“…A stable record base is critical for recording an accurate maxillomandibular relationship and in evaluation of the esthetics and phonetics of the wax trial prosthesis. The fit and stability of the record base for an obturator however is often compromised because of the size of the surgical defect and is further compounded by the need to block out undercuts and by the under extended borders [7][8]. A processed record base provides maximum support, retention and stability for a maxillofacial prosthetic patient and additional steps of relining the record base can be avoided.…”

The acquired defects of the palate are created commonly surgical intervention of benign or malignant neoplasms. The size and location of the defect influence the level of difficulty in prosthetic rehabilitation. Surgical intervention creates anatomic defect which forms communication among the oral cavity, nasal cavity and maxillary sinus. The goal of prosthodontist is to rehabilitate missing oral and extra oral structures with restoration of normal anatomic and physiologic function. Prosthetic rehabilitation with obturator restores the oral structures and also acts as barriers between communications among the cavities.

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 describes a double-processing technique for an obturator to optimize the weight and thickness of the bulb.
