i-expander

The i-expander is a simple, removable device that can be used for steady transverse expansion of either arch and overcomes a lot of design problems that traditional removable expanders incur. It is made from high strength, pressure-formed polycarbonate and comes standard with a surgical grade stainless steel expansion screw (titanium screw optional). The i-expander utilises a clasp-less design as the polycarbonate shell covers the posterior teeth, just over the gingival margin, giving the appliance superior retention in the mouth and making it very comfortable for the patient. This covering of the teeth and also lingual areas of the anterior teeth stops super eruption of the arch and of the opposing arch.
