Nebraska 12B

Key Features

1. Design and Shape:

   • Rotary Burr: The Nebraska 12B is a type of rotary bur, designed to be attached to a dental handpiece for high-speed cutting.
   • Shape: The bur typically features a round or pear-shaped head with multiple cutting surfaces or flutes. The specific shape and size of the bur are designed for efficient removal of carious dentin while preserving healthy tooth structure.

2. Material:

   • Construction: Made from high-quality tungsten carbide or diamond-coated materials to ensure durability and effectiveness in cutting tooth structure.
   • Shank: Designed to be compatible with standard dental handpieces, allowing for easy attachment and use.

Usage

• Cavity Preparation: Used to remove decayed or damaged tooth structure and create the ideal shape and size for dental restorations such as fillings or crowns.
• Tooth Reshaping: Can be used to reshape teeth for cosmetic purposes or to correct minor irregularities in tooth structure.
• Material Removal: Effective for removing old or defective dental restorations, such as amalgam fillings or composite resin.

Maintenance

• Sterilization: Must be properly sterilized between uses to maintain asepsis and prevent cross-contamination. Autoclaving is the standard method of sterilization for dental instruments.
• Replacement: Burs may need to be replaced periodically due to wear or damage to the cutting surfaces.
