Double-wire straight wire arch correction device and tooth correcting method

Abstract

The invention belongs to the technical field of tooth orthodontics and in particular relates to a double-wire straight wire arch correction device and a tooth correcting method. The device consists of a bottom plate and a double-wire arch supporting groove which is fixedly connected to the bottom plate, wherein a main groove and an auxiliary groove which are parallel to each other are formed on the double-wire arch supporting groove; the main groove is positioned on a combined side of the teeth and is a square groove; and the auxiliary groove is positioned on the root side of the teeth and has the same width and depth as those of the main groove, and the bottom of the auxiliary groove is arc-shaped. The tooth correcting method comprises the following steps of: aligning and leveling the teeth in the main groove by using a titanium-nickel round wire at the initial stage of the correction; using a stainless steel round wire in the main groove after the teeth are aligned in the main groove, controlling the root of the teeth in the auxiliary groove by using the titanium-nickel round wire, namely aligning the root of the teeth; and closing the gap by independently using a stainless steel square wire in the main groove after the root of the teeth is controlled. The root control correction force can be obviously reduced, the risk of absorbing the root of the teeth in the correcting process is reduced, the process of bending the clinical arch wire can be simplified, the treatment defect brought by error of the bent arch wire is overcome, and the double-wire straight wire arch correction device and the tooth correcting method can be applied to tooth extraction cases.

Description

technical field [0001] The invention belongs to the technical field of orthodontics, and in particular relates to a double-wire straight wire arch orthodontic device and a tooth orthodontic method for treating malocclusion. Background technique [0002] Root resorption is one of the common complications of orthodontic treatment. Orthodontic root resorption is an inevitable phenomenon accompanying orthodontic treatment. Since the incidence of root resorption after orthodontic treatment is as high as 20%-80%, it has become an urgent problem to be solved. . The root cause of root resorption in orthodontic treatment is related to the excessive concentration of apical stress during orthodontic treatment. It is currently recognized that the root tip of the tooth receives the greatest stress during root control (torque) movement. The traditional straight wire arch correction technology needs to use a thicker square wire for root control. Excessive correction force during root cont...
