Leone Rapid Micro Expander Screw for Lower

The new micro-expanders, available in 8 and 11 mm models, feature a slim design unmatched by other rapid expanders. These unique devices have 2 extra-long arms, allowing for the possibility of anterior support and ensuring excellent stability and maximum comfort in any configuration. The expander can be placed in the standard position, with a laser-marked arrow and max-expansion length visible to the user, or in the upside down position, indicated by 2 laser-marked arrows, in order to reduce the space occupied by the expander arms if the jaw is especially narrow. The A0621 screws can also be used to obtain dental expansion in the lower jaw. Every package contains 1 screw,1 hinged key (A0558-00) and 1 direct key (A0557-00) for laboratory use.
