<![CDATA[Ossifying fibroma (OF) is a slow-growing benign tumour derived from undifferentiated cells of the periodontal ligament. The seg-mental resection surgical procedure involving the maxilla in tumour removal surgery causes oronasal defects in breathing, swal-lowing and phonetics, in addition to the patient's psychological state. Rehabilitation of the defect using an obturator prosthesis allows the patient to regain the affected functions. An obturator prosthesis is a plate that closes an intraoral defect and can be clas-sified into surgical, interim and definitive obturators. This article reported the prosthetic rehabilitation of a post-hemaxillectomy defect in an OF patient in stages. A 19-year-old female was referred to the Prosthodontics Clinic of the Oral Surgery Clinic for the fabrication of a surgical obturator that was placed immediately post-hemaxillectomy. After three months, the patient was rehabilita-ted with an interim obturator. Final rehabilitation was done seven months later with a definitive metal-framed obturator to restore chewing, breathing, phonetic and aesthetic functions which resulted in improved quality of life for the patient post-hemaxillectomy.]]>
