- A precision endodontic tool used specifically for countersink preparation in the final stages of canal shaping
Uses
- Creating a Countersink:
- Preparing a recessed "seat" to accommodate the wider head and coronal shank of a Size 3 post
- Refining Post Fit:
- Ensuring the post head sits flush with or slightly below the tooth surface for a stable core build-up
- Final Shaping:
- Completing the two-stage drilling process required for the anatomically shaped Pac-Flex system
Features
- Size & Color-Coding:
- Coded Green to match all Size 3 instruments and posts in the system
- Specialized Cutting Tip:
- Designed to widen only the entrance of the canal without affecting the depth or diameter of the deeper apical preparation
- System Integration:
- Fully compatible with both Stainless Steel and Titanium Size 3 Pac-Flex posts
Benefits
- Increased Stability:
- By creating a custom seat for the post head, it maximizes the surface contact between the post and the tooth, preventing movement
- Fracture Resistance:
- Ensures the post is properly recessed, which helps distribute biting forces more evenly across the root and reduces stress concentrations
- Procedural Accuracy:
- The color-coded system (Green) prevents the use of mismatched drills, ensuring the preparation perfectly fits the 1.70mm Size 3 post
