    Aim: The aim of this study is to compare the compressive strength of different composite resins (Coltene SwissTEC, Ivoclar Tetric EvoCeram, and SHOFU Beautifil II). Background: The purpose of a dental restorative material is to simulate the biological, functional, and esthetic properties of a healthy tooth structure. Composite resins, due to their high esthetic properties, are being increasingly used in the recent past. Mechanical properties of posterior composites have an important role in the efficacy and durability of the restored tooth. Compressive strength, being the most important mechanical property of posterior restorative materials, owes a great deal to assess the quality of a posterior restorative material. This study, therefore, aims to compare the compressive strength of recently developed composites and analyze any significant differences making one better than the other. Materials and Methods: In this in vitro study, three different types of composites are used as follows: Group A – SwissTEC, a hybrid composite (Coltene Whaledent, Inc.); Group B – Tetric EvoCeram, a nanocomposite (Ivoclar Vivadent Inc.); and Group C – Beautifil II, a nanocomposite with Giomer technology (SHOFU Dental Corp). Ten cylindrical samples of 6 mm height and 4 mm diameter of each group were made using a custom split plexiglass mold. The composites filled in the mold were photopolymerized using light-emitting diode light-curing unit and the cured samples were stored in water at 37°C for 48 h before testing. The compressive strength of the stored samples was tested using a universal testing machine (M/S Zwick GmbH & Co., Germany) at a crosshead speed of 1.0 mm/min. The compressive strength was calculated by dividing the maximum load with area of the samples. Results: Results were statistically analyzed using one-way analysis of variance with Tukey’s post hoc test. Analysis showed that there was a statistically significant difference between the three groups (P < 0.05) and Giomer composite (Beautifil II) showed the highest compressive strength while the hybrid composite (SwissTEC) showed the least compressive strength. Conclusion: Within the limitations of the study, it can be concluded that Giomer exhibited superior compressive strength compared to the nanocomposite and hybrid composite.
