From anatomic and functional aspects the stomatognathic system and the upper cervical spine are closely interlinked. Together with complex neuromuscular relationships, this gives rise to an important field of cooperation between orthodontics and orthopedics. The literature appeals for close interdisciplinary cooperation for patients with syndromes and for those with torticollis and scoliosis. Since orthopedic points of contact are obvious in these special cases, orthopedic aspects are now being taken increasingly into account in farther-reaching studies. With the rising popularity of manual medicine, these aspects are being recognized from the orthopedic point of view too in terms of functional correlations and are being increasingly debated at international congresses and in the literature. Although relevant publications were initially confined to studies of moderate scientific interest or case reports, potential correlations have undergone scientific investigation in recent interdisciplinary studies. Despite the many clinical studies, no unequivocal recommendation can be given for basic conditions under which an orthopedist is bound to be consulted on patients with orthodontic findings. This literature review is aimed at providing an introduction to this still hotly debated issue.
