Abstract: The intraoral radiotherapy stent includes a hollow tube having opposed first and second open ends. First and second discs are provided, each having opposed inner and outer faces. A first shaft is secured centrally to the inner face of the first disc and extends axially therefrom. The first shaft is adjustably received within the hollow tube through the first open end thereof. A second shaft is secured centrally to the inner face of the second disc and extends axially therefrom. The second shaft is adjustably received within the hollow tube through the second open end thereof. First and second lip retractors are mounted on the hollow tube for holding the patient's mount open during a radiotherapy procedure or the like, and a tongue depressor is also mounted on the hollow tube to depress the patient's tongue and minimize tongue movement during radiotherapy or the like.
