Expanders

Fixed maxillary and mandibular expanders include a broad range of appliance designs. The designs are used to correct cross-bites, narrow arches and crowding. The fixed expanders utilize some mechanism of force (expansion screws, self-activating wire or wire activation) for development of the arch. Fixed appliances require minimal patient compliance and provide the doctor with better control during active orthodontic treatment. Auxiliary attachments such as brackets and habit breakers can be incorporated in most expansion appliances. See Custom Options
