As a practical alternative to conventional dental prostheses, implantology is becoming widely accepted. Individual teeth can now be safely replaced using the entry level KaVo INTRAsurg 300. A unit for all surgical operations. Special 110V AC motor provides maximum power at very low speeds (as low as 11 RPM). Maximum torque (5.5 Ncm) is available in the speed range of 300 – 12000 rpm. As speed is increased beyond this range, torque is reduced, ensuring bone is protected. An acoustic signal can be set, as well, to establish a desired torque limit.
