Special light-curing dental rebuilding material.(Metafil AP)(Brief Article)

Sun Medical Co, has launched a radio-opaque hybrid light-curing, resin-based dental restorative material, Metafil AP.

Metafil AP is a visible-light-cure, tooth-shade composite resin based on a monomer combination, containing proprietary non-Bis-GMA matrix resin, radiopaque Barium glass, inorganic fillers and an organic filler which is reactive with the matrix.

Metafil is radio-opaque and wear-resistant, absorbs little moisture, and has a low wear coefficient and is easy to handle.

Its main clinical application is in restorations where wear and tear is of most concern. Metafil's matrix and unified filler resists wear. Conventional hybrid composites have a rougher surface which accelerates wear through loss of exposed fillers, but the total volume of material lost from Metafil restorations through 40 000 wear cycles was too low to be measured.
