Removable tooth-borne expansion (expansion plate) vs observation

Crossbite correction · Children and adults with a posterior crossbite, without a Class III skeletal relationship, cleft lip or palate (or both), or other…

Removable tooth-borne expansion (expansion plate) leads to higher crossbite correction compared with observation (no treatment) (high certainty).
