Management of regional sinistra palatal defects accompanied by partial loss of upper jaw teeth after Hemimaxillectomy using hollow obturators

Defects in the maxillary can occur due to birth abnormalities, growth disorders, trauma, and surgery. Patients affected by malignant tumor abnormalities in the upper jaw can have surgery to remove the tumor. The surgery will cause defects that will affect the function of chewing, articulation, and breathing. A rehabilitative treatment that can be done to close the defect after surgery is the creation of an obturator prosthesis. The purpose of making obturator prostheses is to restore speech, chewing, and respiratory functions. A good obturator prosthesis is a prosthesis that has good retention and stability, and has a light weight. The manufacture of obturator prostheses is expected to restore the quality of life and confidence of patients.
