A MARPE appliance (Miniscrew-Assisted Rapid Palatal Expansion) is an advanced, non-surgical orthodontic solution designed to gently widen the upper jaw in teens and adults by stimulating the palatal suture. Using four small titanium anchors placed in the roof of the mouth, MARPE provides effective expansion without the need for surgical procedures like SARPE. This approach helps correct narrow arches, relieve crowding, improve crossbites, and can even support better breathing.
