Summary
Coating temporary soft denture liners with specific surface sealants like Palaseal or mono-poly can significantly enhance their resiliency. This study found that these coatings improved the durability of soft denture liners under laboratory conditions.
Area of Science:
- Dental Materials Science
- Biomaterials Engineering
Background:
- Temporary soft denture liners are crucial for patient comfort and function.
- Previous research indicated that methyl methacrylate resin coatings extend liner resiliency.
Purpose of the Study:
- To evaluate the effect of two denture surface sealants on the resiliency of three temporary soft denture liners.
- To assess the impact of thermocycling on the performance of coated and uncoated liners.
Main Methods:
- Three soft denture liners (Lynal, Coe Soft, Visco-Gel) were tested.
- Samples were coated with Palaseal or mono-poly, or left uncoated.
- Specimens underwent 500 cycles of thermocycling (5°C to 45°C).
- Resiliency was measured by energy absorbed during compression testing.
Main Results:
- Significant differences in resiliency were observed among materials and treatments (p < 0.0001).
- Specific combinations, such as Palaseal or mono-poly on Lynal and Palaseal on Visco-Gel, showed significant improvements.
- Statistical analysis confirmed the impact of both liner material and sealant treatment on resiliency.
Conclusions:
- Surface coating with Palaseal or mono-poly significantly increased the laboratory resiliency of Lynal and Visco-Gel soft denture liners.
- The findings suggest that surface sealants can be a viable method to improve the longevity of temporary soft denture liners.
