摘要： There is disclosed a torque control unit to be used with an instrument for implant surgery, a drilling system including the control unit, and a method for controlling torque with the control unit. The control unit includes a torque limiter (5) that is detachably attached to the bur (4) of the instrument for presetting and shuts off torque transmission from the bur (4) at a preset torque value, and a control section (3) controlling current value of the driving section (2) of the instrument. The control section (3) includes a detector (331) for detecting a current value of the driving section (2) corresponding to the preset torque value when the torque limiter (5) shuts off torque transmission, a memory (332) for storing the detected current value, and a current controller (333) for controlling a current value of the driving section (2) in accordance with the stored current value.

摘要： A dental handpiece (1) is disclosed for injecting an air-powder mixture and water against teeth for dental treatment. The handpiece (1) includes a container (10) for accommodating powders, an air supply line (22) for supplying air into the container (10) to produce an air-powder mixture in the container, a mixture transfer line (17, 51) for transferring the mixture, a water supply line (16, 53) for transferring water, and an injection nozzle (33, 40) for injecting the mixture and the water against a treatment site. The container (10) has a curved inner surface for allowing whirl of air spatially in all directions in the container. The air supply line (22) has a plurality of branched lines (22a, 22b) each extending in the central part of the container to close proximity to the curved inner surface of the container (10). Each of the branched lines (22a, 22b) has in its distal part a plurality of ports (23a, 23b) oriented to direct air flow therethrough along the curved inner surface of the container.
