Fixed appliance

What does the term „fixed appliance” mean?

Fixed appliances are special devices that are composed of various hooks (braces and rings) fixed on the teeth using special kinds of glue. Because fixed appliances exert force on the teeth non-stop for the whole duration of treatment, their use makes it possible to achieve detailed treatment outcomes. According to treatment needs and esthetic requirements, various types of braces may be indicated:

  • Metal– cheaper, they make it possible to change the appearance by the use of colour elastic bands that are used to fix the archwire.
  • Esthetic – ceramic, they are tooth-coloured, i.e. they are less visible


How to care for teeth when wearing braces?

Maintaining appropriate oral hygiene while wearing braces is extremely important. It protects the teeth from caries formation and demineralisation, and may make the treatment shorter. A basic rule is to brush the teeth after each meal. It can be made easier by using special interdental toothbrushes that reach all spaces. Moreover, dental floss and antibacterial fluoride-containing mouthrinses should be used. Irrigator is a helpful device.

What does the term „retention” mean?

It is the last stage of orthodontic treatment performed after removing fixed appliances. It denotes stabilising corrected occlusion and new positioning of teeth. This stage is necessary because collagen fibres of the periodontal ligament –i.e. the tissue that holds the teeth in the bone – require 12 months to become stable after the appliance is removed.
retention appliances –i.e. retainers – can be removable (a transparent splint) or fixed (a thin wire glued to the internal Surface of front teeth). Duration time of retention depends on the Patient’s age, the severity of malocclusion, treatment method, maxillary and mandibular growth direction.

If the retainer has become loose or does not fit, please contact the orthodontist as soon as possible. Do not try to repair the retainer on your own as it may influence the position of teeth negatively.
