Stomatognathic system is a part of the human body inϐluenced by external factors. Initially considered a relationship between occlusion and temporomandibular joint, it turned out to be a more complex morphological and functional unit, consisting of tissues and organs functionally combined with one another [8]. Apart from the temporomandibular joint, we have to stress the importance of the bones of the head, alveolar process, teeth, periodontium, neuromuscular system, blood and lymph vessels, oral mucosa and salivary glands, in the functioning of the stomatognathic system.
