Area of Science:

  • Oncology
  • Dental Materials Science
  • Radiotherapy

Background:

  • Oral cancer radiotherapy requires precise radiation delivery to tumors while protecting surrounding healthy tissues.
  • Conventional tongue-shielding radiation stents, made from polymethyl methacrylate with lead-bismuth-tin alloy, involve complex and time-consuming fabrication processes.
  • These conventional methods necessitate multiple clinical and laboratory appointments, impacting treatment efficiency and patient comfort.

Purpose of the Study:

  • To describe a simplified direct fabrication method for tongue-shielding radiation stents.
  • To introduce a novel polyvinyl siloxane-metal composite as an alternative shielding material.
  • To highlight the advantages of this new system in terms of ease of use and reduced treatment time.

Main Methods:

  • Fabrication of a tongue-shielding stent using a two-component polyvinyl siloxane-metal composite putty.
  • Integration of the composite material with impression putty for direct stent fabrication.
  • Clinical evaluation of the new fabrication method and material properties.

Main Results:

  • The polyvinyl siloxane-metal composite offers comparable radiation shielding to conventional alloys.
  • The direct fabrication method significantly reduces the number of clinical appointments required.
  • The material is easy to handle and allows for efficient collaboration between dental and medical professionals.

Conclusions:

  • A simplified direct fabrication method using a polyvinyl siloxane-metal composite offers an efficient alternative for creating tongue-shielding radiation stents.
  • This novel approach streamlines the fabrication process, reduces patient treatment time, and improves interdisciplinary collaboration in oral cancer radiotherapy.
  • The material provides effective radiation shielding, enhancing patient safety and treatment outcomes.
