Preservation of remaining structures is a primary goal of prosthetic rehabilitation. Continuously applied stresses on the remaining tissues froma large, heavy obturator jeopardize the health of the tissues, compromise the function of the prosthesis and affect patient comfort. Varioustechniques have been described for hollowing the bulb of an obturator after processing to reduce its weight; however, access to the inneraspects of the bulb is limited, preventing adequate control of thickness of the walls. This article presents a case report of a partially edentulouspatient after partial hemimaxillectomy successfully rehabilitated with closed hollow bulb obturator prosthesis. The weight of the obturator hasalways been a hurdle in the rehabilitation of acquired palatal defects. A simple procedure for the fabrication of one piece hollow bulb obturatorhas been described in this article.
