This device is an evolution in the design of the previous spring-loaded expander, designed with technical and scientific collaboration of Dr. Claudio Lanteri
and Mr. Filippo Francolini. This new expander features a small size body, and
it is equipped with two Nickel Titanium MEMORIA® leaf springs allowing
the release of calibrated and continuous forces to promote the expansion of
the maxillary arch. Re-loading is needed when the two opposing leaf springs
move apart: the endoral activation, which must be done in the dental office,
will put the springs in contact again thus allowing the release of the selected
force. The expander is available in two models, 450 g and 900 g and each
one of these is available in two expansion capacities: 6 mm and 9 mm. The
expander is supplied with the leaf springs (2 or 3 according to the size) readycompressed by two metal staples that the technician will remove after the
construction of the device.
The package includes a special clip with safety leash to keep the leaf springs
compressed, facilitating the technician and the clinician in specific phases of
the realization and treatment. Inside the package are also available practical
instructions for use where all the construction steps and methods of delivery
to the clinician are illustrated.
Supplied with a swivel key with handle to facilitate the endoral activation by
the professonal.
