The Round Operative Carbide Surgical FG Burs are ideal for initial entry, excavating infected dentin, extending preparation walls, creating retentive features, and endodontic access. The smaller head diameters help create ultra-conservative preparations. The Straight Round End Operative Carbide Surgical FG Burs create a preparation with parallel walls and a flat floor. They are useful for establishing the periphery of a preparation. Cross-Cuts increase cutting efficiency and facilitate cutting dentin at lower speeds for improved tactile response. Dome Ends create rounded internal line angles to distribute occlusal forces. The Straight Flat End Operative Carbide Surgical FG Burs are Cross-Cut burs that feature traditional head shapes with maximum density cross-cuts in the bur blades to dramatically increase cutting efficiency while simultaneously decreasing undesirable chatter, friction and clogging. Perfect for rapid reduction or crown removal. The slightly roughened preparation surface is ideal for improving micromechanical retention in composite preparations. Fine Cross-Cut burs are available in a wide variety of shapes to meet every clinical situation. Cross-Cuts increase cutting efficiency and facilitate cutting dentin at lower speeds for improved tactile response x2. The Taper Round and Flat End Operative Carbide Surgical FG Burs create diverging preparation walls ideal for indirect restorations. CrossCuts increase cutting efficiency. Dome Ends create rounded internal line angles to distribute occlusal forces better. Tapered shape helps maintain full-length enamel rod margins on convex tooth surfaces Features and Benefits Non-sterile Available in a variety of shapes
