A novel photoactivated spacer method improves silicone soft lining polymerization onto acrylic denture bases. This technique ensures optimal fit and thickness, enhancing denture durability and preventing microbial invasion or margin peeling.

Area of Science:

  • Dental Materials Science
  • Polymer Chemistry
  • Biomaterials Engineering

Background:

  • Denture soft lining materials are crucial for patient comfort and function.
  • Conventional polymerization methods can lead to challenges in achieving precise fit and long-term durability.
  • Microbial contamination and material delamination at the denture margins are common issues.

Purpose of the Study:

  • To introduce a new method for polymerizing silicone soft lining materials with acrylic resin bases.
  • To enhance the precision and ease of application for soft lining materials.
  • To improve the long-term durability and clinical performance of dentures.

Main Methods:

  • Utilizing a photoactivated spacer during the polymerization process.
  • Precisely positioning the spacer to cover attached mucosa without extending to denture borders.
