Ameloblastoma is an odontogenic tumor that affects the bones of the jaw, often affecting posterior region of the mandible. It is a benign neoplasm and is fre­quently associated to an unerupted tooth. The purpose of this article is to report a case of failure in making an immediate full denture in a patient that had an ameloblastoma. A female patient aged 67 years complained of a hard swelling in the right mandible at the premolar region, that she noted after teeth extraction and confection of an immediate denture. Intraoral examination showed buccal and lingual cortical plate expansion and radiograph examination showed multilocular radiolucency with a well-defined margin. Fine needle aspiration was nonproductive and the provisional diagnosis was ameloblastoma. An incisional biopsy was performed and the histopathological report was conclusive of an acanthomatous ameloblastoma. The patient was sent for surgical excision of the lesion and after three years, the patient returned reporting that she was operated elsewhere in the past year and had an unsuccessful bone graft. She was sent to a prosthodontist to make a complete denture. In the present case the ameloblastoma was diagnosed only after the teeth extraction and immediate denture. KeywordsAmeloblastoma; Diagnosis; Mandibular neoplasms; Odontogenic tumors.
