Busch MicroPrep Diamond Bur Collection

The Busch MicroPrep line is a family of miniature diamond burs built for minimally invasive dentistry. Shorter working parts and reduced head diameters let you open a fissure, remove caries, or refine a small preparation while conserving the maximum amount of healthy tooth structure.

What Makes MicroPrep Different

• Reduced head sizes for micro-preparations and micro-invasive access cavities
• Available in medium grit for cutting and fine grit (red ring) for finishing the same shape
• Round, pear, cylinder round and flame geometries covering the full micro-prep sequence
• FG shank for high-speed handpieces
• Manufactured in Germany by Busch & Co. GmbH

Choosing a MicroPrep Bur

Start with a medium-grit MI figure to gain access and remove carious dentin, then switch to the matching fine-grit MI figure (the comparable 8000-series figure, e.g. MI 830 → MI 8830) to finish the cavity walls and margins. Because the shapes mirror each other across the grits, the preparation geometry stays consistent from access through finish.
