COUTINHO, Tatiana Albuquerque et al. Adaptations on the stomatognathic system of individuals with maxillomandibular disproportion: literature review. Rev. soc. bras. fonoaudiol. [online]. 2009, vol.14, n.2, pp.275-279. ISSN 1982-0232.  http://dx.doi.org/10.1590/S1516-80342009000200021.

This research had the aim to identify adaptations on the stomatognathic system of individuals with maxillomandibular disproportions. The literature review was carried out using national and international databases, addressing adaptations on the stomatognathic system of subjects with maxillomandibular disproportions submitted to orthognathic surgery associated to speech-language intervention. It was found that subjects with prognathism and retrognathism present adaptations in all oral-motor functions during the presurgical period. In mandibular prognathism, the most adapted function is mastication, which is characterized by vertical movements using the dorsum of the tongue for kneading the food, and less use of the masticatory muscles. In mandibular retrognathism, studies showed that deglutition is most adapted, being characterized by anterior mandibular slide, in addition to postero-anterior movement of the tongue and perioral muscles activation. After orthognathic surgery, some cases may present adequacy of the stomatognathic system functions. In other, however, adaptations may persist, making it necessary that speech-language therapists are well informed about pre-existent adaptations, in order to plan the best rehabilitation process for each case.
