The purpose of this prospective randomised clinical trial was to evaluate the performance of two small-particle hybrid ormocer-based restorative systems (AD, Admira/Admira Bond, VOCO; DE, Definite/Etch & Prime 3.0, Dentsply) and one small-particle hybrid bis-GMA-based composite restorative system (TC, Tetric-Ceram/Syntac, Ivoclar-Vivadent) in class II cavities. Methods From one hundred and twenty-eight occlusal-proximal restorations (44 AD, 43 DE and 41 TC) placed in thirty-two adult patients, eventually seventy-seven (22AD, 29 DE and 26 TC) remained available for evaluation after 5 years.

Results After five years, eight AD, six DE and seven TC restorations had failed (p=0.10, logrank test). The main reason was fracture or marginal gap formation, while secondary caries accounted for four failures. In all restorations the quality of surface, margins and contact point decreased significantly compared to baseline. DE had a significant poorer color match (p <0.01). Statistical evaluation using the KW test showed that failures were concentrated on specific patients. Conclusions In a group of class II restorations, there was no significant difference in failures after 5 years between ormocer-based and bis-GMA-based restorative systems.",
