Ring-opening monomers with a reduced shrinkage stress “silorane" are being
used as matrix resins for recently introduced dental composites. Thisstudy aimed to analyzethe
mechanical behavior(Flexural StrengthFS, Abrasion Resistance AR) of the silora
ne-based composite
(Filtek P90) in comparison to two methacrylate-based composites (Tetric- Evo Ceram & packable
hybridTetric Ceram HB).
