This report describes a simplified method for construction of an interim hollow bulb obturator for an acquired maxillary defect. Final impression was made with irreversible hydrocolloid and the master cast was blocked out with plaster. Wax up was done leaving thc hollow bulb open after acrylization, the defect was filled with table salt and selfcure resin was used to cover the defect. Later a small hole was made and the table salt was washed off in water and the hole was also filled with self cure resin, The obturator was well retained in the patient's mouth and markedly improved his ability to speak and swallow-This technique proved to be a simple, quick, and cost-effective method for construction ofhollcw bulb Obturators for acquired maxillary defects.
