DURABILITY OF OSCILLATING BONE SAW BLADES

The purpose of this study was to measure the durability of disposable saw blades using a standard bone-cutting experimental model that can b e replicated in any laboratory. Using a constant cutting force, the bo ne-cutting efficiency was determined by recording the maximum cutting temperature and the rate of material removal. In this experimental stu dy, porcine femurs as well as a synthetic bone substitute were used as the test samples for measuring cutting efficiency. Repeated cutting o f these test materials did not significantly alter the performance of the disposable bone-cutting blades.
