The pear shape and structured blank design provides additional chip and hollow spaces which ensure efficient and quick removal of large amounts of composite right from the first rotation of the bur. Also, its innovative, active tip allows for axial drilling. Other features and benefits include:

  • Grit: Medium
  • Size: 012

Filling removal with 4COMP diamond bur.

Drill out composite fillings in the usual manner Amalgam restorations are removed by cutting several longitudinal and transversal separation grooves
Recommended use

Can be used the same as the amalgam remover H32 by drilling into the filling in an axial direction or from an inclined position (fig. 1). Drill out composite fillings in the usual manner. Amalgam restorations are removed by cutting several longitudinal and transversal separation grooves, depending on the size of the filling (fig. 2). By cutting the filling into several smaller segments, some fragments of the filling might already break off the cavity. Finally, any residual filling material is then removed with suitable manual instruments (or with the H32).

Recommendations for Use:

Recommended speed is 160,000 rpm in a red contra-angle. The instrument can also be used in a dental turbine.

4COMP Structured Blank Design

Structured Blank Design of Komet 4Comp Filling Removal Diamond Bur

A structured blank bur combines a blank side and a diamond side for increased efficiency when removing substances. The blank side reduces clogging and the generation of heat and the diamond side quickly removes substances.
