leoneamerica_leaf-self-expanderLeoneAmerica Dental Products Inc, Oxnard, Calif, introduced the Leaf Self Expander—a new type of expansion device for orthodontic patients.

According to the company, the Leaf Self Expander requires zero patient compliance and zero clinical activation. The expander, which features nickel titanium springs, uses the flexible properties of these springs to release predetermined, controlled, and continuous forces throughout treatment as the springs decompress.

The Leaf Self Expander is available as part of the Memoria Leaf Spring Series line, in either 6 mm or 9 mm, with a force selection of either 450 g or 900 g.
