Functional jaw orthopedics is a branch of dentistry that aims to prevent and treat abnormalities by directly affecting the muscle-nerve system that controls the growth and development of the jawbone. This involves monitoring growth and development, educating the patient and their parents, and treating deviations when they occur. Collaboration with other specialists such as an ear-nose-throat doctor or speech therapist may be necessary. The process requires cooperation, collaboration and trust between the child, the parents, and the dentist and can take a long time to achieve a balanced permanent bite. The treatment can also be applied to adult patients with the aim of restoring proper function.
