Clinical Applications

The cool diamant diamond cylinder dental bur is well-suited for the following procedures:

• Crown Preparation — precise axial and occlusal reduction for full and partial coverage restorations
• Cavity/Fissure Preparation — accurate cavity outline and fissure access for composite or amalgam restorations
• Excavation — efficient removal of existing restorative materials with minimal trauma to surrounding tooth structure

Why Choose the Cool Diamant Series?

Engineered and manufactured in Germany, the cool diamant diamond cylinder dental bur reflects Busch & Co.'s long-standing commitment to precision and consistency. The medium grit formulation strikes a balance between cutting speed and surface quality, making it a reliable choice for everyday clinical use. Each bur in the CD 27 010 FG range is produced under strict quality controls to ensure dimensional accuracy and consistent diamond particle distribution.

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.
