Length of treatment · Children and adults with a posterior crossbite, without a Class III skeletal relationship, cleft lip or palate (or both), or other…
Fixed tooth-borne expansion (quad-helix) probably leads to lower length of treatment compared with removable tooth-borne expansion (expansion plate) (moderate certainty).
