When bilateral total maxillectomy was undertaken, prognosis was negative. The patient was fully edentulous in the lower section, therefore, a light, retentive and functional shutter had to be devised, to primarily achieve a barrier between oral and nasal cavities. The shutter provided support and stability, and this, along with a full lower denture , preempted the need to use adhesive material.
Al realizarle una maxilectomía total bilateral, su pronóstico era desfavorable además de ser desdentado total inferior, por lo que hubo la necesidad de elaborar un obturador funcional, retentivo y ligero, que lograra primeramente una barrera entre la cavidad bucal y nasal; además logró dar soporte y estabilidad aunada a la elaboración de la dentadura total inferior, sin la necesidad de utilizar adhesivos.
