Abstract EN
Background : lining materials have been widely used for prosthodontics rehabilitation.
One unresolved problem is the easy adherence of Candida to these materials because roughness of porous surface, inadequate adhesion of silicon to acrylic denture base is the most problem of the silicone soft liner material.
Although silicone soft liner materials have more stability when compared with acrylic based type of soft liner material but they still show several disadvantages like the material have susceptibility to water absorbed of solvents and particular water and loss of soluble components and this lead to effect the strength of bond and change visicoelasticity of material.
The purpose of this study was to compare among four silicone based soft liner materials (perm flex and Molloplast, Ufi Gel SC and permafix) in invitro investigations properties shear bond, water sorption and solubility and surface roughness test.
Materials and methods : Seventy two specimens of 4 silicon based soft lining material, 24 for each material, 6 for each test, the specimens of shear bond strength test were subjected to tension in Instron machine with speed rate was 0.5 mm / minute to measure shear bond strength by N / mm .
The surface roughness samples were measured by using profilometer device.
The final test of this study was water sorption and solubility according to ADA specification No.
12 (1999) All data were collected and analyzed by ANOVA and LSD tests, the finding showed the permaflex had high shear bond strength followed by Molloplast, Permafix respectively and the least bond strength was for Ufi Gel Results : of surface roughness test showed the same mean value among most of the materials.
For water sorption and solubility test the permaflex had the lowest value and followed by Molloplast and was not significant change between permafix and Ufi Gel SC.
Conclusions : indicated that permaflex shows better properties when compared with other soft liner materials and that hot cure polymerizing soft liner material showed proper properties when compared with auto polymerizing soft liner material.
