What is a common term for orthodontic fixed appliances?

The common term for orthodontic fixed appliances is "braces." Braces consist of brackets, wires, and sometimes bands that work together to correct misaligned teeth and jaws. They are bonded directly to the teeth and remain in place throughout the treatment period, making them a fixed appliance.

Aligners, on the other hand, are removable orthodontic devices designed to gradually shift teeth into the desired position but are not classified as fixed appliances. Retainers are typically used after braces to maintain the position of teeth once they have been corrected, and expanders are devices used to widen the upper jaw. However, neither of the latter two is synonymous with the fixed appliances typically referred to as braces. This distinction highlights why braces is the appropriate term for fixed orthodontic appliances.
