    Objective: To compare the compressive strength of nanohybrid resin and bulk-fill resin using the incremental and monoincremental techniques. Methodology: Two types of resins were used: a nanohybrid resin and a bulk-fill resin. Both were molded into cylindrical shapes with dimensions of 8 mm in length and 4 mm in diameter. Cylinders formed using the incremental technique were created in 2 mm increments, while those formed using the monoincremental technique were created in 4 mm increments. These cylinders were subjected to compression testing using a universal testing machine, applying compressive force until fracture. Data analysis was performed using SPSS version 23 with the Student's t-test for independent samples. Results: The compressive strength of nanohybrid resin using the monoincremental technique was 254.90 ± 38.97 MPa, while for the incremental technique, it was 199.65 ± 44.29 MPa. On the other hand, the compressive strength of bulk-fill resin using the monoincremental technique was 226.36 ± 28.17 MPa, and for the incremental technique, it was 211.16 ± 19.97 MPa. Conclusion: The compressive strength of bulk-fill resin using the monoincremental technique was greater than that of nanohybrid resin using the incremental technique.
