This study presents an easy, time-saving method to fix open-type hollow obturators. Visible light-activated materials are used to reline and seal obturators, improving patient comfort and hygiene.

Area of Science:

  • Dental prosthetics
  • Materials science in dentistry

Background:

  • Open-type hollow obturators present challenges including difficult cleaning, food trapping, and inadequate support.
  • Existing methods for managing these issues can be time-consuming and complex.

Purpose of the Study:

  • To describe a simple and efficient procedure for modifying open-type hollow obturators.
  • To utilize visible light-activated denture base materials for obturator relining and defect closure.

Main Methods:

  • A novel technique employing visible light-activated denture base materials as a reline agent.
  • Application of the material to close the open type interim obturator, addressing internal surface and support issues.

Main Results:

  • The described procedure offers a time-saving solution for obturator modification.
