Summary
This study measured the dynamic contact angle and surface free energy of resilient denture lining materials. Findings indicate these materials enhance denture stability, with some showing better wettability than others.
Area of Science:
- Materials Science
- Biomaterials Engineering
- Dental Materials Science
Background:
- Wettability of long-term resilient denture base lining materials is crucial for performance.
- Previous wettability data relied on static methods, limiting dynamic insights.
- Understanding surface properties is key to improving denture stability and patient comfort.
Purpose of the Study:
- To determine the dynamic contact angle and surface free energy of various long-term resilient denture lining materials.
- To compare the wettability of different soft-lining materials using a rapid method.
- To assess the implications of wettability for denture stability under dislodgment forces.
Main Methods:
- Dynamic contact angle measurements were performed on a range of resilient denture lining materials.
- Surface free energy properties were determined for each material.
- Equilibrium contact angle and contact angle hysteresis were analyzed.
Main Results:
- Flexor and Novus materials exhibited the least wettability based on equilibrium contact angle.
- Molloplast-B and CoeSuper-Soft showed wettability similar to Trevalon.
- Contact angle hysteresis suggested all tested soft-lining materials could enhance denture stability.
Conclusions:
- Dynamic contact angle measurement is an efficient method for assessing denture lining material wettability.
- The tested soft-lining materials demonstrate potential to improve denture stability.
- Surface free energy varied, with soft-lining materials generally lower than Trevalon.
