Comparision of the tensile and peel bond strength of the silicone and acrylic soft liner following denture base treatment: An In vitro study
Journal Title: International Journal of Medical and Health Research - Year 2019, Vol 5, Issue 3
Abstract
Aim: The study was conducted to compare the peel and tensile bond strength of some of the commercially available soft liners with denture base resin and the effect of surface pre-treatment of denture base resin with methyl methacrylate. To compare the tensile and peel bond strength of the auto polymerized acrylic and silicone based soft liners bonded to the heat cure denture base. Materials and Methods: 80 Acrylic blocks were then divided into 4 groups. Preparation of Blocks and Test samples were done. Tensile bond strength and Peel bond strength were measured. Results: Use of methyl methacrylate pretreatment for 180 seconds was found to be the most effective method to increase bonding ability of the silicone soft liner to acrylic denture base. Conclusion: The tensile and peel bond strength of acrylic soft liner bonded to pretreated surface of the acrylic denture base doesn’t shows any significant improvement with acrylic soft liner bonded to the untreated surface of the acrylic denture base.
