BACKGROUND AND AIM: Maxillofacial defects due to malignant or benign tumors or congenital defects often result in complications such as the impairment of facial aesthetic, mastication, speech, and swallowing. Remedy of these defects, especially in a dentate patient is an important challenge in prosthodontics. Maxillectomy can lead to severe anatomical changes following tumor resection and reconstruction such as decreasing skeletal soft tissue support. The present study describes an implant-supported obturator in a dentate patient. CASE REPORT: The present study indicates an obturator prosthesis in a ۵۸-year-old patient with hemimaxillectomy (Aramany’s Class ۱ defect) undergoing the treatment of mucoepidermoid carcinoma of the right palate. The research describes clinical and laboratory procedures in rehabilitation of a dentate patient with tooth, tissues, and implant-supported obturator. CONCLUSION: In dentate patients, the maxillectomy requires careful planning for removable partial denture (RPD) framework design to achieve the best retention and soft tissue supporting. The patient was satisfied with her prosthesis in the mean aesthetic, phonetic, and swallowing aspects.
