Orthodontics and Myofunctional Therapy: A critical review of the best complementary treatments of orofacial dysfunctions (Part 1).

AIM: This critical review article illustrates the anatomo-physiological complexity of the orofacial district that makes orthodontic and myofunctional therapies naturally complementary. METHODS: The evolution of the face and mouth's structures and functions intimately connects not just bones and muscles but several functions: breathing, sucking, swallowing, chewing, biting, protective mechanisms such as spitting or coughing, and parafunctions such as clenching or nocturnal bruxism. These functions (among others) are mediated by an extremely complex neural system that involves, affects, or is affected by relevant cranial nerves, the sensory-motor system, the sympathetic and parasympathetic systems, the enteric system, and the breathing system. CONCLUSION: This interdisciplinary approach promotes the lasting success of orthodontic treatment and supports overall body wellbeing.
