Since mounted stones are rarely perfectly round and concentric, they have a tendency to hammer the restoration, as do carbide finishing burs. This excessive vibration can dislodge the fillers from a restorative's matrix, leaving irregularities on the surface of the restoration.
Our micron diamonds are manufactured with an extremely uniform coating of 50 Micron and 25 Micron diamond grits. This allows the instrument to cut smoothly, without causing vibration or damage to the composite or glass ionomer materials. These rotary diamond instruments should be used with minimal pressure, in a constant wiping motion, using a generous amount of water.
Use the 50 Micron diamonds to shape and contour the final structure of your composite or glass ionomer restorations. The extra fine rotary abrasion of the 50 Micron diamond quickly cuts the restorative with minimal damage to the matrix material. Maximum Recommended Speed 50,000 RPM.
Use the 25 Micron diamonds to make your final adjustments to your restoration and to smooth the surface of your composite or glass ionomer restorations. The ultra fine rotary abrasion of the 25 Micron diamond leaves the surface of your restoration very smooth, often eliminating the need for any further finishing. Maximum Recommended Speed 15,000 RPM.
