Precision in sandblasting with the "Control tip" nozzle

The quality of adhesive bonding depends significantly on proper surface preparation. In daily practice, however, this critical step is still often performed based on intuition — carrying risks for bonding strength, material stability, and the long‑term success of restorations. With BASIC prebonder, Renfert is transforming sandblasting into a controlled, reproducible, and scientifically validated process for the very first time.

Especially for non‑etchable materials such as zirconium oxide, precisely defined parameters are essential. Pressure, particle size, and working distance have a direct impact on bonding strength. BASIC prebonder standardizes these factors, ensuring greater process reliability, more gentle treatment of materials, and a consistently reliably improved bonding. 

Renfert’s in‑depth blog article demonstrates how subjective “feel‑based” sandblasting becomes a science‑driven workflow. Readers learn why uncontrolled sandblasting can lead to problems, what role scientific studies play, and how BASIC prebonder was developed as a complete system solution — from validated technology to practical, real‑world application.
