Functional braces are designed to improve the way your teeth bite together. They come in many forms, from Twin block braces to Bionator braces to fixed-functional braces.
Functional braces can correct abnormal bites relatively quickly. How they work so quickly is a matter of debate among orthodontists – but evidence suggests it is because of the way that they can move the teeth, with a small influence on the growth of the jaws.
For best results, a functional brace is usually followed by a fixed brace to help perfect the position of your teeth.
