Abstract
Aim: The purpose of this study was to evaluate the cusp deviation of teeth that had been repaired using a novel free Bis-GMA composite resin. Materials and Methods: Eighty freshly removed premolars (n=80) with Class II (MOD) cavities were employed in the study. The teeth will be separated into two equal groups (n=40) based on the kind of composite resin utilised, with each major group broken into two equal subgroups (n=20) based on the adhesive system. Subgroup a: Admira low-shrinkage composite resin with Futurabond DC adhesive system. Subgroup b: Admira, a low-shrink composite resin with G-bond. Subgroup c: Grandio Bis-GMA Containing Resin Composite with G-bond (subgroup c). Subgroup d: Futurabond DC with Bis-GMA Containing Resin Composite (Grandio). A universal measuring microscope and a laser horizontal metroscope were used to measure cusp deviation. Results: The considerable increase in cuspal deviation of cavities repaired using Bis-GMA Containing Resin Composite (Grandio) over the low shrinkage composite resin Admira was expected. Conclusion: Due to changes in the organic matrix of the material, Admira (Ormocer) has a good effect on limiting cusp deviation when compared to traditional Bis-GMA Containing Resin Composite (Grandio).
