Prebonder surface pro

Abrasive for surface conditioning prior to final cementation

The highly specialized abrasive Prebonder surface pro was developed for the final cementation of restorations. Clinical surface conditioning through focused sandblasting ensures a reliable final bond on zirconium oxide, metal alloys, hybrid materials, and modern polymers. The 50 μm aluminum oxide (Al₂O₃), with defined grain size distribution, particle shape, hardness, and purity, creates — together with the Basic prebonder and coordinated parameters — the ideal micromechanical retention for durable bonding.

Advantages

• Scientifically validated: Optimized through extensive in-vitro studies for maximum bond strength in final cementation.
• Reproducible results: Precisely defined grain geometry, material hardness, and purity for consistently high surface quality.
• Gentle on materials: Focused surface transformation for ideal micromechanical retention without aggressive processing or loss of flexural strength.
