Frequently Asked Questions
What are composite finishing burs?
Composite finishing burs are multi-blade carbide (or fine diamond) burs used after curing to trim excess composite, shape contours and smooth margins before polishing. These are 12-blade tapered carbide finishing burs.
What are tapered carbide burs used for?
These 12-blade tapered burs trim and finish composite: removing excess material, shaping axial surfaces, smoothing margins and removing excess cement before polishing.
What is the difference between a tapered finishing bur and a tapered fissure bur?
A tapered fissure bur (169, 170, 171) has 6 blades and cuts cavity walls. This tapered bur has 12 blades and is a finishing bur, so it removes less per revolution and leaves a smoother surface.
What is the difference between 12-blade and 30-blade finishing burs?
A 12-blade bur removes material faster and is used for trimming and initial contouring. A 30-blade bur cuts more finely and is used for final finishing before polishing.
What is the difference between composite finishing and polishing burs?
Finishing burs shape and smooth the restoration. Polishing burs usually means rubber or abrasive polishers used afterward to bring up the luster. Finishing comes first, then polishing.
In what order do you use composite finishing burs?
Trim and contour with a 12-blade carbide, refine with a 30-blade carbide or fine diamond, then polish with cups, points, discs or paste. Check contacts and occlusion before the final polish.
What do 7205 and 7714 mean?
They are Eagle catalog codes for the two tapered 12-blade finishing burs on this page. Use the variant selector to choose the code.
Which handpiece do they fit?
