Wettability Assessment of Room-Temperature Soft Liners Incorporated with Strontium Titanate Nanoparticles

Background: Soft denture liners are widely used in prosthodontics for their ability to cushion masticatory forces and enhance comfort in patients with compromised oral mucosa. However, conventional liners often exhibit limitations such as poor adhesion to the denture base, microbial colonization, and inadequate mechanical stability. Materials and Methods: Strontium titanate (SrTiO3) nanoparticles were incorporated into a self-cured soft denture liner. Three equal groups of fifteen specimens were created, each of which contained 0%, 1%, and 1.5% SrTiO3 by weight. All procedures were conducted under simulated intraoral temperature, following manufacturer guidelines. Results: The analysis revealed statistically significant differences across all tested parameters, indicating that the incorporation of SrTiO3 had a substantial effect on the Physical properties of liner material. Conclusion: The addition of SrTiO3 nanoparticles resulted in a measurable decrease in the wettability of the soft liner. These findings suggest that SrTiO3 holds promise for enhancing the performance, durability, and biocompatibility of soft denture lining materials.
