The aim of this study was to report the clinical case of retained lower canine extraction associated with fixation of the reconstruction plate in the atrophic edentulous mandible, in a hospital environment. Female patient, 69 years old, presented to the service of the hospital center of the municipality of Santo André/SP complaining of “swelling in the chin”. Extraoral examination showed erythematous volumetric increase, painful on palpation and soft consistency in the submental region. On intraoral examination, there was a fistula without purulent drainage in the atrophic edentulous mandibular ridge near the area of tooth 43. The panoramic radiographic examination showed the retained tooth 43 extending from the uppermost portion of the alveolar process to the mandibular base. After planning, surgery was performed in a hospital environment under general anesthesia, through extraoral (submental) access for tooth extraction and 2.4 reconstruction plate (locking system) to prevent pathological mandibular fractures. Clinical and radiographic controls were performed at 7, 21, 30, 90 and, 180 days after surgery, there was no pain complaint, inflammation or infection. Thus, it suggests that extraction of the infected canine associated with the placement of reconstruction plaque was a viable and effective option for treating the retained tooth in the atrophic jaw and preventing fracture for mandibular atrophy, improving the clinical prognosis of the case.
