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.

Extraction.
All three have their place but nowadays, e...
