Carbide Flame Finishing Burs by Busch

Which Carbide Flame Finishing Bur Do You Need?

Start with the standard figure 48 for contouring, use the long 48L for deeper reach, and finish with the fine and ultra-fine versions; the last three digits are the ISO head size, and every active product in the collection is linked once below.

Choosing the Right Carbide Flame Bur

• Figure 48 — the standard flame finishing carbide for contouring composite, in head sizes 009, 010, 012 and 014.
• Figure 48L — a longer flame head for deeper interproximal and facial reach.
• Figure 48F and 48LF — fine-grit finishing versions for smoothing after contouring.
• Figure 48L-UF — ultra-fine finishing for a pre-polish surface on composite.

Most instruments are FG (friction grip) for high-speed handpieces; the 48F is also available on an RA latch shank for slow-speed finishing.

Clinical Use

Carbide flame finishing burs are used for contouring and finishing composite restorations, especially interproximal embrasures, gingival margins and facial line angles. The FG burs run in the high-speed handpiece; the 48F 012 is also supplied on an RA shank for slow-speed finishing in the contra-angle.

Care and Reconditioning

Clean, disinfect and sterilize the instruments between uses following the manufacturer instructions and the symbols on each package, and replace an instrument once it loses cutting or polishing performance or shows damage. Our Dental Bur Reprocessing & Sterilization Guide covers the workflow for Busch rotary instruments; maximum speeds are in the Dental Bur Speed Chart.
