On clinical examination, the patient presented with severely resorbed edentulous jaws, with an anterior marginal mandibular resection (Fig. 1a, b). The vestibular sulcus of the mandible was obliterated anteriorly (Fig. 1b). A radiographic evaluation of the maxillary and mandibular jaws, using the digital panoramic view (Planmeca ProMax, Finland), showed features of hypocellularity. (Fig. 1c).
