Purpose: The aim of this study was to compare the bone collection capacity of bur drill systems used in implant surgery with different diameters, lengths, and drilling speeds.
Materials and methods: This study was performed on bovine ribs. Two bur drill systems were studied: Implantium (Dentium) and Straumann (Institut Straumann). The groups were divided into subgroups according to the bur diameter. As a result, there were four Implantium subgroups (3.3, 3.8, 4.3, and 4.8 mm) and three Straumann subgroups (3.3, 4.1, and 4.8 mm). In addition, for each bur diameter, the bone collection capacities of the drill systems were evaluated at three different drilling speeds (150, 250, and 400 rpm) and two bur lengths (10 and 12 mm). The diameter, length, and speed changes were performed, and the results were compared between the two drill systems.
Results: The mean bone weight collected by using the Straumann burs was higher than that of the Implantium burs at each drilling speed and bur length. Using the Straumann system, the different drilling speeds/lengths of the burs had no impact on the bone collection capacity, irrespective of the bur diameter (P > .05). However, the drilling speeds/lengths of the Implantium system resulted in a statistically significant difference in the same diameters (P < .05).
Conclusion: Both bur systems were suitable for autogenous graft collection for bone grafting in implant surgery, but the Straumann burs were more successful than the Implantium burs.
