Abstract
Patient: An 85-year-old male with edentulous jaw developed dysmasesis and dysphagia after ostectomy of the mandibular border for a tumor of the mouth floor and immediate reconstruction with the cervical flap. An implant-supported fixed prosthesis and a palatal augmentation prosthesis(PAP) were fitted in the mandible and maxillary, respectively.
Discussion: The anatomical form of the mandible was damaged by tumor resection and the lower lip turned towards the tongue; therefore, a fixed upper structure was used for the mandible. Maxillary PAP installation supported the oral stage of swallowing, which was disturbed by expansion of the oral cavity proper with an increased height of articulation. Sufficient contact pressure for swallowing was obtained between the tongue and palate.
Conclusion: A patient with edentulous jaw after resection of an oral-floor tumor showed improved masticatory and deglutitive functions after installation of an implant-supported fixed prosthesis in the mandible and a PAP in the maxillary.
