all-composite restorations, or it may be used as a base restorative material in class 2 esthetic restorations using the directed shrinkage technique.

Build-It!® F.R. is available in four shades: dual cure A2, Opaceous White, self-cure Gold or Blue.

FASTER

Build-It!® F.R. is an automix system, just like impression material cartridges. Using the intra-oral tips, you can inject right into the preparation or into the Core-Forms. Core build-up has never been this easy.

LESS EXPENSIVE

With Build-It!® F.R., you don’t pay extra for the convenience – in fact, Build-It!® F.R. can cost up to 5 times less than comparative core materials. Also, the cartridge delivery system ensures that you mix exactly what you need – with only a small amount of waste in the mixing tip.

Build-It!® F.R.:

Is reinforced with special glass fibers for increased compressive strength
Features an auto-mix cartridge delivery system for greater convenience
Is both syringeable and stackable
Is dual-cure (light-cure or self-cure) to suit treatment modalities
Is fluoride-containing
Cuts like dentin
Is radiopaque for easy detection of marginal areas on X-rays
