The presence of a large palatal or maxillary defect after partial or total maxillectomy for tumor,trauma or congenital deformation poses a challenge to prosthodontists,particularly when the use of an implant cannot be considered. This case report described the use of an air valve in a hollow silicone obturator to manufacture an inflatable obturator that could be extended further into undercut area to retain itself. The inflatable obturator exhibited adequate retention,stability and border sealing,thereby improving the masticatory,pronunciation and swallowing functions of patients. It may be a suitable alternative treatment option to an implant-retained obturator.
