Flame Diamond Burs - FG Flame Shaped Burs in Every Grit
Eagle flame diamond burs are FG (friction grip) diamond burs with a pointed, flame-shaped head, made for crown and bridge preparation, cavity preparation and finishing. The range covers 12 flame shapes, from the slim E52 to the long E68, in five grits from super fine to super coarse, so one product page covers bulk reduction, margin work and final finishing.
The tapered flame profile reaches proximal and cervical areas that cylinders and round-end tapers can't, and it follows the axial wall closely. That makes the dental flame bur a daily instrument for interproximal reduction during crown prep, feather-edge and vertical margins, and contouring composite and ceramic restorations.
What Is a Flame Bur Used For?
- Crown and bridge preparation - proximal and axial reduction, opening tight contacts
- Margin refinement - feather-edge and vertical (BOPT-style) preparations, smoothing finish lines
- Cavity preparation - shaping Class I, II and V cavities and opening fissures
- Veneer preparation - proximal extensions and refining preparation outlines
- Finishing and contouring - composite restorations, embrasures, occlusal anatomy and ceramic adjustments with fine and super fine grits
Grit Guide: Choosing the Right Flame Bur
Diamond grit is shown by the colored band on the shank. Work coarse to fine: reduce first, then refine and finish.
- Black band - Super Coarse: fast bulk reduction and removing old restorations
- Green band - Coarse: crown and bridge reduction
- No band - Medium: general preparation and cavity shaping
- Red band - Fine: margin refinement and composite finishing
- Yellow band - Super Fine: final finishing of margins, enamel, composite and ceramic
Not every code comes in every grit - pick the code first, and the selector shows the grits available for it. For a full explanation of grits and ISO numbers, see our dental burs guide.
Choosing a Flame Diamond Bur by Procedure
- Tight contacts and fine detail: slim heads such as E52 or E51
- Everyday crown prep and finishing: E5 or E8 (1.4 mm)
- Long axial walls and vertical preps: long flames - E53, E68, Z50 or Z51
- Larger surfaces and occlusal contouring: wider heads such as E6 or E9
Flame Bur vs Chamfer (Torpedo) Bur
A flame diamond bur tapers to a point, so it creates a feather-edge or knife-edge finish line and slips into proximal areas. A chamfer bur, such as a round-end taper or torpedo diamond, has a rounded tip that forms a defined chamfer margin. Many preparations use both: a flame to open contacts, then a chamfer or taper diamond to form the margin.
Shapes and Codes
Each Eagle code is listed with its equivalent ISO shape and size reference (shape number - head diameter in tenths of a millimeter), so you can match codes from other catalogs.
- E52 - flame 862-010, 1.0 mm: the slimmest flame, for tight contacts and fine detail
- E51 - flame 862-012, 1.2 mm
- E4 - flame 860-013, 1.3 mm
- E5 - flame 862-014, 1.4 mm: the all-round flame for crown prep and finishing
- E8 - flame 861-014, 1.4 mm
- E6 - flame 863-016, 1.6 mm
- E9 - flame 863-023, 2.3 mm: the widest flame, for larger surfaces
- E53 long - long flame 863-010, 1.0 mm
- E68 long - long flame 863-018, 1.8 mm
- Z50 long and Z51 long - long flame heads for extended axial walls
- PR2 - flame 390-018, 1.8 mm
See the size chart in the product images for the head shape of each code.
How to Use a Flame Diamond Bur
- Seat the FG shank fully in a high-speed handpiece and run it at the speed recommended by the handpiece and bur manufacturer.
- Use generous water spray to control heat.
- Work with light pressure and short, intermittent strokes - let the diamond cut.
- Hold the flame parallel to the planned path of insertion on axial walls.
- Move from coarse to fine grit on the same shape to refine the finish line.
Cleaning, Sterilization and Bur Life
Clean and sterilize flame burs before each use following your clinic's reprocessing protocol: pre-soak in a bur-compatible disinfectant, brush or clean ultrasonically in a bur holder, rinse, dry and autoclave in a pouch. Inspect each bur before use and replace it when it cuts slowly, has lost diamond, or the shank is bent. The most common causes of short bur life are heavy pressure, too little coolant and continuing with a dull bur.
