Facebow-hinge
The hinge is fitted to the inner bow of the side not to be distalized
and the outer bow on this side is shortened to the position in line
with the first molar. The outer bow of the side to be distalized
remains in the original length. It should be remembered that during
distal movement the molar could rotate in a palatal direction.
