O impacto da impressão 3D no auxílio de exodontias de terceiros molares mandibulares em um serviço de público de procedimentos de média complexidade

Abstract

This research aims to test, in practical situations, whether the use of 3D printed biomodels is advantageous in extractions of impacted mandibular third molars (3MMI) offered in an establishment that is part of the SUS. For this, 21 patients were selected from the flow of care at the third molar extraction outpatient clinic, maintained by the School of Dentistry of the Federal University of Uberlândia. Following an inclusion criterion, which specified the type of impacted and impacted teeth, the difference between groups was the use of cone-beam computed tomography imaging examination, considering the best indication for the case, and the printing of 3D biomodels. The 3D model was printed with an additive manufacturing process, after a segmentation and preparation process carried out in the Blender program. The analysis was carried out with the professionals who performed the procedures, gauging the differences in patient preparation, planning, communication, surgery time and anatomical orientation during the procedure. Communication with patients had the most significant impact of the use of biomodels. Other aspects did not demonstrate statistically significant results but demonstrated benefits that can be explored in new research and care. Thus, it is proven that there are advantages in the use of biomodels during the surgical act that justify the implementation of a digital flow for their availability to SUS users.
