Dual flask technique for fabrication of two-piece hollow bulb obturator in a microstomia patient: A neoteric approach

Abstract

Tumor resections or traumatic injuries necessitating maxillectomy will often result in defects that create a communication between the oral and nasal cavities accompanied by difficulty in deglutition, speech, and an unaesthetic appearance. It also affects psychological status of the patient. Fibrosis and post surgical contracture of tissues restricts mouth opening in patients who had undergone maxillectomy and radiotherapy. Fabrication of a two piece obturator prosthesis is beneficial in such cases. presents the fabrication of a two piece hollow bulb obturator using sectional impressions and dual flask technique in a completely edentulous hemi maxillectomy patient with microstomia.
