SandblastAbstract
Background: One of the most serious problems with silicone soft liners is that they cannot cling to the acrylic denture foundation. The peel test is an appropriate method for assessing the binding strength of soft liners to denture base resin because the forces that the lining material is clinically exposed to are closely linked to the peel and tear test.
Objective of study: Analyzing the impact of sandblasting on the soft liners' ability to adhere to denture base resins' peel bonds.
Materials and Methods: Forty samples 64 x 10x 3 mm (length, width, and thickness), respectively of heat-cured acrylic soft denture liner materials. According to the types of material used, 20 specimens for CAD/ CAM and other 20 for traditional acrylic denture base material were constructed. The specimens were subdivided into two main groups (control group and sandblasting group). CAD/CAM specimens were created by cutting Pre-polymerized PMMA blocks with an In Lab MC X5-miller for PMMA plastic burs.
Results: The results showed that the sandblast treatment produced a higher mean value of Peel strength for conventional acrylic specimens in comparison to control. An Independent t-test reveals no significant difference (P>0.05) between groups. For the CAD/CAM approach, the sandblast group produced the lowest mean value of peel bond strength. Additionally, significant differences (P<0.05) for the CAD /CAM were found between control groups.
Conclusion: Particularly in terms of their mechanical properties, CAD/CAM polymers outperform conventional resins. It should be noted that variations in the features may be caused by differences in the resins' composition as well as the production processes. Also, the results of this study show that sandblasting increased the Peel bond strength of resilient lining materials to denture base resins and that the Peel bond strength was considerably higher in the surface-treated groups than in the control groups.
