Basic prebonder
Fine sandblasting unit with an additional function for surface conditioning of restorations prior to adhesive cementation
Advantages
- Processing reliability in adhesive bonding thanks to standardized sandblasting of zirconium oxide and other materials.
- Reliable results thanks to scientifically defined sandblasting parameters and coordinated system components.
- Better control over a sensitive procedure by means of reproducible sandblasting conditions.
Details
- Consistent energy input via the Basic prebonder control tip for a defined working distance.
- Uniform surface roughness achieved through the special Basic prebonder jet nozzle with a homogeneous sandblasting jet.
- Clear process control with precision manometer and marked working range.
- Even abrasive flow provided by the Renfert Venturi mixing chamber.
- Precise blasting pulses thanks to IS (Immediate Stop) system without bleed-off.
Notes regarding use
To ensure reproducible results, the use of Prebonder surface pro is mandatory. The specialized 50-µm aluminum oxide complements the sandblasting energy and nozzle geometry as part of the scientifically optimized Prebonder system. The Renfert abrasives Rolloblast and Cobra, available in various grit sizes, are suitable for all other sandblasting applications.
