Abstract
In connection with implant work on the dentine, a machining instrument is used which is provided with an attachment part for attachment to a rotary unit or for attachment to extension unit, which in turn can be applied to the rotary unit. The extension unit has a thickened central section which is provided with a recess or opening in which an inclined surface is arranged. In the applied position of a machining instrument, one surface of its attachment part is set against the inclined surface of the extension unit. The extension unit and the machining instrument are rotationally-fixed with respect to each other. 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.
