Mandibular fractures resulting from extraction of impacted third molars are rare and cause postoperative morbidity to the patient. This study aims to present a clinical case of a mandibular fracture that occurred after an impacted tooth had been removed. The 19-year-old female patient sought care with a history of pain during mastication. After anamnesis and clinical examination, the presence of a fracture in the region of left mandibular angle was observed. The patient underwent an open reduction and fracture osteosynthesis with fixation plates through an intraoral approach. After a follow-up of 2 years, there were no pain complaints and satisfactory aesthetic and functional results. In this context, the present case highlights the importance of surgical planning and a long-term follow-up in cases of fracture after extraction of third molars, even this complications being uncommon.
