Prosthetic rehabilitation is a major concern for the post-maxillectomy patient, because maxillectomy results in communication between the oral and nasal cavities, which leads to dysfunction of speech, mastication and swallowing. Key factors for achieving optimal functional recovery after surgery are retention and stability of the obturator prostheses; however, their quality is greatly influenced by the patient’s remaining teeth, residual ridge and the size of the defect. Support, bracing and retention of obturator prostheses are relatively easily achieved using the remaining teeth in partially edentulous patients. However, for edentulous patients with extensive maxillary defects, functional recovery is challenging due to the poor retention and stability of their obturator prosthesis. Even in some partially edentulous cases in which maxillary reconstruction is undertaken to counteract the stability of the obturator prosthesis, functional recovery is a difficult task. Here I describe several typical cases of prosthetic rehabilitation of patients with extensive maxillary defects and complex maxillary reconstruction.
