Egg & Football Shaped Finishing Carbide Burs by Busch

Egg (football) finishing carbide burs are the shape of choice for occlusal anatomy: the oval head follows cusp inclines and fossae without flattening them, and the multi-blade carbide cuts composite cleanly rather than grinding it. Busch & Co. makes the 44E series in Germany in three sizes and three blade counts, and each one carries the US number American practices order by.

Which Egg Finisher Do You Need?

US No.	Busch No.	Head	Blades	Shanks	Stage
7404	44E 014	1.4 mm	Standard	FG, RA	Contour, premolars
7406	44E 018	1.8 mm	Standard	FG, RA	Contour, molars
7408	44E 023	2.3 mm	Standard	FG, RA	Contour, broad surfaces
8406	44E-F 018	1.8 mm	Fine (16–22)	FG, RA	Smooth
9406	44E-UF 018	1.8 mm	Ultra fine (30)	FG	Pre-polish

Clinical Uses

Occlusal contouring: shaping cusp inclines, marginal ridges and fossae in posterior composite after placement.
Lingual finishing: refining the concave lingual surfaces of anterior composites, veneers and crowns.
Amalgam carving and finishing: smoothing occlusal amalgam at the finishing appointment.
Pre-polish: the F and UF grades leave a surface that two-step diamond polishers bring to a high gloss in seconds.

Sequence

Contour with the standard 12-blade class egg (7404, 7406 or 7408 by size), smooth with the fine 8406, and finish with the ultra-fine 9406 before polishing. Same shape, same size, increasing blade count, so the anatomy you carved in the first pass is preserved through the last.

FAQ

What is the US number for the Busch 44E? 44E 014 is US No. 7404, 44E 018 is US No. 7406 and 44E 023 is US No. 7408. The fine 44E-F 018 is US No. 8406 and the ultra-fine 44E-UF 018 is US No. 9406.

Egg or football, what is the difference? None. Both names describe the same oval finishing head; US catalogs tend to say egg, European catalogs football.

Which size should I stock? The 1.8 mm No. 7406 covers most posterior work. Add the 1.4 mm 7404 for premolars and tight anatomy and the 2.3 mm 7408 for large molar restorations.

Carbide or diamond for finishing composite? Carbide. It cuts rather than grinds, leaves a smoother surface and generates less heat, which is why every bur in this collection is a multi-blade carbide. Diamond eggs belong on enamel and ceramic; see our Egg & Football Diamond Burs.
