Why Choose Eagle Inverted Cone Diamond Burs?

Optimal Shape for Clinical Versatility

The inverted cone profile is specifically engineered to create undercuts, divergent cavity walls, and retention features that are difficult or impossible to achieve with parallel-sided burs. This unique geometry makes them indispensable for a wide range of restorative and prosthetic procedures.

High Cutting Efficiency

Premium diamond particles bonded to a durable substrate provide aggressive, efficient cutting action that removes tooth structure quickly while maintaining precise control. The consistent grit distribution ensures uniform cutting performance across the entire working surface.

Precise Control and Smooth Finish

Despite their aggressive cutting ability, inverted cone diamond burs deliver exceptional control and leave smooth preparation surfaces that minimize the need for additional finishing steps. This saves chair time while improving patient comfort.

Superior Durability and Longevity

High-quality diamond particle bonding and robust construction mean these burs maintain their cutting efficiency through multiple procedures and sterilization cycles, providing excellent value for your practice.

Clinical Applications

Cavity Preparation

Ideal for creating retention features, establishing divergent walls, and developing undercuts in Class I, II, and V cavity preparations. The inverted cone shape naturally creates the divergence needed for proper retention.

Crown Preparation

Excellent for establishing shoulder and chamfer margins, creating retention grooves, and developing axial wall divergence in crown and bridge preparations. The shape allows precise control when preparing subgingival margins.

Removing Restorations

Efficiently removes old composite, amalgam, and temporary restorations. The inverted shape provides excellent access for sectioning crowns and cutting through restorative materials.

Adjusting Existing Restorations

Perfect for contouring and adjusting ceramic, composite, and metal restorations. The inverted cone profile reaches interproximal areas and margins that other bur shapes cannot access easily.

Endodontic Access

Creates divergent access cavities for endodontic procedures, providing straight-line access to canal orifices while preserving coronal tooth structure. Particularly useful for opening calcified chambers.

Retention Groove Preparation

Establishes retention grooves in crown and pin preparations where mechanical retention enhancement is needed.

Grit Selection Guide

Medium Grit

• Balanced cutting and finishing
• Ideal for routine cavity preparations
• Good for final shaping and margin refinement
• Smoother surface finish
• Recommended for preparations requiring less aggressive removal

Coarse Grit

• Maximum material removal efficiency
• Best for initial crown preparation
• Excellent for removing old restorations
• Faster cutting action
• Use when bulk reduction is needed

Professional Usage Guidelines

Speed and Technique

• Operate at high speed (150,000-400,000 RPM) with adequate water coolant
• Use light, intermittent pressure—allow the diamond to cut
• Employ steady, controlled movements
• Avoid prolonged contact to prevent heat generation

Maintenance

• Clean thoroughly after each use to remove debris
• Sterilize according to standard autoclave protocols
• Inspect regularly for worn diamond coating
• Replace when cutting efficiency diminishes

Safety Considerations

• Always use with copious water spray to prevent thermal damage
• Maintain proper handpiece maintenance for optimal performance
• Ensure adequate visibility and patient positioning
