NeoBurr® FG 331SS Short Shank Pear Operative Carbide Bur by Microcopy (USA). Engineered from a single piece of solid tungsten carbide with a compact short friction grip shank and an extended 1.8 mm pear-shaped cutting head featuring a 6-blade configuration. Specifically designed for pediatric dentistry and posterior teeth with limited interocclusal opening, delivering controlled cavity preparation, rounded internal line angles, and smooth axial wall contouring in Class I and Class II direct restorations.

Key Features:

• Short Shank Accessibility: Compact shank profile provides critical clearance, enhanced maneuverability, and clear line of sight in tight posterior quadrants and pediatric cases with restricted jaw opening.
• Stress-Free Pear Geometry: Gently rounded cutting contours eliminate sharp internal line angles, distributing occlusal stress evenly and optimizing cavity prep geometry for adhesive restorations.
• Extended 1.8 mm Cutting Flutes: Offers greater vertical reach compared to standard #330 burs, facilitating single-pass depth preparation and smooth axial wall definition.
• 6-Blade Precision Action: Precision-milled 6-blade design delivers smooth, chatter-free cutting and efficient debris removal while minimizing frictional heat on the pulp.
• Single-Piece Solid Carbide Construction: Integrated blended neck eliminates brazed joint failure points, maximizing fracture resistance under demanding clinical loads.
• Sterile Single-Patient Safety: Individually blister-packaged and pre-sterilized to prevent cross-contamination and ensure razor-sharp performance straight from the package.
• True Concentric Rotation: Precision Swiss-machined shank ensures true concentricity, protecting turbine chucks and handpiece bearings from premature wear.
