- This rotary tool features a unique cross-cut blade geometry designed to aggressively section teeth and slice through tough materials with minimal effort
Uses
- Aggressive Material Removal:
- Slices through old, tough restorations like gold crowns, non-precious metals, silver amalgam fillings, and thick composite resins
- Rapid Cavity Preparation:
- Gains fast initial access through dense outer tooth enamel into carious dentin layers
- Tooth Sectioning:
- Efficiently splits multi-rooted teeth during complex or surgical extractions
- Axial Wall Shaping:
- Creates parallel wall channels and flat floors during crown and bridge preparation
Features
- Cross-Cut Blade Design (#1557):
- Engineered with razor-sharp horizontal notches intersecting the vertical fissure blades, which maximizes cutting aggression
- Bur Profile:
- Features a straight, cylindrical body finished with a smooth, domed (round) cutting end
- Friction Grip (FG) Shank:
- Designed with a standard-length friction grip connection for full compatibility with high-speed dental handpiece turbines
- Anti-Corrosive Plating:
- The underlying steel shank is nickel- or gold-plated to safeguard the instrument from rusting during intensive sterilization
Benefits
- Enhanced Cutting Efficiency:
- The cross-cut texture acts like miniature teeth on the blade edges, biting down aggressively into enamel to cut significantly faster than standard plain-cut fissure burs
- Protects Remaining Tooth Structure:
- The domed, rounded end eliminates sharp, jagged internal corners inside the prep, reducing microscopic fractures by evening out biting forces
- Stable Handpiece Control:
- Advanced shank plating eliminates internal slippage or micro-wobbling within the handpiece turbine, optimizing tactile control for the operator
- Autoclave Compatible:
- Fully built to withstand repeated steam, heat, and pressure sterilization cycles without losing edge sharpness
