OLIVERA OLIVA, A et al. Late mandibular fracture after lower third molar extraction: a case report. Av Odontoestomatol [online]. 2019, vol.35, n.3, pp.107-112.  Epub 18-Maio-2020. ISSN 2340-3152.  https://dx.doi.org/10.4321/s0213-12852019000300002.

The lower third molar extraction is a common procedure in oral surgery. One of its complications, although uncommon, is the mandibular fracture. Postoperatively, it has an incidence lower than 0.005%. The factors that may contribute to the risk of the mandibular angle fracture after an extraction of the third molar include the level of impaction are the anatomy of the tooth, previous local infections, age, sex, cysts and bruxism among others. We present a clinical case of postoperative mandibular fracture at five weeks after the extraction of 47 and 48 included in horizontal position. The ultimate treatment goal of a mandibular fracture is to reach a bone consolidation with the premorbid dental occlusion. In our case, as it was not a fracture that surpassed the cortical and there was not a mandibular displacement, it was not need a surgical treatment so it was resolved with functional rest.
