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