An automated tissue retention system generally comprises an oral appliance retractably coupled to a covering which is secured to an anterior portion of the tongue. Once placed within a subject's mouth, the appliance may be maintained in a closed configuration while the subject's mouth remains closed. However, as the subject sleeps and the tongue becomes hypotonic, the subject's mouth typically opens during a sleep disordered event. The appliance may be actuated by the separation between the mandible and maxilla to have greater tension and thus retract or pull anteriorly the covering adhered to the tongue. As the covering pulls the tongue anteriorly or maintains a position of the tongue, the base of the tongue may be inhibited or prevented from collapsing posteriorly against the phryngeal tissue walls and thereby allow the subject to breathe normally.
