Bond strength of long-term chair-side denture soft lining materials

Objectives: The aim of the study was to evaluate the bond strength properties of four chair-side silicone denture soft lining materials (1. GC Reline Soft, 2. Ufigel SC, 3. Elite Soft Relining and 4. Tokuyama Sofreliner S) and to compare their properties with those of a heat-cured silicone lining material Molloplast B.

Methods: Tensile and shear bond strengths were measured using a Lloyd Instruments Materials Testing Machine (LR 5K), at a crosshead speed of 20 mm/min for both tensile and shear testing.

Data were tested for statistical differences, using Kruskal-Wallis test followed by Box-and-Whisker plots.

Results: Lining material 1 exhibited the highest shear bond strength (1.25 MPa), though this was not significantly higher than the heat-cured lining material . The other materials were significantly weaker, with material 2 being the weakest (0.49 MPa). Material 1 also exhibited the highest tensile bond strength, though this was again not significantly higher than the heat-cured lining material. Material 4 (0.74 MPa) was significantly weaker than any of the other materials.

Conclusions: Significant differences existed between the bond strength properties of the silicone auto-polymerising denture soft lining material materials.
