Abstract

The treatment of Class II non-extraction cases, especially when premolar space is lost due to premature loss of the deciduous molars, usually requires distal movement of the maxillary molars. The Jones jig appliance is a non-compliant intraoral appliance and is effective for the distalization of the maxillary molars. It has unfavorable side-effects, however, so caution is needed to adjust the appliance and select appropriate cases. We reported four cases in which maxillary molar distalizations were concomitant with the alignment of palatally erupted premolars.
