Abstract EN
Background : In dentistry, dentist takes the advantages of soft lining materials due to the viscoelastic properties.
The major problem is the adhesion of the soft liner with the denture base material.
Materials and Methods: Heat cured of high impact acrylic resin specimens prepared with dimensions 75 x 13 x 13mm for shear bond strength test, soft lining material (Refit and Mollosil) with a 3-mm thickness and used to join each two acrylic blocks.
Also four specimens with the same previous dimensions utilized for chemical and physical surface analysis.
The specimens grouped as control (without plasma) and experiment (with oxygen plasma) treated high impact acrylic specimens.
Results : Plasma treatment increased the shear bond strength for both Refit and Mollosil soft lining material after immersion in distilled water for 30 days as compared with the control group, also there was decrease in shear bond strength for both Refit and Mollosil soft lining material of the experimental group after immersion in denture cleanser for 30 days as compared with the control (without plasma treated) group.
AFM analysis revealed that oxygen plasma treatment led to formation of (pits and protuberances) that increase the surface area and increase the shear bond between soft liners and high impact acrylic denture base.
Conclusions : Oxygen plasma surface treatment was an effective method for increasing adhesion by physical topographic surface (due to the plasma etching process which in turn led to removal of some material from the surface and this led to increase the bond strength
