Positional stents are used to move or displace tissues out of the field of radiation. This clinical report outlines a technique used in the fabrication of a radiographically detectable intraoral positional radiation stent using a visible light-cured resin (Triad, Dentsply International Inc., York, Pa.). A 64-year-old white man was referred from radiation therapy for a radiation stent that would position the mandible and tongue out of the primary field of radiation. The patient had a 2 x 4 cm lesion of the soft palate extending from the uvula into the anterior right tonsillar pillar with central ulceration. A biopsy demonstrated invasive squamous
