Carbide finishing burs make up most of this collection. For the slender flame shape used interproximally and at gingival margins, go straight to our Carbide Flame Finishing Burs; for every flame option in carbide and diamond, see All Flame Burs.

Shop Finishing Burs by US Number

Every Busch finisher that has an American counterpart carries its US number in the title, so you can reorder by the number you know: round finishers 7002–7009 (fine 8006), bud finishers 7102–7108, pear finishers 7303 and 7304, egg finishers 7404, 7406 and 7408 (fine 8406, ultra-fine 9406), round-end tapers 7675 and 7686, and the 242 flame. The full index is on our US Bur Number Finder.

Composite Contouring and Finishing Burs

Most of the burs on this page are chosen for one job: finishing composite. The sequence is simple. 12-blade carbides in flame, football and tapered shapes contour the restoration — occlusal anatomy with the football, interproximal areas with the flame, facial surfaces with the taper. 20 to 30 blade finishing carbides then remove the micro-roughness the contouring pass leaves, without scratching the resin. Fine-grit diamonds play a supporting role at the enamel margins, blending composite into tooth structure before polishing. Carbide is the primary choice for composite because it cuts rather than grinds: it produces a smoother surface, generates less heat than diamond, and lowers the risk of microfractures at the margin. Our guide to the best burs for composite walks through each step with specific Busch instruments.

FAQ

Which burs are best for composite contouring? 12-blade carbide burs — flame for interproximal areas, football for occlusal anatomy, tapered for facial surfaces. They sculpt the restoration cleanly without the heat and chipping risk of coarse diamonds.

Which burs are best for finishing composite restorations? 20 to 30 blade carbide finishing burs. The higher blade count removes micro-roughness and leaves a surface ready for polishing; diamonds are reserved for fine-grit work at enamel margins.

What do the 7000, 8000 and 9000 US numbers mean? The 7000 series is the standard 12-blade class finisher; the 8000 series is the same shape and size with a fine blade count; the 9000 series is the 30-blade ultra-fine version. A 7406, 8406 and 9406 are the same 1.8 mm egg at three finishing stages.

What materials are Busch Dental Finishing Burs compatible with? They are suitable for composite resins, ceramics, amalgam, and metal alloys, making them highly versatile across restorative procedures.

Are these burs compatible with standard handpieces? Yes, Busch Dental Finishing Burs are designed to fit standard high-speed and low-speed dental handpieces with industry-standard shank sizes.

How do I select the right bur shape for my procedure? Shape selection depends on the restoration type and access requirements. Flame and tapered shapes suit margin finishing, while cylinder and bullet shapes are preferred for flat-surface contouring and occlusal refinement.
