Cavity Preparation | S-Diamonds®

The opening of the cavity and the initial preparation are noticeably simplified with the help of these structured diamond instruments. The use of S-Diamonds is highly recommended for increased efficiency. Their particular advantages make structured diamond instruments especially suitable for a gentle treatment.

Advantages:

The combination of a structured blank and coarse grit allows quick and effective substance removal and improved cooling

The faceted structure of the blank reduces clogging and consequently the generation of heat

The operation becomes notably more effective

The time saved during treatment is equally beneficial to you and your patient

In order to prevent the formation of micro cracks, it is recommended to use instruments with rounded edges (to be recognised by the letters KR in the figure number).
