Hybrid prostheses in total maxillectomy

Abstract

Maxillectomies triggered by cancer lesions leave as sequels the communication between oral and nasal cavities. This allows for the exchange of oral and nasal fluids which hinders speech, mastication and deglutition (swallowing) It also causes facial deformities which lower the patient´s self esteem .To restore these functions, we need unconventional, modified, and hard to build prosthetic devices such as the design of a hybrid retention prosthetic obturator (swing lock).
