Oral cancers are often diagnosed at advanced stages and usually require surgical removal of the tumor and surrounding tissues, often followed by radiotherapy and chemotherapy. Surgery involving the palate and maxillary sinus can create an oro-nasal communication that affects swallowing, speech, and drinking, causing significant physical and emotional distress. Prosthodontic rehabilitation therefore plays an essential role in restoring function and improving quality of life.Rehabilitation of acquired maxillary defects is complex due to limited supporting tissues, tooth loss affecting retention, impaired healing, and ongoing tissue changes. Management typically occurs in three stages: a surgical obturator placed immediately after surgery, an interim obturator provided within 3-4 weeks during healing, and a definitive obturator fabricated after 6-12 months once tissues stabilize. Advances in imaging, biomaterials, implants, bone grafting, microvascular reconstruction, and hyperbaric oxygen therapy have greatly improved rehabilitation outcomes.
