SS WHITE FG CARBIDE BURS #245 S PKG.10
Vendor: SS White
SKU: ISS16F
Product Description:
The SS White FG-257 is a precision-engineered round-end tapered fissure carbide bur designed for operative dentistry. It features a tapered body that narrows toward a rounded (dome) tip, allowing for efficient shaping and contouring during cavity preparations.
In my own words, the #257 is a "dual-purpose" shaping tool. It is specifically designed to create the tapered side walls needed for restorations to fit perfectly, while the rounded tip ensures the floor of the cavity is smooth and free of sharp angles. These rounded internal corners are vital for "stress-proofing" the tooth, as they help distribute biting pressure more evenly and prevent the tooth from cracking later on. As a plain-cut bur, it shaves the tooth structure smoothly rather than sawing into it, leaving a clean, polished finish that is ideal for bonding and final impressions.
Key Advantages:
- Structural Integrity: The dome end eliminates sharp stress points, increasing the longevity of the natural tooth.
- Precision Tapering: The tapered profile is ideal for creating the specific wall angles required for indirect restorations.
- Refined Surface: Plain-cut blades offer a "chatter-free" experience and leave a smooth surface ready for adhesive dentistry.
- High-Speed Durability: Made from premium fine-grain tungsten carbide to ensure the bur remains sharp and stable at high RPMs.
