Description
Technical Field
The utility model relates to the technical field of orthodontic appliances, in particular to a traction hook device for orthodontics.
Background
In orthodontic treatment, ideal tooth movement can be achieved only by ensuring sufficient and reasonable anchorage control, and particularly in the case of tooth extraction, the preparation and control of the anchorage are key problems affecting whether the treatment process is smooth and whether the treatment is successful. Generally, in orthodontic treatment, an anchorage part mainly comprises one or a group of anchorage teeth, and the anchorage teeth are subjected to the action of anchorage force which is the opposite direction force generated by the orthodontic force. The strong anchorage traction hook is usually used for connecting an anchorage tooth and an orthodontic tooth, so that the anchorage tooth provides orthodontic force for orthodontic tooth. However, the base of the traditional towing hook is fixedly connected with the groove hook, and in order to ensure that a constant anchorage force is provided in the process of correction, the anchorage tooth cannot be displaced relatively in the process of providing the anchorage force. If the orthodontic tooth is selected as the anchorage tooth, the anchorage tooth needs to be corrected after the traction hook is removed, such as twisting the tooth angle or the bucco-lingual torque, so that the correction period of the patient is increased.
Therefore, patent specification No. CN209864102U discloses a novel strong anchorage pull hook for orthodontics, which overcomes the disadvantage that the strong anchorage pull hook for orthodontics has too strong constraint on anchorage teeth, so that the anchorage teeth can be corrected while providing anchorage resistance, and the period of orthodontics is shortened. This novel just abnormal strong branch of tooth is resisted and is drawn hook, including base stock and groove hook, a groove hook of two base stock shares, the groove hook is located under the base stock, and the groove hook passes through the connecting rod and is connected with two base stock rotations. The base is connected with the anchorage tooth fixedly, the relative connecting rod of base has the rotational degree of freedom, and at the in-process of correcting the anchorage tooth, the rotation of anchorage tooth can not influence it and provide the anchorage force for correcting the tooth to can correct the anchorage tooth simultaneously and correct the tooth. The draw hook has the disadvantages that firstly, the position of the groove hook is fixed and can not be adjusted according to requirements; secondly, the length of the cross arm is fixed, and the height position of the base support cannot be adjusted according to the requirement.
