Description

Double jaw dental arch linkage appliance Technical Field The utility model relates to an orthodontic appliance, in particular to a double-jaw dental arch linkage appliance. Background The anterior teeth in teenager's malocclusion deformity has higher proportion of anterior teeth malocclusion, functional malocclusion and osseous malocclusion, and particularly the later is an malocclusion deformity with great difficulty in orthodontic clinical correction, and the orthodontic is usually treated by a movable hyperbolic tongue appliance, an FR-3 functional appliance or an anterior traction appliance in clinic. Patent No. ZL 2016 20007.236.2 discloses a maxillary dental arch advancing appliance, which consists of a part of a device of the upper jaw and the lower jaw, wherein the upper jaw is a 4-hook Nance holder, namely, a thick wire traction hook (welded together with a belt loop) is arranged on the palate side of a first molar belt loop by utilizing a front rubber support connecting wire, and the left side and the right side of the appliance are respectively provided with a traction hook attached to a molar belt loop buccal surface tube.
