Technical Field

The invention relates to the field of design and production of dental special orthodontic appliances and articles, in particular to a tooth space closer.

Background

After the dentition is damaged, the teeth on two sides of the edentulous area are displaced, and gaps exist among the teeth; gaps also often exist between the teeth of natural dentition. In the traditional method, gaps are closed through orthodontic treatment, brackets are directly bonded on teeth, the teeth are arranged and leveled through arch wires, and the gaps between the teeth are closed. The orthodontic treatment of the teeth by adopting the mode has the advantages of long orthodontic time, high cost, poor appearance and difficult oral hygiene. The invisible correction also has the problems that if the tooth space is not closed, food impaction occurs to the tooth after implantation and restoration, periodontitis, natural tooth decay or peri-implantitis is caused, and finally the implant fails.

In order to solve the above problems of the conventional orthodontic treatment, those skilled in the art have developed various orthodontic treatment methods for closing the tooth space generated after tooth extraction, such as chinese patent: a device (authorized notice number: CN206548619U) for closing maxillary tooth extraction gap adopts a palatal implant anchorage, and then uses a tension spring and an arch wire to pull and correct teeth, so that teeth at two sides of the edentulous position close the tooth gap.

The closing of the interdental space in the above manner has the following disadvantages:

1. this mode limitation is fairly obvious, can only carry out the clearance to the upper jaw and close, can't close the lower jaw dental space, because the lower jaw is the planting that can't carry out the anchorage, so, when carrying out the closure in lower jaw dental space, can only pull to lower jaw tooth single surface (being the surface) and pull the correction, and during unilateral single face operation, the flank appears easily because of the spring pulls and the lateral surface slope appears, makes the dental space close failure.

2. The mode not only implants anchorage and has the defects of high operation risk, high operation cost, slow postoperative recovery, failure of anchorage implant, foreign body sensation and the like, but also brings great operation pain to patients.

3. This mode carries out the tooth clearance and closes, and whole process not only need plant the operation, still need drag the correction and close, and whole process time is longer relatively, corrects the in-process moreover and also is inconvenient for going on to the adjustment of extension spring and arch wire, and the operation is comparatively inconvenient, and oral hygiene is difficult.
