Description

Pressure mode movable appliance

Technical Field

The utility model relates to a pressing-mode movable appliance.

Background

Because natural tooth volume and bone quantity are not adjusted, the orthodontic appliance is not worn on time to cause relapse after orthodontic treatment, and gaps between the rings are left after the orthodontic fixing appliance is detached, which are the reasons of scattered gaps in dentition. The scattered dentition in the gap not only affects the beauty, but also easily causes food impaction to cause local periodontal tissue inflammation and destruction. Meanwhile, due to the mechanical stimulation of the impaction and the colonization of bacteria, besides gingivitis and periodontitis, gingival recession, gingival papillitis, adjacent caries, alveolar bone absorption, halitosis and the like can be caused, and meanwhile, the existing pathological changes of periodontal tissues can be aggravated. When the above factors are found, it is necessary to remove as much as possible the plaque retention factors that may lead to the development of the disease. This helps maintain the functionality and aesthetics of the dentition.

The gaps of the bands refer to the gaps left on the proximal and distal surfaces of the molar after the orthodontic treatment is finished and the bands are removed. The band gaps may become progressively smaller in children's cases as the second molars or the third molars erupt, and in adult cases, the band gaps may be more likely to exist for life. In the research of von willebrand, the size of the gap between the adjacent surface and the ring of the proximal and distal teeth in the correcting system is 0.442 +/-0.0992 mm; the size of the gap between two adjacent belt loops is 0.842 +/-0.2101 mm.

In the orthodontic process, the use of the metal band ring is very common, and compared with a buccal tube, the metal band ring has the remarkable advantages of good retention and the like. Wanchengwei et al report that the falling rate of the molar bonding buccal tube is obviously higher than that of the molar band ring, and the band ring gap can be closed by removing the band ring and replacing the buccal tube and other methods in the later stage of orthodontic treatment. However, this approach can significantly increase the duration of treatment and patient satisfaction.

When the retainer is not worn and the patient is scattered in gaps in orthodontic treatment, an orthodontist can choose to perform fixed correction again, a great deal of time and energy are needed, the comfort of the patient is obviously reduced, and the invisible correction is too expensive.
