Basic prebonder XS Renfert – compact microblaster for surface conditioning prior to adhesive cementation
The Basic prebonder XS Renfert is a compact single-tank microblaster designed to standardise surface conditioning before adhesive cementation.
It enables the preparation of zirconia, metal alloys, hybrid materials and modern polymers under defined conditions, using low and controlled blasting pressure.
With its XS format, precision pressure gauge, Prebonder control tip, Prebonder jet-nozzle and Prebonder control pad, it provides a simple and reproducible solution suited to dental practices and laboratories already equipped with a blasting cabinet or dedicated blasting box.

Low pressure Bonding microblasting from 0.6 to 1 bar
Complete system Nozzle, tip, control pad and abrasive included
A compact system to standardise blasting before bonding
The Basic prebonder XS has been designed to transform a sensitive, technique-dependent step into a more controlled process: surface conditioning prior to adhesive bonding.
Unlike conventional blasting focused on material removal, the Prebonder system aims for controlled surface activation, using specifically coordinated components: defined working pressure, special nozzle, spacer tip, qualified abrasive and visual control of blasting energy.
Its compact design allows easy integration into an existing workstation, together with a blasting cabinet, blasting box or suitable extraction area.
The clinical and technical need
Before adhesive cementation, the quality of surface pretreatment directly influences the consistency of the bonding protocol.
Overly aggressive blasting may adversely affect the material structure or surface wettability, while insufficient blasting may reduce the activation required for adhesion.
The challenge is therefore to obtain appropriate, repeatable and controlled blasting energy, especially on modern materials such as zirconia, alloys, hybrids or polymers.
The Basic prebonder XS solution
The Basic prebonder XS Renfert combines low microblasting pressure, a dedicated nozzle, a spacer tip and power control via a control pad.
This system helps the user maintain a defined working distance, control the impacted area and quickly check blasting energy before treating the restoration.
The intended result is a more standardised, clearer and more reproducible conditioning process.
Main applications
Zirconia pretreatment
Conditioning of zirconium oxide before bonding or adhesive cementation protocols.
Metal alloys
Controlled activation of metal surfaces before bonding, repair or prosthetic assembly.
Hybrid materials
Preparation of modern hybrid materials requiring controlled blasting energy.
Modern polymers
Conditioning of polymer surfaces within a defined pre-bonding protocol.
Benefits for the dental practice or laboratory
- Standardised process for conditioning before adhesive cementation.
- Compact format that is easy to integrate into an existing workstation.
- Low working pressure suited to bonding microblasting.
- Integrated spacer tip to help control the working distance.
- Special Prebonder nozzle for more homogeneous surface activation.
- Control pad for quickly checking blasting power before use.
An approach focused on reproducibility
The Basic prebonder XS does more than project an abrasive: it is part of a system designed to control several critical parameters.
Pressure, working distance, nozzle geometry, abrasive and blasting energy control all contribute to securing a sensitive step in the adhesive protocol.
Key components of the Prebonder XS system
Prebonder control tip
Spacer tip designed to help maintain a defined working distance between the nozzle and the restoration surface.
Prebonder jet-nozzle
Special nozzle developed for homogeneous abrasive projection and consistent surface activation.
Precision pressure gauge
Clear display with working range allowing blasting to be adjusted within the recommended zone.
Prebonder control pad
Control pad used to quickly check jet energy before treating the restoration.
Recommended Prebonder surface pro 50 µm
The Basic prebonder XS system is designed to operate with Prebonder surface pro 50 µm abrasive.
This high-purity aluminium oxide completes the Prebonder system: particle size, geometry, hardness, purity, pressure and nozzle are designed to work together.
- 50 µm aluminium oxide.
- Dedicated abrasive for the Prebonder system.
- Recommended use for reproducible results.
- Compatible with the Basic prebonder XS abrasive chamber designed for this abrasive.
Why avoid non-dedicated abrasives?
Abrasives with a similar stated particle size may differ in shape, hardness, purity or blasting behaviour.
To preserve the logic of the Prebonder protocol, it is recommended to use the consumable designed for the system.

Protocol implementation
The procedure is performed with pressure set within the range suitable for bonding microblasting.
The pressure gauge allows pressure control, while the handpiece must be used inside a blasting cabinet, blasting box or suitable extraction area in order to contain the abrasive.
- Set the pressure within the recommended working range.
- Place the handpiece inside the cabinet or dedicated box.
- Use the control pad to check jet energy.
- Maintain a stable distance using the control tip.
- Treat only the relevant areas of the restoration.
Power control with the control pad
The Prebonder control pad allows a quick check that blasting energy is correctly adjusted before working on the restoration.
This step helps secure the protocol and limit variations linked to pressure settings or working distance.
- Quick check before use.
- Visual reading by colour change.
- Assists adjustment of blasting energy.
- Practical support for a reproducible process.
Care and maintenance
To preserve the performance of the Basic prebonder XS, the unit must be maintained regularly and disconnected from compressed air before any cleaning or maintenance operation.
- Regularly check the tank and lid.
- Clean the exterior with care.
- Avoid cleaning agents containing solvents.
- Check the water separator and drain condensate if necessary.
- Monitor the condition of the nozzle and wear parts.
Points requiring attention
Moist abrasive or impurities can disrupt dosing and cause blockages.
Cleaning the dosing nozzle and checking the filter cartridge are among the operations to plan according to the use of the unit.
- Use a clean and suitable abrasive.
- Do not expose plastic parts to solvents.
- Check components subject to wear.
- Refer to the Renfert maintenance document for detailed procedures.
