Desenvolvimento tridimensional de dispositivo para a reabilitação fonoaudiológica pós cirurgia ortognática

Abstract

This dissertation aimed to develop an individual dynamic functional device for speech therapy rehabilitation of the Temporomandibular Joint (TMJ) after orthognathic surgical procedure, based on identification of the limitations of the devices available on the market. Thus, the study was conducted through knowledge about the intervention orthognathic, stomatognathic functions, speech therapy and rehabilitation of mandibular movements, extraoral devices and 3D technology. This research was developed in two stage the realization of an integrative review, based on the descriptive exploratory methodology, and in a second phase, the development of a dynamic functional device was proposed. A computarized tomography obtained in a private clinic of a randomly selected dental arch was used as a research instrument, as well as Autodesk® Inventor software and STL file, in which the modeling and product development was performed. The result of the integrative intervention research demonstrated, in studies compiled through practical intervention in individuals, that static devices are inefficient in carrying out lateralization movements that are fundamental for the proper performance of stomatognathic functions; in the second stage of the research it was possible to obtain as a result through the available models a dynamic device that allows the movements of mandibular lateralization. Therefore it was possible to infer that there was the possibility of making the device a low cost, which favor speech-language habilitation/rehabilitation after orthognathic surgery and subsequently, it was submitted a patent application.
