Basic Prebonder, 70-250 µm, 100-120 V - Renfert item number 29694250. Fine Sandblasting Unit with an additional function for surface conditioning of restorations prior to adhesive cementation. Renfert standardizes surface conditioning prior to adhesive cementation in dental offices with The Basic Prebonder system. Scientifically defined Sandblasting parameters and coordinated system components transform a procedure that was previously highly dependent on The user into a defined clinical process. Basic Prebonder provides clearly defined conditions for surface treatment of zirconium oxide, metal alloys, hybrid materials, and modern polymers prior to adhesive bonding. Based on Renfert’s proven Basic quattro is technology, Basic Prebonder offers a practical, modular system. Flexible tank options and an ergonomic handpiece make clinical surface conditioning simple and efficient, while allowing for many other Sandblasting applications (e.g., denture cleaning, cement removal).
