Maxillary defects occur either as a result of surgical resection of malignant tumors of the nasal cavity and paranasal sinuses or of the congenital causes. Rehabilitation of the patients with maxillectomy defects presents a challenge in restoring the lost form, function and speech. Maxillary interim obturators in prosthetic reconstruction of the defects are often complicated with lack of adequate retention, stability, and support. This case report presents the simplified approach, to rehabilitate a case of sub-total maxillectomy due to squamous cell carcinoma of maxillary sinus, using a closed hollow bulb obturator prosthesis fabricated with a "U" loop and a modified buccal flange for enhanced retention of the prosthesis.
