fan-type expansion screw
The fan type expansion screw exists in two designs: As a one piece or two piece expansion screw. Both have the same function, to expand the anterior or posterior region fan shaped. The two piece expansion screw has the advantage that through the separate fixation of the screw and hinge, the lever is longer so that the fan type expansion is enhanced.
