Clinical Applications
This coarse diamond cylinder dental bur is suitable for two primary clinical uses:
- Crown Preparation — enables efficient reduction and shaping of tooth structure for crown placement
- Cavity/Fissure Preparation — supports accurate preparation of cavities and fissures with consistent cutting performance
As a coarse diamond cylinder dental bur, the CD 30G 012 FG is built to handle high-demand cutting tasks while maintaining dimensional accuracy. The Cool-Diamant series from Busch reflects German engineering standards, ensuring reliable performance across multiple uses within the pack.
Independent Research: Test Winner at Innsbruck
In an independent laboratory study at the Medical University of Innsbruck, Busch’s COOL DIAMANT design achieved the highest cutting performance in both test series — outperforming same-shape, same-grit diamonds from up to ten competing manufacturers. Under standardized conditions (200,000 rpm turbine, constant 152 g load, 10–40 minutes of continuous cutting on 99.5% Al₂O₃ ceramic), the COOL DIAMANT instrument removed significantly more material than burs from Diatech, Edenta, Horico and Komet (p < 0.05), and in the second series the standard Busch diamond placed second only to its cooling-groove sibling. The authors concluded that instruments with cooling grooves deliver higher grinding performance and need replacing less often.
