Influence of Different Denture Base Resins on the Degree of De-Bonding in Terms of the Width of the Micro-Gap Created at Resin Base - Soft Liner Interface: An In-Vitro Study
Dr. Ankit Verma [3] | Dr. Akanksha Kumari
Abstract: A major drawback of soft liner materials is their limited durability. The study was carried out with an intent to investigate the durability of silicone soft liner with three commonly used acrylic based denture resin material heat cure, high impact and self cure and relate them to the width of the micro-gap formed at resin base-soft liner interface after accelerated aging procedure. Greater the width of micro-gap formed, greater will be the potential for micro-leakage and microbial colonization, faster will be its de-bonding from the denture base and hence lower will be its durability. The rationale behind this study was to rate the three commonly used forms of acrylic based denture resin materials (heat cure, high impact, self cure) on the basis of their ability to form durable bonds with the silicon soft liner and offer suggestions to the dental clinicians regarding which acrylic based denture resin material should be preferably chosen for complete denture fabrication in cases where a silicone soft liner material is indicated to ensure optimum durability of the prosthesis.
