Easy-to-adjust orthodontic device

Abstract

The invention discloses an easy-to-adjust orthodontic device, which comprises an arch-shaped component; a fixing component which is used for being adhered to teeth of a patient; and an elastic piece which comprises a first connecting end, a middle section and a second connecting end which are connected in sequence, wherein the middle section is bent, the first connecting end is detachably connected with the fixing component, the second connecting end is detachably connected with the arch-shaped component, and at least two connecting gears are arranged on at least one of the arch-shaped component, the fixing component, the first connecting end and the second connecting end. According to the orthodontic device provided by the invention, the adjustment of orthodontic force, tooth movement displacement and the like can be realized by directly replacing the connecting gears, elastic pieces with different thicknesses do not need to be replaced, the production cost of the orthodontic device is saved, the operation duration of a doctor can be reduced by half by switching the connecting gears than replacing the elastic pieces, and the reception efficiency of doctors is improved.

Description

technical field [0001] The invention relates to the technical field of orthodontic instruments, in particular to an orthodontic device. Background technique [0002] At present, orthodontists use orthodontic instruments to treat patients with dental or facial problems such as crowded teeth, buck teeth, misaligned teeth, and malocclusion. Orthodontic appliances such as brackets and buccal tubes are orthodontic appliances. The main components of therapeutic equipment. In conventional orthodontic treatment, the orthodontist sticks the brackets on the patient's teeth, and puts the archwire into the archwire groove of the bracket, and the archwire exerts a corrective force on the teeth through the bracket to move the teeth to the correct position. Location. Orthodontic appliances are usually made of metal, and sticking to the teeth affects the appearance, so some patients choose to stick orthodontic appliances on the lingual side of the teeth for the sake of beauty during treat...

Problems solved by technology

The reason why the arch wire needs to be replaced in this way is because the teeth have not been aligned at the initial stage of correction, and the square arch wire is placed directly on it. On the one hand, the square arch wire is difficult to bend at a large angle and cannot be installed. On the other hand, because the square arch wire can realize the alignment of the teeth Torque adjustment, and during the torque adjustment process, the tooth root bears a large force, which may easily cause tooth root absorption. From the perspective of safety, square archwires cannot be directly installed

In the patent application CN109069229A, the elastic parts corresponding to each tooth position are used to replace the arch wire in the traditional orthodontic device. Because the structure of the elastic part is different from that of the arch wire, it has some curved parts, so it can be directly made into a square shape. Torque adjustment, but in order to ensure safety, it is still necessary to adjust the correction force of the elastic member according to the actual situation in the correction process, and the method adopted in the patent application CN109069229A is to design according to the situation first, and then customize the production of the elastic member. That is to say, multiple elastic parts are produced during the whole treatment process to adjust the correction force. With this solution, it is necessary to carry out separate mold production for the elastic parts at each stage, and the production cost is high. In addition, the adjustment process needs to change the elastic parts from the correction After the device is removed, a new one is reinstalled. For the doctor, the operation is more complicated, and for the patient, the diagnosis and treatment process takes a long time

[0004] Some patients have a certain tooth that needs to be moved with a large displacement, and it needs to be moved step by step. When the orthodontic device in CN109069229A needs to adjust the moving position, it is adjusted by replacing the elastic parts, and the number of elastic parts increases first. The production cost of elastic parts, and the process of replacing elastic parts is more complicated, which increases the doctor's diagnosis and treatment time
