[0032] Optionally, the distance between the retrocurve and the molar segment to be intruded is 0.5 mm to 1.5 mm.
[0033] Specifically, the round wire main arch wire forms a posterior bend at the end, which corresponds to the mesial side of the upper and lower first permanent molars or molar segments that need to be lowered on both sides, so that the effect of lowering the molars can be achieved. The middle section of the round wire main arch wire forms a relative bend compared with the posterior bend, so that the middle section of the round wire main arch wire can achieve an opening for the anterior teeth. The device can achieve lowering and opening of the upper and lower molars through two round wire main arch wires. Orthodontics reduces the difficulty of orthodontic surgery and optimizes the structure of orthodontic devices, more effectively controlling the cost of dental treatment.
[0034] Optionally, an elastic leather ring runs through two corresponding small circles at the upper and lower parts.
[0035] Specifically, a small loop is made at the position between the lateral incisor and the canine of the round wire main arch wire, which facilitates the connection and fixation of the elastic leather ring with the upper and lower mandibular round wire main arch wires, and also enables the device to form a uniform and continuous depressing force.
[0036] Optionally, the transmission appliance brackets are respectively bonded to the maxillary central incisor, the mandibular central incisor, the maxillary lateral incisor, the mandibular lateral incisor, the maxillary canine, the mandibular canine, the maxillary first permanent molar and the mandibular first permanent molar.
[0037] Specifically, in this method, after bonding the curved transmission appliance brackets, the arc-shaped maxillary round wire main arch wire is connected to all the transmission appliance brackets on the maxillary, the two small circles correspond to the space between the maxillary lateral incisors and canines on the left and right sides, the two posterior bends correspond to the mesial sides of the maxillary first permanent molars or molar segments that need to be depressed on both sides, and the two posterior bends correspond to the mesial sides of the molars or molar segments that need to be depressed on both sides, and the distance from the mesial sides of the molars or molar segments that need to be depressed is about 0.5 to 1.5 mm; then the arc-shaped mandibular round wire main arch wire is connected to the mandibular All the transmission appliance brackets are connected, the two small circles correspond to the left and right sides between the mandibular lateral incisors and canines, the two posterior curves correspond to the mesial sides of the mandibular first permanent molars or molar segments that need to be depressed on both sides, and the two posterior curves correspond to the mesial sides of the molars or molar segments that need to be depressed on both sides, and are about 0.5 to 1.5 mm away from the mesial sides of the molars or molar segments that need to be depressed; finally, a 2 to 8 ounce elastic leather ring is used to connect the bilateral upper and lower mandibular small circles, so as to form a uniform and continuous depression force on the molars with the posterior curves to correct the open
