Tapered Shoulder Round Edge Crown Preparation Bur – 2.3mm Diameter (1.6mm Tip)
The tapered shoulder round edge crown preparation bur is designed for clinicians requiring efficient tooth reduction, smooth preparation geometry and precise shoulder margin creation for modern ceramic restorations. Featuring a 2.3mm maximum working diameter with a 1.6mm tip diameter, this diamond bur is ideal for larger crown preparations where greater reduction and enhanced access are required.
The tapered shoulder design with rounded internal edges helps produce smooth preparation margins while minimising stress concentration within ceramic restorations. This is particularly important when preparing teeth for zirconia, lithium disilicate (E.max) and other all-ceramic crowns where restoration strength and marginal integrity are critical.
The larger 2.3mm diameter enables rapid and controlled reduction of tooth structure, making the bur highly effective for:
- Full crown preparations
- Zirconia crown preparations
- Lithium disilicate (E.max) restorations
- All-ceramic crown preparations
- CAD/CAM restorative workflows
- Posterior crown preparations
- Rounded shoulder margin preparation
- High strength ceramic restorations
The 1.6mm tip diameter provides excellent stability and control while refining axial walls and shoulder margins. The round edge shoulder profile creates smooth internal transitions that help improve the fit and longevity of ceramic restorations while reducing the risk of stress fractures.
Manufactured using high-quality diamond coating technology, this crown preparation bur delivers efficient cutting performance, reduced vibration and excellent durability. The bur cuts smoothly and predictably, helping clinicians improve preparation accuracy, reduce chair time and enhance patient comfort.
