Background: Osteomas are rare benign osteogenic tumors, most often occurring in the craniofacial region. Their slow growth and asymptomatic course frequently delay diagnosis until significant expansion is evident.

Case Presentation: We report the case of a 42-year-old male presenting with an indolent, hard swelling of the right maxillary alveolar process, evolving over 8 years. Clinical examination revealed a firm, sessile, well-circumscribed mass extending from the distal aspect of tooth 16 to the edentulous area of tooth 17, displacing tooth 18. Radiographic assessment demonstrated a homogeneous radiopaque lesion with trabecular patterns and well- defined margins, without root resorption. The lesion was surgically excised under local anesthesia via an intraoral approach, requiring the extraction of teeth 16 and 18. Gross examination showed two osseous fragments measuring 3.5 cm and 4 cm. Histopathological analysis confirmed the diagnosis of osteoma, with no signs of malignancy. Postoperative follow-up at 6 months revealed uneventful healing and no recurrence.

Conclusion: Although osteomas of the maxilla are exceptionally rare, they should be included in the differential diagnosis of maxillary radiopaque lesions. Complete surgical excision provides cure with excellent prognosis.
