ORTHO BITES Fig. 22 Fig. 26 and palatal shelves to drop down as the primary teeth and molars move out of cross bite. Figs. 24 and 25 show the progress and success with the appliance to correct the cross bite. To prevent a potential relapse of the corrected cross bite, the NPE (serving as a palatal bar) was left in for a minimum of eight months. The finger springs were removed from the appli-ance, crimpable posts on the utility arch wires were placed and the patient was instructed to wear one 1/4 inch light (2.5 oz. force) per side to maintain the Class I molar relationship (Fig. 26). Fig. 27 shows the completion of Phase I. A bonded 1-1 was placed on the upper and a lower fixed removable lingual arch on the lower (Fig. 28). The fullness was diminished and the parents were very pleased with the results (Fig. 29). They were instructed to bring their daugh-ter in every six months for regular cleanings and an evaluation of the eruption of the permanent canines and premolars. It was discussed that the baby teeth might need early removal. At that time it will be determined if there is any need for Phase II.
