Information for the doctor / patient
Before the palex®appliance is cemented into position, turn the spindle (screw)
slightly 2–3 quarter turns in the direction of the arrow to test the function.
Then turn back to the original position.
Turn the palex®screw only in the direction of the arrow. Opening and closing
the screw several times during the treatment can cause its malfunction. The
finished palex®appliance is cemented into position in the usual manner. Please
observe the instructions from the cement manufacturer.
Following this, the screw is turned four times by 90° using the blue
safety key (REF 611-120-00) for this purpose. One full 360° turn of the
spindle = 0.8 mm expansion.
The patient should turn the screw two times by 90° both in the morning and
evening (according to your instructions) until the desired expansion is achieved.
#
Important: Use only the blue safety key supplied, as this cannot accidentally
be swallowed.
Regular visits are recommended to monitor progress.
The palex®appliance is secured against unwanted turning-back, after the
desired degree of expansion is achieved, by fitting a ligature or blocking
with acrylic. For stabilization the appliance should remain in the mouth for
approximately 2–3 months.
A retainer should be worn following removal of the palex®appliance.
The product should not be used, if there is a known allergic reaction
to one or more of the material components.

2. General product description
The palex®screw (Palatal Expansion Screw) is a special screw for rapid palatal
expansion. The retention legs of the palatal expansion screw are welded onto
preformed metal bands or cap splints. Alternatively, they can be polymerized
into acrylic splints. The bands or splints are cemented in the usual way. Please
observe the instructions from the cement manufacturer.
3. Area of application
Used for rapid palatal expansion with a fixed appliance.
4. Fabricating a palex®appliance using the example of preformed
bands
Preformed bands are fitted on the maxillary left and right 1st bicuspids
and left and right 1st molars. These bands are transferred to a dental stone
model using an impression or fitted to a dental stone model. The legs of the
palex®screw are then bent to fit the bands so that they can be welded into
place (Fig. 1).

Safety key
REF 611-120-00
To prevent the legs from breaking during bending, we recommend using our
universal bending tool (REF 611-122-00, Fig.4). If one is not available,hold the
legs against the body of the expansion screw, using strong flat pliers (Fig. 5).
The palex®screw should „float“ freely at least 1–2 mm above the palate
roof/gingiva (Fig. 2). Its posterior side should form a straight line with the
mesio palatal cusps of the 1st molars.To avoid any leverage effect, it should be
ensured that the occlusal level is parallel.
5. Information on use of palex®screws
To increase strength, the bands can be joined on the buccal and/or lingual side
with a piece of 1.0 mm remaloy®wire (REF 528-100-00). Laser weld these
wires above the legs. The palatal strengthening wire should project slightly
beyond the bands and be supported by the adjacent teeth to allow better
distribution of expansion forces.
Easy, problem-free bending of the retention legs of palex®screws with the
universal bending tool (REF 611-122-00), without the use of additional pliers
(leverage principle).
To prevent the legs from breaking during bending, they should be held against
the body of the expansion screw using strong flat pliers e.g. Maxi wire-bending
pliers (REF 013-522-00).
When using the soldering technique please protect the body of the screw
against excessive heat, e.g. with heat screen (REF 380-070-00).
