[Elastomers and peripheral seal in complete maxillary dentures]

Area of Science:

• Dental prosthetics
• Biomaterials science

Context:

• Denture retention relies on physical factors like adhesion and atmospheric pressure.
• Accurate recording of the periphery is crucial for optimal denture flange design.

Purpose:

• To compare the efficacy of different materials (Kerr compound, Neo-Plex, Impregum) for recording the periphery of maxillary full dentures.
• To determine which material best achieves optimal denture flange height and width without over-extension.

Summary:

• The study evaluated adhesion and atmospheric pressure in denture retention, focusing on salivary meniscus formation and periphery seal.
• Comparative analysis of Kerr compound, Neo-Plex, and Impregum for border recording revealed Impregum yielded the highest and thickest borders.
• Impregum is identified as the material of choice for optimal functional periphery seal recording in maxillary full dentures.

Impact:

• Establishes Impregum as the preferred material for maximizing denture retention through precise border recording.
• Provides evidence-based guidance for dental professionals selecting materials for full denture fabrication.
• Contributes to improved patient outcomes by enhancing denture stability and comfort.
