Abstract

Since periods, polymethyl methacrylate (PMMA) has been used to fabricate the dentures. The acrylic denture base prostheses have their own advantages and disadvantages. Innovation of Flexible dentures are an excellent volition to conventionally used methyl methacrylate dentures, which not only give excellent aesthetics and comfort but also acclimatize to the constant movement and inflexibility in incompletely edentulous cases. This study has been accepted to estimate and compare the Flexural strength, face roughness and water sorption of two flexible denture base resins i.e. Valplast, Macroflexi and a heat cure denture base resin Acralyn-H. Hence, the objective of this study was to compare & estimate the Flexural Strength, Surface Roughness and Water sorption of two different Flexible denture base accoutrements and Heat cure denture base material. Twenty test samples of each material were divided into Group- A, Group- B, Group- C independently which were used for Flexural strength test and face roughness testing. Water sorption values were calculated using the formula and attained.
