ORTHOBITES Fig. 1 Fig. 2 Fig. 3 vated nitanium helical coils to distalize the molars. Metal wires are laser weld from the molar bands to the Rapid Palatal Expander component. The purpose of this is to negate the distalization until you have corrected the crossbite. After you have created the expansion as Fig. 6 depicts, you then simply cut the metal wires and let the pre-activated coils distalize the molars. Also note the rests on the upper primary molars. It is important to employ flowable composite over these onto the occlusal surfaces to secure them to the teeth. The expansion took three months for full correc-tion. In May 2010, the wires were cut and Fig. 7 shows the distalization which then occurred. Again this was a duration of three months.
