Reconstrução de defeitos mandibulares usando reforço de placa dupla

Abstract

Objective: to report the case of a patient who presented a mandibular bone defect and had the area reconstructed with a double reinforcement plate superimposed. Case report: a 38-year-old female patient initially presented a condensing lesion that involved the entire mandibular angle region as well as the adjacent mandibular ridge. She underwent a surgical procedure under general anesthesia for resection of the lesion and, consequently, placement of a reconstruction plate. After six months, in the control radiographs, it was possible to observe the plate fracture and she underwent a new surgery to replace the fractured plate. Four months after the second surgery, through the followup panoramic radiograph, a new fracture in the reconstruction plate was observed. Therefore, it was proposed to reinforce the fixation by placing a double overlapping plate. Conclusion: the overlapping double plate reinforcement technique can reduce the stress on the plates for load and interface cases, thus decreasing both the probability of fracture and the loosening of screws.
