An abstract of the study, titled “Five-year performance of glass-hybrid and nano-hybrid restoratives: Multi-centre clinical trial”, was presented at the 2023 Oral Health Research Congress in Rhodes, which was organised by the continental European division and the Scandinavian division of the International Association for Dental, Oral, and Craniofacial Research.

The long-term randomised split-mouth trial, which was conducted at dental schools in Croatia, Italy, Serbia and Turkey, compared the clinical performance of EQUIA Forte with that of the nano-hybrid composite Tetric EvoCeram (Ivoclar) in medium to large Class II restorations. In the trial, 180 patients underwent two-surface restorations of two molars in the same jaw using each of the restorative materials according to random allocation. After a period of five years, no statistically significant differences were observed in the overall success and survival rates of the two types of restorative material.

At the congress, Lead researcher Prof. Ivana Miletić from the University of Zagreb’s School of Dental Medicine said: “After five years of follow-up, our results demonstrate an excellent long-term success of glass-hybrid restorative materials. I am optimistic about these materials’ expanding the restorative options without compromising the treatment outcomes for our patients.”

The full report on the study will be published in a special issue of the Journal of Dental Research.
