Palatal defects cause multiple problems in speech, mastication, esthetics, and maintenance of oral hygiene. Obturators help in normal deglutition, prevent nasal regurgitation and normal speech production. The fabrication of obturators has been done by various methods in the past using different materials that are incorporated to make hollow bulb, such as modeling wax, sugar, dental stone, and putty. Difficulties have been experienced in removal of these incorporated materials. It is difficult to maintain the form of the hollow bulb and to maintain position of incorporated material as well as the thickness of the heat-cure resin during acrylization. The effect of heat during acrylization is different for different materials. Thus, the final form of the obturator, ease of removal of the incorporated material, and maintenance of hygiene postinsertion are dependent on the material chosen for incorporation in the hollow bulb. This case report describes a novel material for fabrication of a hollow bulb obturator. The fabrication is single stage and easy for the operator.
