- As the largest size in the standard sequence, it is used to precisely shape the root canal to accommodate a matching Size 3 dental post
Uses
- Final Channel Sizing:
- Used for the final preparation of the primary post space in larger root canals, such as those found in maxillary central incisors or large canine roots
- Precision Reaming:
- Calibrated to create a space that perfectly matches the 1.70 mm diameter of a Size 3 Pac-Flex post
- Foundation Support:
- Provides the structural channel necessary to support high-retention restorations in teeth with significant loss of natural crown structure
Features
- Diameter:
- Features a precise 1.70mm diameter
- Color-Coding:
- Coded Green for immediate identification as a Size 3 instrument, matching the color on the Size 3 refill kits
- Tapered Tip:
- Designed to provide a smooth, guided transition between the post and the root canal, minimizing the risk of root perforation or ledging
- System Integration:
- Compatible with both Stainless Steel (PSS3G-10) and Titanium (PTS3G-10) Pac-Flex posts
Benefits
- Optimized Retention:
- By creating a channel that exactly mirrors the post dimensions, it ensures the sharp threads of the post can properly engage the dentin
- Enhanced Stability:
- The large diameter is ideal for providing maximum stability in wide canals where smaller posts might be insufficient
- Hydrostatic Pressure Relief:
- When used in conjunction with Pac-Flex posts, which feature venting channels, it helps avoid pressure buildup during the final cementation phase
