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
