Silicon carbide stones with a ceramic binder for the dental practice and dental laboratory
Dura-Green stones, Dura-Green Fine stones, and Dura-Green wheels are made of high-grade silicon carbide and are exceptional for fast contouring and finishing of porcelain, composite, precious alloys, and amalgam.
The extensive range of shapes in Dura-Green stones and Dura-Green wheels are excellent for producing the individual characteristics to the surface texture of front teeth with their vertical and horizontal structures, also, for contouring and finishing restorative work where modern filling materials have been used.
Dura-Green stones and Dura-Green wheels can be cleaned or customised to any individual shape with the Abrasives Dresser.
Indication
In the dental practice
Contouring and finishing of porcelain, composites, precious metal alloys, and amalgam
In the dental laboratory
Contouring and finishing porcelain, indirect composites and metals
Range of use
Suitable for the following materials:
porcelain, composite, precious alloys, and amalgam
Note
Because Dura-Green stones contain carbide, they are not suitable for contouring and finishing ceramic alloys.
- precision running
- vibration-free performance
- consistent cutting action
- binder matched exactly to the grinding particles
- long operating life
- optimal cutting output
