“…The pain is relieved by reducing the impact force during mastication and dispersing the force widely over the alveolar ridge to give a cushioning effect. Therefore, the clinical performance of soft lining materials is considered to relate with the viscoelastic properties 2) . The application of a soft lining material to the mandibular denture can also increase the patient's masticatory performance and biting force, thereby improving the chewing rhythm 3) .…”

The purpose of the present study was to compare the properties required for the clinical application of soft lining materials containing a fluorinated monomer versus that of conventional materials in an effort to develop a new soft lining material with long-term stable viscoelastic properties. Four soft lining materials were examined. Two experimental materials containing dodecafluoroheptyl methacrylate (SR12F) or tridecafluorooctyl methacrylate (SR13F) were prepared. Two commercial soft lining materials, one acrylicbased and one silicone rubber-based, were selected as reference materials. Shore A hardness, viscoelastic properties, water sorption, solubility, and staining resistance were evaluated. The Shore A hardness and the displacements were analyzed with two-way analysis of variance (ANOVA) and Tukey's HSD test. The water sorption, the solubility and the color change were analyzed with one-way ANOVA and Tukey's HSD test. The significance level was set at 0.05. SR12F and SR13F showed greater viscous flow, low water sorption, low solubility, and good staining resistance compared to the commercial products. The results indicate that the soft lining materials containing fluorinated monomers might have a potentially long-term stable viscoelastic behavior.

“…There are two types of commercial soft liners: those based on acrylic resin and those based on silicone elastomers [10]. In the oral cavity environment, silicone liners are more resistant to distortion, hardening and debonding from the denture base than acrylic liners [11][12][13].…”

Background. Silicone-based liners are widespread materials in prosthetic dentistry. Their mechanical properties have to meet several key requirements such as adequate adhesion to denture base polymers in order to provide right function of masticatory system and oral hygiene. Objectives. The aim of this paper was to evaluate and compare tensile and shear bond strengths values of three modern autopolimeryzed silicone relining materials bonded to acrylic plates. Material and Methods. Three silicone-based soft relining materials were investigated in this study (A-Soft Line 30, Bosworth Dentusil and Elite Super Soft). A total of 78 specimens were prepared: 13 of each material (total: 39) for testing tensile bond strength and 13 of each material for testing shear bond strength (total: 39). The obtained data were analyzed statistically.
