- This rotary instrument is explicitly engineered for high-speed dental handpieces to optimize the precise geometry needed for silver amalgam fillings
Uses
- Amalgam Cavity Preparation:
- Delivers the exact internal design required for silver amalgam placements by preparing flat floors and slightly undercut, converging walls
- Gaining Occlusal Access:
- Penetrates deep into pits and fissures of posterior molars and premolars to eliminate decay
- Restoration Removal:
- Slices cleanly through old composite resins or failing silver filling fragments during tooth replacement procedures
Features
- Elongated Pear Shape (#245):
- Features a unique pear-shaped silhouette with a lengthened cutting head and rounded corners to blend internal cavity dimensions
- Friction Grip (FG) Shank:
- Standard connection configuration ensuring a perfect, universal fit inside standard high-speed dental handpiece turbines
- Anti-Corrosive Shank Plating:
- The underlying steel shank is nickel- or gold-plated to prevent rust, discoloration, or degradation during strict chemical disinfection loops
- Clinic Packaging:
- Packaged and delivered in standard, convenient blister cards containing 10 burs per container
Benefits
- Built-In Mechanical Retention:
- The subtly converging walls and flat-floor profile naturally establish the precise undercuts needed to mechanically lock silver amalgam fillings in place without needing chemical bonding agents
- Prevents Stress Fractures:
- The rounded corners at the base of the pear shape eliminate sharp internal line angles, distributing biting forces evenly across the remaining tooth tissue
- Superior Cutting Stability:
- Premium shank plating provides an exact, micro-wobble-free lock within handpiece turbines, minimizing vibration chatter for better tactile precision
- Withstands Heavy Autoclaving:
- Crafted from heavy-duty tungsten carbide, the cutting edges resist premature dulling and structural fatigue through repeated high-pressure steam sterilization cycles
