BIOTECNOLOGIA E PLANEJAMENTO DIGITAL NO MANEJO DE FRATURA MANDIBULAR COMINUTIVA – RELATO DE CASO

Biotechnology associated with digital planning has become of great scientific value in advanced methods of facial reconstructive technologies. The present study aimed to report a mandibular reconstruction where there was prior digital planning concomitant with the use of osteogenic materials seeking better functional, aesthetic and debilitating post-surgical results. Patient 41 years old, male, smoker, alcoholic, drug user attended the private clinic for treatment of mandibular fracture caused by a firearm projectile. In initial consultation, face tomography with 3D reconstruction was requested in order to facilitate condylar repositioning via dolphin imaging software, which made it possible to make a mandibular prototype. With the prototype, a previous frame of the reconstruction plate was made to facilitate its installation in the trans-surgical area. For this, submandibular access was used for reduction, reconstruction and fixation. 3D reconstruction mesh, Infuse rhBMP-2 and Bio-Oss were used. Post-surgical clinical and complementary exams revealed the reestablished occlusion and the repositioned condyle centered inside the articular fossa returning to its real anatomical position, resulting in the success of the treatment. Therefore, it is important to highlight the influence and the constant need to update dental surgeons regarding the use of new reconstructive techniques in order to achieve the best prognosis for the patient.
