Desenvolvimento de protótipo para dispositivo extraoral impresso tridimencionalmente para avaliar a abertura bucal de pacientes

Abstract

Facial fractures represent a field of concern for health professionals, since they frequently interfere with the performance of the stomatognathic system and, consequently, the viability of the functions performed, such as speech and chewing. The intrinsic conditions represented by mandibular tumors, and conditions such as ankylosis, osteomyelitis, osteoporosis, dysplasias, contribute to the occurrence of mandibular fractures. However, the main determinants of facial fractures are trauma. These can occur due to accidents due to external causes (traffic accidents, gun violence or fire). The use of 3D technologies, such as Additive Manufacturing / 3D Printing, arise, assisting professionals in the medical and dental area, both in planning, and execution of surgeries, as well as in the elaboration of devices that optimize the postoperative evaluation of patients during the rehabilitation period. The objective of the present study was to develop a personalized extra-oral device capable of measuring the oral opening of patients in the postoperative period of the Bucomaxillofacial complex. The study was carried out in LABTEC 3D, located in the NUTES / UEPB, was experimental laboratory type, where, from the CAD software modeling Rinhoceros, was built a prototype of the extraoral device, which was modeled, improved and printed three-dimensional in FDM, in the high resolution mode, and it is ready for use in postoperative patients of Bucomaxillofacial complex surgeries.
