Why Leaf Expander®

The palatal expansion appliance series for a compliance-free therapy

Complete control of the maxillary expansion thanks to the predetermined, calibrated and constant forces released by the nickel-titanium MEMORIA® Leaf Springs.

Thanks to the unique characteristics of these expanders, daily home re-activation of the expander is not necessary. Leaf Expander® reactivation is performed by a clinician according to the suggested protocol, while the Leaf Self-activated Expander® model does not require re-activation either at home or by a clinician.

Prof.ssa Valentina Lanteri

Associate Professor in Orthodontics | UNIMORE University Modena and Reggio Emilia, Italy

I use the Leaf Expander® successfully whenever I need to solve a transversal discrepancy in young and adult patients. The nickel-titanium springs deliver calibrated and continuous forces allowing a predictable and pain-free expansion. In addition, since I don't have to rely on the parents' cooperation I have drastically reduced the number of control visits, optimizing my chair time to the mutual benefit of my clinic and the parents' schedules.
