Wear and surface roughness of current veneered materials after toothbrush/dentifrice abrasion

The prosthetic composite materials have been improved and are now widely used for various kinds of prosthetic restorations. Three composite materials SR Chromasit, Palfique Estelite, and Palfique Toughwell were assessed, and SR Ivocron material was used as a reference material. The composite specimens polymerized with their proprietary curing units and were stored with the reference specimen in water for 14 days and subsequently subjected to toothbrush/dentifrice abrasion. The amounts of wear loss of each specimen after 20,000 strokes were determined. Palfique Toughwell composite material showed less wear and surface roughness than any of the other assessed materials.
