The Glass Hybrid technology represents the next big leap in restorative dentistry. EQUIA Forte follows the hugely successful EQUIA restorative system which was launched in 2007. A long-term multicenter study was initiated in 2015 to assess the clinical performance of EQUIA Forte compared to a nanohybrid composite resin (Tetric EvoCeram®, Ivoclar Vivadent) in medium to large Class II restorations.
