Description

Dental correcting auxiliary device

Technical Field

The utility model belongs to the technical field of the tooth is rescued, more precisely relate to fixed dentistry and correct the technique, especially indicate a dentistry and correct auxiliary device.

Background

In the field of orthodontic treatment, fixed appliances commonly used include brackets, archwires, traction devices and other attachments. The support groove is directly stuck on the tooth surface by an adhesive, and the arch wire is clamped in the support groove, wherein the main function of the arch wire comprises: firstly, the tooth fixing device is used for fixing and guiding, and plays a role in controlling and guiding the movement of teeth; and the other is used as a force application device to generate correction force for correcting the teeth so that the teeth can move as required, wherein the force application mode can be generated by the restoration of the deformation of the teeth or by the traction of a traction hook. However, because the slot is in a structure that the lip and the cheek are horizontally opened, the daily activities (such as brushing teeth, eating and the like) of a patient can easily cause the arch wire to fall off from the bracket slot, so that the teeth do not complete the expected movement, and the correction fails.

Currently, there is a new dental device (for example, patent document CN212234739U) on the market, which uses a pipe provided on the body to pass through the arch wire and apply a correction force to the teeth to which the device is attached. The shape of the pipeline on the dental device and the shape of the arch wire are matched to be round or square, the size and the dimension of the arch wire are also standard sizes, a clinician selects the arch wire with the size and the shape most meeting the requirements from the standard arch wires according to the actual size of the dental arch of a patient, then the arch wire passes through the dental device pipelines which are stuck on teeth one by one, and the acting force of the arch wire on the dental device drives the teeth to move for correction. However, the dental device generally has a problem in the orthodontic process, a clinician spends more time and effort in the process of manually threading an arch wire in order to thread the arch wire through all the adhered and fixed pipelines, and also puts higher requirements on the clinical operating experience of the clinician, and as the operating time is long, the orthodontic experience of a patient is worsened, and the problem is more serious for dentition with serious crowding and malposition.
