Description
Technical Field
The utility model belongs to the auxiliary device is rescued to the tooth, and concretely designs an elastic push rod suitable for ware is rescued in stealthy nothing support groove.
Background
In the orthodontic correction process, the relative positions of the upper and lower teeth are improved by an elastic rubber band intermaxillary traction mode. In the bracket-free invisible orthodontic system, the common mode of inter-jaw traction is to reserve a space on an appliance (a transparent plastic tooth socket), bond a metal tongue button on the tooth surface, or pre-design a traction hook on the appliance. The bonded metal button can only act on a single tooth, the control force is weakened due to the reduction of the wrapping of the appliance, and the risk of the falling of the button in traction exists. The traction between the jaws is carried out by the preformed traction hook on the bracket-free invisible appliance, so that the closing dislocation force is applied to the appliance, the close fit between the appliance and dentition is influenced, and the sleeve can be separated when the appliance is serious, so that the treatment effect is influenced.
