1. A method for controlling and/or regulating a compressed-gas-operable medical or dental drive device comprising a rotor and a tool-holding device connected to the rotor, wherein the drive device can be supplied with compressed gas at a maximum gas pressure from a compressed gas source to induce a rotational movement of the rotor and wherein the drive device comprises a valve for adjusting the gas pressure and/or a flow rate of the compressed gas,wherein the method comprises operating the rotor at a substantially constant rotational speed at least within a limited load range by adjusting the gas pressure and/or the flow rate of the compressed gas through the valve, andwherein the rotational speed is reduced on reaching a predetermined pressure value of the compressed gas, which is lower than the maximum gas pressure of the compressed gas.
