Intraoral stent for head and neck radiotherapy using 3D technology: an integrative review

The aim of the study was to conduct an integrative review on intraoral stents for head and neck radiotherapy using 3D technology. For data collection, the words were used: "intraoral stent", "oral cancer" and "3D", with their combination performed using the Boolean operator AND. Only articles in English were selected from the PubMed and LILACS databases. The search process was conducted between August and October 2024. Eight articles were found, of which seven met the established inclusion criteria. The articles demonstrate that the use of 3D technology optimizes the fabrication time of intraoral stents, directs isodose distribution to the treated area while preserving adjacent healthy tissues, and reduces side effects during the irradiation period. Evident advances in the literature regarding the innovation in the production of intraoral stents, such as 3D printing, have demonstrated effectiveness and benefits in this treatment modality.
