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).
