What Is a 1702 Bur?
The 1702 is the round end version of the 702 cross cut tapered fissure bur. It has a tapered head, cross cut blades and a rounded tip.
Round End vs Flat End Tapered Fissure Burs
A flat end bur leaves a sharp internal angle between the wall and the floor. A round end bur leaves a rounded angle, which is gentler on the tooth and easier to adapt a restoration to. The cross cut notches across the blades reduce chatter and clogging. The flat end version is the cross cut tapered fissure bur.
What the 1702 Bur Is Used For
Cavity preparation with tapered walls, and cutting through old restorations or crowns with less chatter. For the straight-sided round end version see the round end cross cut fissure burs.
