Tapered Shoulder Round Edge Crown Preparation Bur – 1.8mm Diameter (1.2mm Tip)
The tapered shoulder round edge crown preparation bur is designed for precise and efficient crown preparations where smooth margins, controlled reduction and restorative strength are essential. With a 1.8mm maximum diameter and a narrower 1.2mm tip diameter, this diamond bur provides excellent balance between rapid tooth reduction and detailed margin refinement.
The rounded shoulder design creates smooth internal line angles, helping to reduce stress concentration within ceramic restorations and improving the long-term durability of zirconia and lithium disilicate crowns. The tapered shape assists clinicians in achieving ideal axial wall convergence while maintaining excellent visibility throughout the preparation procedure.
This dental crown preparation bur is ideal for:
- Zirconia crown preparations
- Lithium disilicate (E.max) restorations
- All-ceramic crown preparations
- CAD/CAM crown preparations
- Full coverage crown preparations
- Rounded shoulder margin creation
- Anterior and posterior restorative procedures
The 1.8mm working diameter allows efficient occlusal and axial reduction, while the 1.2mm tip diameter provides improved control when refining preparation margins and working interproximally. The round edge shoulder profile is particularly beneficial for ceramic restorations where smooth transitions and adequate material thickness are critical for restoration strength and fit.
Manufactured with a high-quality precision diamond coating, this bur delivers smooth cutting performance, reduced vibration and excellent cutting efficiency, helping improve both clinician control and patient comfort during crown preparation procedures.
