Effectiveness of silicone-based resilient denture liners on masticatory function: A randomised controlled trial

Area of Science:

• Dental prosthetics
• Biomaterials science
• Clinical dentistry

Background:

• Edentulous patients often experience reduced masticatory function.
• Resilient denture liners are explored to improve denture comfort and function.
• Previous studies suggested benefits for masticatory function with resilient liners.

Purpose of the Study:

• To compare masticatory function between silicone-based resilient denture liners and conventional dentures.
• To evaluate the impact of resilient liners on masticatory performance and occlusal force.

Main Methods:

• Randomized controlled trial involving edentulous patients receiving new complete dentures.
• Comparison between conventional denture bases (CD group) and silicone-based resilient denture liners (RD group).
• Assessment of masticatory performance (gummy jelly) and maximum occlusal force at baseline and follow-up points.

Main Results:

• Masticatory performance was lower in the RD group compared to the CD group.
• Maximum occlusal force was significantly higher in the RD group than in the CD group.
• Occlusal force increased over time in the RD group, while masticatory performance improved in the CD group.

Conclusions:

• Silicone-based resilient denture liners enhance maximum occlusal force in edentulous patients.
• These liners do not improve masticatory performance, particularly for textured foods like gummy jelly.
• Challenges may persist in food texture mastication despite the use of resilient liners.
