D.863.016.FG

The Frank Dental D.863 range of flame-shaped diamond burs are among the most versatile rotary instruments used in modern restorative and prosthetic dentistry. Commonly referred to as “flame burs”, these precision diamond instruments are widely used for composite contouring and finishing, while also playing a key role in the B.O.P.T. (Biologically Oriented Preparation Technique) feather-edge crown preparation protocol.

Manufactured in Germany using high-quality diamond technology, the Frank Dental D.863 burs provide exceptional control, smooth cutting efficiency and excellent tactile feedback for clinicians performing minimally invasive restorative procedures and advanced prosthetic preparations.

What Is a Flame Diamond Bur?

A flame bur is a tapered, pointed diamond bur with a smooth flame-like profile designed for:

• Fine contouring
• Interproximal finishing
• Cervical refinement
• Emergence profile shaping
• Feather-edge crown preparation
• Composite finishing and polishing

The slim tapered geometry allows clinicians to work accurately in difficult-to-access areas while maintaining excellent visibility and preserving surrounding tooth structure and soft tissues.

The Frank Dental D.863 range is available in multiple diameters and grit sizes to support both restorative and prosthetic workflows.

Frank Dental D.863 Burs for Composite Finishing

One of the most common uses for the D.863 flame burs is shaping and finishing composite restorations. The elongated flame geometry allows clinicians to refine restorations with precision while maintaining natural tooth anatomy and smooth transitional surfaces.

Ideal Uses for Composite Dentistry

The D.863 flame burs are ideal for:

• Composite contouring
• Composite finishing
• Interproximal composite refinement
• Cervical composite finishing
• Removal of excess composite
• Margin blending
• Finishing anterior composite restorations
• Refining posterior composite anatomy

The slim pointed design allows easy access into embrasures and interproximal areas where polishing discs or larger burs may struggle to reach.

Why Flame Burs Are Excellent for Composite Finishing

The flame shape allows:

• Controlled reduction of composite material
• Smooth blending between composite and enamel
• Reduced risk of flat spots
• Better anatomical shaping
• Improved surface smoothness before polishing
• Conservative finishing with minimal enamel removal

Fine and superfine grit D.863 burs are particularly useful during the final finishing stages of composite restorations before polishing systems are used.

Frank Dental D.863 Burs for B.O.P.T. Crown Preparation

The Frank Dental D.863 flame burs are also specifically suited for the B.O.P.T. (Biologically Oriented Preparation Technique) vertical preparation concept developed by Dr. Ignazio Loi.

Unlike traditional shoulder or chamfer crown preparation burs, the D.863 flame burs allow clinicians to create smooth feather-edge vertical preparations without defined finish lines.

What Is the B.O.P.T. Technique?

The B.O.P.T. technique is a feather-edge vertical crown preparation philosophy where:

• The soft tissues adapt naturally to the restoration contours
• No fixed finish line is created
• Emergence profiles guide gingival architecture
• Tooth structure is preserved
• Soft tissue aesthetics are enhanced

This technique is widely used for:

• Zirconia crowns
• E.max crowns
• Veneers
• Full mouth rehabilitation
• Highly aesthetic anterior restorations

Why the D.863 Flame Bur Works for B.O.P.T.

The smooth elongated flame-shaped geometry of the D.863 burs allows clinicians to:

• Create vertical feather-edge preparations
• Prepare within the gingival sulcus
• Avoid grooves and sharp ledges
• Produce smooth axial walls
• Shape natural emergence profiles
• Preserve biological width

The burs are specifically designed to work with the body of the bur rather than the tip during intrasulcular preparation, helping reduce irregularities that could interfere with gingival adaptation.

Frank Dental D.863.012 Long Flame Diamond Bur

The D.863.012 is a slim elongated flame bur ideal for:

• Fine anterior crown preparation
• Interproximal feather-edge preparation
• Sulcular preparation
• Composite margin finishing
• Cervical contouring
• Gingival emergence profile refinement

Its longer slim profile offers excellent precision and visibility during minimally invasive restorative procedures and advanced B.O.P.T. crown preparations.

Frank Dental D.863.016 Long Flame Crown Preparation Bur

The D.863.016 features a larger elongated working diameter for:

• Facial and palatal crown reduction
• Posterior crown preparation
• Full contour reduction
• Composite shaping
• Vertical crown preparation
• Zirconia and E.max preparation

The longer flame design improves access and cutting efficiency while maintaining smooth tissue-friendly preparation surfaces.

Multi-Grit Diamond System

The Frank Dental D.863 burs are available in multiple grit sizes:

• Green ring – Coarse grit for efficient reduction
• Red ring – Fine grit for refinement
• Yellow ring – Superfine grit for finishing and polishing

This sequential system allows clinicians to move from preparation to refinement while maintaining excellent surface smoothness and restorative precision.

Clinical Advantages of Frank Dental D.863 Flame Burs

• Ideal for composite finishing and contouring
• Excellent for B.O.P.T. feather-edge crown preparation
• Smooth elongated flame geometry for controlled preparation
• Minimally invasive restorative dentistry
• Enhanced soft tissue management
• Excellent interproximal access
• Suitable for zirconia and E.max crown preparation
• Available in multiple diameters and grits
