[The maxillofacial prosthesis: palatal obturators. The principles of treatment and rehabilitation in a case of buccorhinosinusal communication].

Having analysed the causes which lead to the loss of substance from the palatal vault, the different types of communication which then result, their evolution and the consequent functional defects are identified. By describing a complex clinical case, and having taken into consideration both aims and materials, the techniques of prosthetic rehabilitation are illustrated using obturator devices. The results of the various phases are examined.
