Summary
Long-term soft denture lining (LTSDL) materials improve denture comfort but face challenges. Enhancing their resistance to Candida albicans and improving debonding strength are crucial for better clinical performance.
Area of Science:
- Biomaterials Science
- Dental Materials Science
- Clinical Dentistry
Background:
- Long-term soft denture lining (LTSDL) materials mitigate denture-related trauma.
- Oral environment factors negatively impact LTSDL mechanical and performance characteristics.
- Candida albicans colonization remains a significant clinical challenge for LTSDLs.
Purpose of the Study:
- To review the limitations of current LTSDLs, focusing on mechanical properties and oral environment interactions.
- To highlight the challenges associated with silicone-based LTSDLs (SLTSDLs) and acrylic-based LTSDLs (ALTSDLs).
- To identify areas for future research to improve LTSDL performance and longevity.
Main Methods:
- Review of existing literature on LTSDL materials, their properties, and clinical performance.
- Comparative analysis of silicone-based LTSDLs (SLTSDLs) and acrylic-based LTSDLs (ALTSDLs).
- Discussion of limitations in current bond strength testing methods for LTSDLs.
Main Results:
- SLTSDLs offer more stable hardness, sorption, and solubility than ALTSDLs but exhibit greater debonding susceptibility.
- Existing bond strength tests may not accurately represent clinical stability.
- All LTSDLs show discoloration tendencies and are affected by cleansers, impacting mechanical properties.
Conclusions:
- Further research is essential to enhance the microbiological resistance of LTSDLs, particularly against Candida albicans.
- Improving debonding strength and developing more accurate clinical stability assessments for SLTSDLs are critical.
- Optimizing LTSDL formulations to resist oral environmental degradation and discoloration is needed for improved patient outcomes.
