Maxillary expansion is associated with varying degrees of pain and functional impairments. The current study aims to compare rapid maxillary expansion using a McNamara-type (bonded) appliance and slow maxillary expansion using a removable palatal expansion appliance concerning patient-centered outcomes. Those outcomes will include pain and discomfort, mastication difficulties, swallowing difficulties, and pressure on the soft tissues.
