Abstract
To improve the adhesion between the silicone resilient liner and acrylic denture bate, two experimental adhesives were prepared, one was a γ-MPTS/EA copolymer dissolved in toluene for the condensation RTV silicone rubber, and the other was the condensation product between HEMA/MMA copolymer and DMVCS dissolved in toluene for the addition RTV silicone rubber. Acrylic rods and condensation or addition RTV silicone rubber were bonded with these adhesives.Their bonding durabiity was evaluated by the measurement of tensile bond strength after the bonded specimens were kept in 80℃ water for a certain time. The acrylic rods bonded to the addition RTV silicone rubber with the experimental adhesive showed excellent durability against hot water; that is, the tensile bond strength of the bonded specimens did not change, after the specimens were kept in 80℃ water for ten days. Therefore, the silicone denture liner with high bonding durability can be developed by the application of this experimental adhesive.
