Carbide Flame Finishing Burs by Busch

Carbide flame finishing burs are the go-to instrument for contouring and finishing composite in tight spaces. The slender, pointed flame head reaches interproximal embrasures, gingival margins and facial line angles that wider shapes cannot, while the multi-blade carbide head cuts cleanly rather than grinding, leaving a smoother surface with less heat than a diamond.

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.

FAQ

What is a carbide flame bur used for? Contouring and finishing composite restorations, especially interproximal areas, gingival margins and embrasures where access is tight.

Carbide or diamond flame for finishing composite? Carbide is the primary choice for composite: it cuts rather than grinds, leaves a smoother surface and generates less heat. Diamond flames are better suited to enamel and ceramics — see our 862 Flame Diamond Burs.

Where are these burs made? Every bur in this collection is manufactured by Busch & Co. in Engelskirchen, Germany, and ships from our US warehouse.
