Abstract

The bone particles collected during osteotomy could be used as autogenous bone graft materials for implant placement surgery. This study examined the effect of drill design on the quantity and size of bone collected during the preparation of implant sites. Bone was collected during the in vitro preparation of bovine bone using three different implant system drills: parallel shape (Group 1), tapered shape (Group 2), and tapered and stepped shape (Group 3). Bone particles were sieved. The wet volume and dry weight were measured. The mean total wet volume collected per osteotomy was 0.199 ± 0.0445 ml and the dry weight was 0.0477 ± 0.0087 g. In all three groups, bone particles >500 μm were harvested in larger amounts than particles 250–500 and <250 μm. Group 3 drills produced smaller bone particles than Group 1 and 2 drills. The size differences were significant when Group 3 particles were compared with the particles produced by Group 1 drills. The differences in total dry weight of bone collected by the three drilling systems were not statistically significant. Drill design significantly influenced the size of bone particles collected during the preparation of implant sites.
