AbstractMaxillary obturator prosthesis is more frequent modality of treatment than surgical reconstruction for maxillectomy in patients suffering from oral defects. It is a standard practice to hollow out the defect portion of the obturators to reduce its weight. The processing technique described in this case report involves incorporation of the"customised glycerine soap bolus with cold cure stabilizing rod" during packing procedure of the obturator prosthesis and eliminated later once the curing procedure was completed. This technique is a single step procedure resulting in the closed-hollow obturator as single unit with uniform wall thickness around the hollow space ensuring the least possible weight of the hollow obturator.
