Fixed appliances are the most common type of orthodontic appliance. These are typically attached to the teeth with brackets and wires and are not removable. Fixed appliances are effective in moving teeth and aligning the jaw. 

Removable appliances are also used to treat malocclusions. These are typically used in milder cases or as an adjunct to fixed appliances. Removable appliances are generally made of plastic and can be taken out and cleaned. 

Functional appliances are used to correct the growth of the jaw. They are often used in growing children to guide the jaw to grow in the correct position. Common functional appliances include activators, functional retainers, and twin blocks.

Interceptive appliances are used to correct dental issues before they become more serious. These are typically used in younger children and can help guide teeth into the correct position. Interceptive appliances include space maintainers, lip and cheek bumpers, and palatal expanders.

Orthodontic appliances are an important part of orthodontic treatment. Each type of appliance has its own purpose and can be used to treat a variety of dental issues. It is important to consult with an orthodontist to determine which type of appliance is best for each particular case.
