Abstract

The invention provides a mandibular molar advancement device, which relates to the field of orthodontic clinical instruments. The device comprises a first retaining plate attached to the buccal side of the mandibular second molar, a second retaining plate attached to the buccal side of the mandibular third molar, an L-shaped rod, and is arranged on the root of the second molar Square retaining tube, stainless steel square wire, push spring in compressed state and micro-implantation nail, the micro-implantation nail is set on the buccal side of the second molar; one end of the L-shaped rod is welded on the first and second solid On the positioning plate, the other end extends toward the root of the tooth and passes through the retaining tube. The stainless steel square wire passes through the push spring. One end of the stainless steel square wire is fixed on the retaining tube, and the other end is connected to the retaining tube. Sliding connection of micro implant nails. The invention not only can effectively move the mandibular second molars and third molars forward, but also only involves the posterior tooth area, avoiding the anterior tooth area which patients pay more and more attention to, and greatly improving the aesthetic appearance and comfort of the patient.

Description

technical field [0001] The invention relates to the field of orthodontic clinical instruments, in particular to a mandibular molar advancement device. Background technique [0002] The loss of mandibular first molars is relatively common in clinical practice. Although traditional restorative treatment can meet the needs of patients, it will also damage the patient's natural teeth, and the cost is high. With the development of orthodontic treatment technology, patients can choose to pull the ipsilateral mandibular second molars and advance the third molars to replace the missing first molars and advanced second molars. However, in traditional orthodontic treatment, it is often necessary to bond the entire dentition to the bracket, which greatly affects the aesthetics and comfort of the patient. Contents of the invention [0003] The purpose of the present invention is to provide a device for advancing the mandibular molars, which is suitable for pulling the mandibular firs...
