Gnathological treatment is a specialisation within dentistry. The dentist examines the occlusion of the upper and lower jaws, that is, the fitting of the upper and lower teeth against each other and how the joints and muscles of the jaws are functioning.
Gnathological treatments are often required in case of temporomandibular joint complaints (e.g. myoarthropathy / Costen's syndrome etc.) and in complex prosthodontics.
The movements of the lower jaw (in relation to the cranium) are registered and the models resulting from the dental imprints can be reproducibly fixed in an apparatus (articulator), so that the jaw movements can be simulated.
