Obstructive sleep apnea (OSA) is characterized by repetitive episodes of partial or complete upper airway closure leading to
diminished (hypopenia) or absent airflow (apnea) into the lungs despite persistent inspiratory effort. The treatment of the OSA varies
from conservative therapy to invasive surgical measures. Placement of intraoral prosthesis is a conservative, non invasive means of
treatment modality with the goal of positioning the tongue and mandible at an increased vertical and protrusive position to minimize
the possibility of oropharyngeal obstruction. This article describes clinical and laboratory technique for the fabrication of mandibular
advancement prosthesis for the management of obstructive sleep apnea.
