Guided bone regeneration in supernumerary surgery

Abstract

Introduction: During the extraction of supernumerary teeth, bone defects are generated that can be treated through guided bone regeneration, which is the therapy to promote the formation of new bone. Objective: To present a clinical case of guided bone regeneration in a bone defect created during supernumerary surgery. Case presentation: A 16.1-year-old female patient, as a periapical radiographic finding, an irregularly shaped radiopaque area was found circumscribed by a radiolucent halo at the apices of 11 and 21, for which panoramic and tomography was requested. A supernumerary tooth was observed in a horizontal and inverted position, close to the floor of the nasal cavity. The diagnosis was single, unilateral, impacted and inverted Mesiodens with incomplete root development. Surgery and guided bone regeneration were performed under general anesthesia. A full-thickness flap was raised using electrosurgery, odontosection through two cuts, dislocation and exodontia of the supernumerary and pericoronal sac, once clean, the homogeneous bone graft and continuous sutures were placed in the defect and indication of therapy antibiotic, analgesic and anti-inflammatory. At 10 days, the patient presented adequate healing. Radiographic follow-up at 3 months showed adequate bone density and adaptation of the graft to the adjacent bone. Conclusions: To carry out a thorough radiological study for the early location of supernumerary teeth. Guided bone regeneration serves as a proliferative stimulus for bone cells and represents an effective alternative for the reconstruction of defects.
