The Gracey 3-4 curette is used for subgingival scaling in anterior areas, similar to the 1-2, but with a slightly different shank angle that provides better access for certain anterior and premolar surfaces.
Key features:
- Used for subgingival scaling of anterior and premolar teeth
- Modified shank design for easier access
- Smooth adaptation to curved root surfaces
- Excellent control in tight or overlapping areas
