Use: 20 fluted TC burs to remove the bulk of the composite
An SEM and Profilometric study published in the JCO (January 2014) found :
‘the 12-fluted burs caused visible gouges on the enamel surfaces, while the use of 20-fluted and 30-fluted burs resulted in finer scratches’*
* Less enamel damage
* Non-clogging
* Long lasting
* Great price
* R/A (slow speed) or friction grip (high speed)
Recommended Speed: 25,000 - 30,000 RPM
Step 2
Use: a ceramic bur (choose shape according to tooth shape/contour) to remove any residual adhesive, safe in the knowledge they will not damage enamel.
10,000 Maximum RPM
Step 3
Use: a diamond polisher for final polishing. No paste is required as each filament is impregnated with diamond polishing particles, so the diamond grit is continually exposed for a high lustre finish.
5,000 Maximum RPM
