Tool for drilling bone tissue, particularly suitable for performing a sinus lift according to the summers technique or for the fitting of extra-short implants
A tool for drilling bone tissue, which has the advantage of having a cutting tip with a flat effective shape that prevents perforation of the Schneider membrane or injury to the dental nerve when drilling close to them. The tool is disposed along an longitudinal axis and includes a non-cutting main body, a narrowed area for retaining bone and a cutting tip, which includes cutting blades, each one of which is provided with a front cutting edge substantially perpendicular to the longitudinal axis and a substantially lateral cutting edge that forms an angle of between 0 and 10° with the longitudinal axis. Spaces for receiving bone are disposed between the cutting blades and are connected to the narrowed area.
