Various Mechanical Properties of Denture Liners Combined with Zirconium Oxide Nanoparticles

Debonding from the denture base, poor resistance to tearing, and increase in hardness are some of problems with liners. This research purposed analyze changes mechanical characteristics tissue conditioner liner concerning interaction material zirconium oxide nanoparticles (ZrO2-NPs). The surface functionalization ZrO2-NPs was done using a silane coupling agent as modifier for better integration them into Then, they were added acrylic- silicone-based two different percentages (0.5% 1% by weight; respectively). performed tests tear strength, tensile bond (Shore A). 0.5% test groups displayed statistically significantly lower strength values than conditioners without (p < 0.001). However, results all subgroups soft similar = 0.239). In lining material, highest obtained (tissue conditioner; 0.58±0.11 N liner; 4.10±0.58 N). shore A both tested determined no meaningful differences 0.100). All liners had satisfactory clinically adequate bonding base prosthetic.
