Bud Dental Burs

Bud dental burs are rotary instruments with a teardrop-shaped head, rounder and shorter than a football bur, built for controlled contouring in tight interproximal and occlusal spaces. This collection holds Busch carbide bud cutters (No. 424 and crosscut No. 424X, HP shank), Busch carbide finishing bud burs (No. 46, sizes 009–023, FG shank; US No. 7102–7108) and Busch steel bud cutters for acrylics and plaster (No. 75, No. 79 and crosscut No. 85, HP shank), all made in Germany for clinical and laboratory use.

The compact bud shape reaches where longer instruments can't, making it a go-to for opening and shaping proximal contacts, refining occlusal anatomy, and general laboratory model trimming.

Which Bud Bur Do You Need?

Choose the FG finishing burs (No. 46) for chairside composite work, the carbide cutters (No. 424/424X) for acrylic trimming on the straight handpiece, and the steel cutters (No. 75, 79, 85) for plaster and acrylic model work.

Clinical and Laboratory Use

Chairside, the FG finishing bud burs contour and finish composite in interproximal and occlusal spaces and open and shape proximal contacts; in the laboratory, the HP carbide and steel bud cutters trim acrylic prostheses and plaster models where a longer instrument cannot reach. Run every bur at the speed recommended for its material and shank — see our Dental Bur Speed Chart.

Care and Reconditioning

Busch rotary instruments are reusable: clean, disinfect and sterilize them between patients according to the manufacturer’s instructions. Our Dental Bur Reprocessing & Sterilization Guide walks through the workflow for carbide, diamond and steel instruments.
