Abstract

This report is a case of 38-year old female patient who had a chief complaint about having pronounciation disorder after going under mass excision due to mucoepidermoid carcinoma. She was referred to department of prosthodontics, Yonsei university. Palatal lift prosthesis was fabricated which was then relined with tissue conditioner. Evaluations on phonetics and swallowing were done and improvements were shown. Tissue conditioner was replaced with heat polymerizing resin and the patient was satisfied with the results of treatment.
