Dental Burs Shapes

There is wide range of dental burs shapes available which can make it extremely hard to decide which suits you the best. Different flute angles create different cutting characteristics, making each bur appropriate for a particular task.

Trimming and finishing burs will have more blades that are closer together and much shallower making them perfect for fine finishing and polishing. The most used bur head shapes include round, pear, cylinder, inverted cone, cross-cut tapered fissure.
