Correct positioning of the plastic guides provides for the correct fit of the
headgear to the patient and its being held firmly in place.
Attachment of the tubes (fig. 1)
The hook of the tube is placed in one of the open holes on the inner side of
the plastic guide and angled downwards. Do not force it through the slot.
Lift the tube and without using force turn it forwards by 180°. Reverse this
procedure if the tube has to be replaced or its position changed.
Attachment of the J-hooks (REF 744-713-00)
Push the J-hook into the tube and attach one of the previously selected rubber
rings to the double hooks and to the far end of the tube.
Extraoral latex elastics, standard size = 9.5 mm/
Variations (fig. 2)
In the later stages of orthodontic treatment, only one pair of J-hooks in the
high pull position is needed. In this case, it is usually an advantage to remove
the lower part (the neck portion) of the headgear. For this, the plastic guide is
cut in half with side cutters and the vertical strap is also cut through behind
the head just below the horizontal strap. The cheek pads should then be slid
over the upper part of the guide and stapled in position. The
headgear will now look like a conventional high-pull appliance.
