Orthodontic appliances are broadly classified into two categories: fixed and removable. Fixed appliances are more effective in treating most types of orthodontic problems, while removable appliances can be taken out by the patient. Functional orthodontic appliances are based on the idea that form and function are directly dependent on each other. The Forsus fatigue-resistant device is an alternative to a helmet that helps to eliminate excessive overbites, improve the fit of the teeth, and possibly avoid the need for jaw surgery.
It works by gently pulling the teeth to restrict the growth of the upper teeth and jaw forward. The palatine expander is used to widen the upper jaw by exerting gentle pressure on the upper molars every time an adjustment is made. Positioners are used to complete the final movements of the teeth in orthodontic treatment, and retainers are used to keep the teeth in their new and correct positions after treatment. Transparent orthodontic wires are being studied for application in general orthodontic patients, while transparent removable aligners are a recent advancement in orthodontic treatment for adults and adolescents.
The activator is a typical functional orthodontic appliance used to treat displaced occlusal positions. Orthodontic treatment with braces requires a constant and cooperative effort from both the orthodontist and patient. Patients should not chew on hard objects, such as pencils or nails, as they can damage appliances. Orthodontists should ensure that the patient's bones, gums, and tooth roots are in good condition before applying braces.
The general dentist can identify a malocclusion and refer patients to specialists, such as orthodontists. Orthodontists have a wide range of options for selecting an orthodontic appliance for a particular application. Herbst appliance is an orthodontic appliance that actively guides the growth and development of the jaw.
