Molar distalization correcting device

Abstract

The invention relates to the technical field of orthodontics, and discloses a molar distalization correcting device. The molar distalization correcting device comprises an implanting nail, a main body rod, at least two push rods and a traction piece, wherein the implanting nail is punched into the jaw bone of a patient, the push rods are assembled on the main body rod, clamping grooves for clamping arch wires are formed in the push rods, a traction hook is arranged on the side, away from the implanting nail, of the main body rod, one end of the traction piece made of an elastic material is hung on the traction hook, and the other end of the traction piece is hung on the implanting nail. According to the molar distalization correcting device, pulling force for completing molar distalization is creatively changed into pushing force, so the application scope of the molar distalization correcting device is greatly enlarged, good correction effect can be achieved on teeth deep in the oral cavity, and correction efficiency is improved; and the traction hook is arranged in the anterior tooth area or the canine tooth area, so operation of medical staff is facilitated, and use experience is good.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to a molar remote-moving orthodontic device. Background technique [0002] Orthodontics usually refers to the treatment process of correcting irregular tooth arrangement, abnormal tooth shape and abnormal tooth color through oral technology. Among them, in orthodontic treatment, for complex cases of dento-maxillofacial deformities, doctors often need to move the molars distally to provide a basis for aligning interdental spaces, leveling the dentition, and adjusting the occlusal relationship. In order to avoid the displacement of normal teeth when molars are moved distally, tiny implant screws are generally implanted in the jawbone to provide absolute anchorage, and at the same time, a traction device is bonded to the distally moved teeth to move the teeth with the implant screws to achieve orthodontic treatment. However, the above method is less effective for the teeth locate...

Problems solved by technology

In order to avoid the displacement of normal teeth when molars are moved distally, tiny implant screws are generally implanted in the jawbone to provide absolute anchorage, and at the same time, a traction device is bonded to the distally moved teeth to move the teeth with the implant screws to achieve orthodontic treatment. However, the above method is less effective for the teeth located in the deep part of the oral cavity. At this time, the teeth are close to the implant nails, and the traction distance of the implant nails is limited. Orthodontic device for molar displacement
