ABSTRACT
PURPOSE: This study was aimed to evaluate the effect of implant drilling speed on the composition of particle size of collected bone debris. METHODS: Branemark System (R)drills were used to collect bone debris from 10 drilling holes (1 unit) at 1,500 rpm (Group A) and 800 rpm (Group B) in bovine mandible. After separating particles by size into > 500 microm, between 250 microm and 500 microm, and 500 microm fractions, Group B had significantly higher wet volume % (P = 0.0059) and dry volume % (P = 0.0272) than in Group A. CONCLUSIONS: The drilling speed influenced the composition of particle size in collected drilling bone debris. The drilling in 800 rpm produced the more percentage of large particles than in 1,500 rpm. However, the drilling speed didn't effect on total volume of and weight of bone debris.
