Clinical evaluation of a glass hybrid system vs. a resin composite: preliminary findings of a multicentre trial

Abstract Body: Glassionomer cements (GIC) are classified as bioactive materials with strong, chemical adhesion to hard dental tissues through ion-exchange layer. However, despite these advantages, the mechanical properties of GIC have always been stated as their main shortcoming. One of the greatest breakthroughs in GIC technology, was the introduction of microlaminated system which consisted of fast-setting reinforced GIC and nano-filled resin coating applied on the GIC restoration. Clinical studies have confirmed that this EQUIA system can be used as a long-term aesthetic restorative material in the posterior region therefore offering alternative solution to amalgam restorations. The next step in evolution of restorative materials was glass hybrid technology which was released on the market by the name EQUIA Forte. This material is indicated for class I and class II restorations. Currently, split-mouth, randomized, prospective and multicentre clinical study is in progress with an aim to evaluate the clinical effectiveness of the glass hybrid material EQUIA Forte restorative system, as a long-term restorative material in moderate and large size two-surface restorations versus a nano-hybrid composite resin material. In the presentation the results of the study will be showed.
