<p>PROBLEM TO BE SOLVED: To provide a dental arch correction device having the capability of keeping a front tooth group firmly communicated to a lateral tooth group with wire deflection prevented, and ensuring high mounting workability. SOLUTION: This device has a band 2 to be laid around one tooth T of a lateral tooth group, an external tube 3 secured to the band 2, a wire 5 secured to each tooth of a front tooth group as well as extended toward the lateral tooth group, an energization means for energizing the wire 5 toward the lateral tooth group and an internal tube 4 formed to be longer than the external tube 3 and slidably supported therein. In addition, the internal tube 4 has an inner diameter large enough to lead the wire 5, and is formed to be capable of fixing the wire 5 to the open end thereof.</p> |
