The round aluminum table rotated at 20 rpm (clinical measured average turns with the rotating device around the implant). Samples of the Tigran™ PeriBrush™—before and after use—and dental implants with sandblasted- acid-etched titanium surfaces before and after the treatment with rinsing were investigated by scan- ning electron microscopy (SEM) after different loads/forces and treatment time. The load/force of 20 g/0.2 N for 60 seconds is the suggested and rec- ommended normal treatment case and 60 g/0.6 N for120secondsoftreatmenttime,asthisload/force is the suggested worst case scenario. SEM analysis confirmed the gentle polishing ef- fect to the implant surface with all loads/forces in thisstudy.Loads/forcesofmorethan60g/0.6Nand 120secoftreatmenttime(worstcase)resultsinmi- nor damage to the brush—caused by an uncon- trolled vibration with a “slip-off” of the brush thus bending,butnotrupturingthefinetitaniumbristles (Figs. 12–14).
