Description

Orthodontic pliers Technical Field The utility model relates to the technical field of orthodontic treatment, in particular to an orthodontic clamp. Background In the orthodontic fine adjustment stage, it is often necessary to add a vertical or horizontal step curvature to a single or multiple teeth to achieve good occlusion and alignment. At present, the common adjustment mode is that firstly, a ligature ring (wire) is removed, a stainless steel arch wire where a target tooth is positioned is marked by a marker pen in a mouth, then the arch wire is taken out, a corresponding step is bent outside the mouth by a thin wire bending clamp, finally, the arch wire is placed into a groove, and ligature fixing is carried out again. However, these steps are complicated, and the orthodontist must bend the step curve using a thin wire bending forceps outside the mouth, which requires a lot of time and affects the clinical efficiency. Disclosure of utility model The utility model aims to provide an orthodontic clamp which is used for solving the defects and shortcomings existing in the prior art. In order to achieve the above object, the present utility model provides an orthodontic pliers comprising: a clamp handle; The forceps beak is connected with the forceps handle, the forceps beak is provided with a pair of opposite clamping surfaces, the pair of clamping surfaces are used for clamping the orthodontic archwire, and the pair of clamping surfaces are provided with a matched step structure, so that the orthodontic archwire is bent to form a step curve. According to the orthodontic pliers provided by the utility model, the clamping surface at least comprises: The first clamping surface, the second clamping surface and the third clamping surface which are sequentially connected in a bending mode are formed to form the step structure, and a transition fillet is arranged at the joint of the first clamping surface and the second clamping surface and the joint of the second clamping surface and the third clamping surface. According to the present utility model, there is provided an orthodontic pliers comprising: The pair of the first orthodontic pliers and the second orthodontic pliers are arranged in pairs, and the step structure of the first orthodontic pliers and the step structure of the second orthodontic pliers are arranged in a mirror symmetry mode.
