2. General product description / area of application
The Variety/Variety SP expansion screws are universal expansion screws that
can be used in the lower jaw to create space,control tipping of the anterior and
posterior teeth as well as to open and close spaces in both the upper and lower
jaw.They can also be used as distraction screws, or for early palatal expansion
of the upper jaw at the beginning of the mixed dentition phase. The dental
age should however not exceed 8 years. The Variety/Variety SP are welded to
preformed bands or cap splints using its retention legs and do not require the
use of acrylic. The bands / cap splints are then cemented into place as usual.
Follow the instructions from the cement manufacturer.

The smaller Variety Mini– 8 and the Variety SP (small palate) Mini – 8
expansion screws are provided with a longer guidance pin to prevent
the screw from coming apart once it has reached maximum
expansion. Variety Maxi– 12 and Variety SP (small palate) Maxi – 12
expansion screws do not have this safety feature!
3. Fabricating an appliance with a Variety/Variety SP expansion screw
Preformed bands are fitted on the mandibular left and right 1st bicuspids and
left and right 1st molars on a hard plaster model. The bands / cap splints are
adjusted to fit on a hard plaster model.The legs of the Variety/Variety SP screw
are then bent to fit the four bands/ cap splints so that they can be welded
into place (Fig. 3).
The Variety /Variety SP screw should “float“ freely 1–2 mm above the gingiva
(Fig. 4).To avoid any leverage effect, please be sure the direction of force runs
parallel to the occlusal plane.
4. Tips for working with Variety /Variety SP expansion screws
In order to bend the retention legs of the Variety /Variety SP screw gently and
easily, we recommend using the universal bending key (REF 611-122-00,
Fig. 5) without the aid of pliers (lever principle). If this is not available, the
retention legs must be stabilized by holding the expansion screw body with a
pair of sturdy pliers, e.g. wire bending pliers Maxi (REF013-522-00), in order
to prevent the retention legs from breaking (Fig. 6).
When using the soldering technique please protect the body of the screw
against excessive heat, e.g. with heat screen (REF380-070-00).

Information for the doctor / patient
Before the Variety/Variety SP appliance is cemented into position, open the
spindle (screw) by making 2– 3 quarter turns in the direction of the arrow to
test the function. Then turn back to the original position.
Turn the Variety /Variety SP screws only in the direction of the arrow. Opening
and closing the screw several times during treatment can cause it to loosen and
no longer function properly.
The finishedVariety/Variety SP appliance is cemented into position in the usual
manner. Follow 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: Always use the blue safety key supplied to avoid accidental
swallowing.
Regular visits are recommended to monitor progress.
The Variety/Variety SP appliance is secured against unwanted reversing,
after the desired degree of expansion is achieved, by fitting a ligature
or blocking with acrylic. The appliance should remain in the mouth for
approximately 2– 3 months for stabilization purposes.
A retainer should be worn following removal of theVariety/Variety SP appliance.
The product should not be used if there is a known allergic reaction to
one or more of the material components.
