摘要:
In connection with implant work on the dentine, use is made of a machining instrument which is provided with an attachment part (31) for attachment to a rotary unit. The machining instrument can alternatively be applied in an extension unit which in turn can be applied to the rotary unit in a corresponding manner to the machining instrument. The extension unit has a thickened central section (17c) which is provided with a recess or opening (24), in which an inclined surface (29) is arranged. In the applied position of a machining instrument, one surface (30) of its attachment part is set against the inclined surface (29). A rotationally-fixed cooperation is present between the extension unit and the machining instrument. Moreover, a locking effect is achieved between the extension unit and the machining instrument as a result of a secure wedging effect obtained by means of the inclined surface. The rotary movement transmitted from the rotary unit to the extension unit is in turn transmitted to the machining instrument, which moreover is secured in the longitudinal displacement direction.
