Impact of two different nanoparticle types on acrylic resin denture base porosity, water sorption, and solubility
https://doi.org/10.36377/ET-0202
Abstract
INTRODUCTION. Acrylic resins are widely and primarily utilized in prosthodontics as the basis material for dentures. The acrylic resin denture base’s porosity is an inappropriate feature. During prosthesis use, water absorbed by the acrylic resin’s surface acts as a plasticizer and may cause volume fluctuations
AIM. To assess how adding two different kinds of nanoparticles – silicon dioxide and titanium dioxide – affects the acrylic resin denture base’s porosity, water sorption, and solubility.
MATERIALS AND METHODS. Thirty heat-cured acrylic samples were used for the porosity and solubility tests, and each test’s samples were split into three set: control group – heat cured acrylic resin alone, heat cured acrylic resin material with 2% of TiO2 nanoparticles and heat cured acrylic resin with 2% of SiO2 nanoparticles group. A rectangular sample measuring 50 × 4 × 2 mm ± 1 mm was created for the porosity test, while a disc sample measuring 40 × 2.5 mm was created for the water sorption and solubility test.
RESULTS. The TiO2 group had the highest mean porosity test value (2.504), whereas the Control group had the lowest (1.468). The SiO2 group had the greatest mean value for the water sorption test (1.28572430), whereas the TiO2 group had the lowest (0.66882004). The control group had the highest mean solubility test score (0.649619315), while the SiO2 group had the lowest (0.45170539).
CONCLUSIONS. The porosity of heat-cured acrylic resin was not decreased by adding TiO2 or SiO2. Water sorption is reduced when TiO2 is added. Solubility was also reduced by adding 2% SiO2.
