Rapid Palatal Expander 13mm

The Morelli Rapid Palatal Expander is a Hyrax-type palatal expansion screw indicated for correcting deficient maxillomandibular relationships. Built entirely in stainless steel and driven by a central screw, this model provides a 13 mm expansion range, matched to the transverse discrepancy of the case.Key Features 13 mm expansion range — supplied as one individual screw. Hyrax central-screw design — activation is applied to a single central body, keeping the expansion vector symmetrical. Flexible arms — adapt to different palatal morphologies during appliance assembly. Stainless steel construction — high resistance to the repeated loads of a rapid expansion protocol. Smooth, controlled activation — the screw advances progressively for predictable transverse movement. Long-stem activation key included — 100 mm stem, allowing the screw to be activated safely and conveniently.
