Clinical Applications
The cool diamant coarse diamond dental bur is suited for a variety of everyday and advanced dental procedures, including:
- Crown Preparation — efficient shaping and reduction of tooth structure for crown placement
- Cavity/Fissure Preparation — precise access and preparation of carious lesions and fissures
- Excavation — controlled removal of existing restorative materials
Why Choose Cool-Diamant?
The Cool-Diamant series is engineered for optimal cutting efficiency, helping to minimise heat generation during use. As a cool diamant coarse diamond dental bur, the CD 27G 010 FG is particularly well-suited to situations where aggressive stock removal is required without compromising precision. German engineering ensures consistent diamond particle distribution for reliable, repeatable results across every bur in 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.
