Interdisciplinarity is an integral part of orthodontics. In older orthodontic textbooks, we read about cooperating with ear, nose and throat specialists when dealing with young patients with impaired nasal breathing, about speech therapy and myofunctional therapy, and about orthopaedic connections to posture.

There are also many reports on pre-prosthetic orthodontics. For many years, we have been writing and teaching about cooperation between aesthetic dentistry and orthodontics.
