Successful construction of the denture using two different types of materials relies partly on a satisfactory bond between the materials. The most common reason for failure of a soft-lined denture was the failure of "adhesion" between the liner and denture base. To improve the bond between a soft liner and a denture base material, various surface pretreatments for the denture base acrylic have been studied and used. They may be categorized into mechanical, chemical, mechano-chemical and plasma treatment. A detailed review of these existing surfaces pretreatment is lacking in the literature.
