Work on all-ceramic restorations

Grinding of ceramic abutments, trepanation or fitting of all ceramic restorations constitute a real everyday challenge for the dentist. Comprehensive test series were carried out and as a result, we offer a special ZR abrasive with diamond grain, which is perfectly adapted to these special requirements. The solution is a special bond, which bonds the diamond grains durably so that these abrasive instruments feature a considerably longer operating life and material reduction compared to conventional diamond instruments.
Different grains are available to suit the respective indications. Trepanation of all-ceramic restorations is preferably carried out with the instruments with coarse grain (green/white ring).
When fitting the dental prosthesis, it is recommended to use finer instruments with medium (blue/white ring) or fine grain (red/ white ring). The special ZR Komet abrasives are perfectly made for precise work on all ceramic restorations and are sure to become an invaluable aid in every dental practice.

  • Special coating for durable bonding of the diamond grain
  • Effective substance removal
  • Very long operating life
  • Shapes adapted to practice requirement

Polishing of all ceramic restorations - Introduction for use

1. Slight adaptation of the allceramic crown with the ZR862.314.016
2. Quick trepanation with the special round diamond ZR6801.314.010/014
3.‒5. For separating allceramic crowns, we recommend Jack (aka 4ZRS). As with tungsten carbide crown cutters, apply the instrument at an angle of 45° to the crown surface to achieve best results.

Polishing of all ceramic restorationsApart from the axial wall, the 1 2 3 4 5 incisal edge and, in case of molar and premolars, the occlusal surface should also be cut. This applies in particular to adhesive all-ceramic restorations.
To remove the restoration, this has to be widened until it fractures. This can be done with a lever or Planert crown widening pliers (DP 788R Aesculap Dental, Tuttlingen).

To grind down residual fragments, we recommend the 4ZR.314.012/014.

Recommendations for use

Efficiency of the ZR abrasives

• Optimal speed:
(160.000 rpm)
• It is recommended to use the instruments in the red contra-angle, as the higher torque is advantageous for efficient work on all-ceramic restorations (compared to the torque of a conventional turbine).Polishing of all ceramic restorations
• Use maximum spray coolant, especially during the trepanation procedure (min. 50 ml/min.).
• Apply low contact pressure (<2N).
