The Frank Dental Parallel Chamfer Round End Crown Preparation Bur has been developed to provide clinicians with precise, smooth and predictable crown preparations for modern indirect restorations. Manufactured in Germany using high-quality diamond coating technology, this premium dental bur is ideal for creating accurate chamfer margins with rounded internal line angles, helping to reduce stress concentration within ceramic restorations.

The parallel chamfer design allows dentists to achieve excellent axial wall parallelism and controlled tooth reduction, making it particularly suitable for full coverage crowns, zirconia crowns, lithium disilicate restorations (E.max), crowns and other indirect restorations where precision and marginal integrity are critical.

The round end profile helps create smooth preparation margins while reducing the risk of sharp internal angles that can compromise the strength of ceramic materials. This design also improves restoration seating and supports improved fit, retention and long-term clinical performance.

Why Use a Parallel Chamfer Round End Crown Preparation Bur?

Dentists commonly choose a parallel chamfer round end bur when they require:

• Smooth chamfer margin preparation
• Conservative tooth reduction
• Rounded internal line angles for ceramic strength
• Improved restoration fit and seating
• Controlled axial wall preparation
• Predictable crown retention and resistance form
• Reduced stress concentration in all-ceramic restorations

The parallel-sided geometry helps maintain consistent preparation walls, making the bur highly effective for crown and bridge preparations where precision is essential.

Suitable Applications

The Frank Dental Parallel Chamfer Round End Bur is suitable for:

• Zirconia crown preparations
• E.max crown preparations
