An obturator is a prosthesis that closes congenital or acquired defects in the palate. It functions to enable speech, mastication, improve esthetics, keep the defective area clean, reshape the palatal contour, and reduce exudate flow into the mouth. Obturators are classified based on whether the defect is congenital or acquired, and can include variants like inflatable bulbs or magnets. The case report details the 14 step process for fabricating a custom obturator to restore functions and improve the patient's quality of life.
