ABSTRACT:
An orthodontic method for moving maxillary teeth by spreading the midpalatal suture completely obviates the time-consuming procedure of securing the appliance to the teeth by means of orthodontic bands and brackets specially fitted around the teeth by directly bonding the appliance to lingual surface areas of the teeth. An improved maxillary expansion appliance includes a pair of U-shaped anchoring elements each having a plurality of mounting pads secured thereto which are adapted to be bonded by means of an adhesive directly to lingual surface areas of opposed maxillary teeth and form the sole points of contact between the appliance and the teeth, yet provide firm anchoring of the appliance to the teeth while significantly improving oral hygiene and eliminating the unsightly appearance of orthodontic frame work on the facial surfaces of the teeth visible when the lips are parted. The improved appliance includes shiftable structure for facilitating final fitting of the appliance to the teeth.
