摘要：
An orthodontic remodeling device includes a sleeve having first and second screw holes in two ends thereof. The first and second screw holes have opposite thread directions. A first screw rod includes a first threaded portion threadedly engaged with the first screw hole and a first assembling portion exposed outside of the sleeve. A second screw hole includes a second threaded portion threadedly engaged with the second screw hole and a second assembling portion exposed outside of the sleeve. Two tooth pushing members are respectively engaged with the first and second assembling portions. Each tooth pushing member includes at least one tooth coupling ring mounted on at least one tooth of a patient for pushing the at least one tooth outward. The sleeve is rotatable to move the first and second screw rods toward or away from each other to change a relative position between the two tooth pushing members.
