Q. Can I turn the HATCH REAMER at high speed if there are a lot of remaining bones?
A. If there is a lot of residual bone, high speed rotation may result in bone heateing. It's just a little slower, but 40rpm is enough, and most importantly, slow speed is because you can feel the cortical bone of the maxillary sinus, which you can't feel at high speed. In addition, if there are many residual bones, you can get many autologous bones by deleting 40rpm without any number of weeks.
