Cutting Performance Comparison of FG 330 EdgeDental Carbide Burs

Biomaterials Research Report Matt Cowen, B.S. DENTAL ADVISOR Biomaterials Research Center


Introduction: This study compares the cutting efficiency and durability of FG 330 Carbide Burs and provides a visual SEM comparison of the bur products before and after cutting. A custom bur test jig utilizing an electric handpiece and a specimen carriage that holds the substrate while the carriage is pulled into the rotating bur is used to perform the testing. The system is driven by a universal test machine crosshead that was programmed to deliver a constant force when pulling the carriage.
