Abstract

Objective: Zirconium dioxide (ZrO2) nanofillers were added to denture liners to improve their physical properties. The main goal of this research was to evaluate the impact of adding nano zirconium oxide (ZrO2) fillers on color change, water sorption and solubility of silicone and acrylic denture liners.

Materials and Method: The surface of ZrO2 nanoparticles was modified via treatment with the silane coupling agent (3-aminopropyl) triethoxysilane. Fourier transform infrared spectroscopy analysis was performed to characterize surfaces untreated or treated with ZrO2. After modification, these nanoparticles were incorporated into silicone and acrylic denture liners. Three subgroups were assigned for each test method. Kruskal-Wallis and Mann-Whitney U tests were used for the statistical analysis (p ≤ 0.05).

Results: Water sorption and solubility in water values decreased with the addition of modified ZrO2 nanofiller in both test groups (respectively, acrylic-based tissue conditioner: p = 0.040 and p = 0.020; silicone-based denture liner: p < 0.001 and p = 0.017). The acrylic-based tissue conditioner test group with 1% modified ZrO2 nanofiller showed the greatest color change (ΔΕ = 37.94 ±6.62), whereas the silicone-based denture liner group with 0.5% modified ZrO2 nanofiller presented the lowest (ΔΕ = 5.02 ±2.30).

Conclusion: Modified ZrO2 nanofiller–incorporated silicone-based denture liners might show better clinical success than acrylic ones according to the evaluated parameters.

Nano zirkonyum dioksit doldurucu ilavesinin protez astarlarının renk değişimi, su emilimi ve çözünürlüğüne etkisi

Abstract

Amaç: Zirkonyum dioksit (ZrO2) nanodoldurucuları, protez astarlarına fiziksel özelliklerini iyileştirmek amacıyla ilave edilmiştir. Bu çalışmanın amacı, ZrO2 nanodoldurucu ilavesinin silikon ve akrilik protez astarlarının renk değişimi, su emilimi ve suda çözünürlüğü üzerindeki etkisini değerlendirmektir.

Gereç ve Yöntem: ZrO2 nanopartiküllerinin yüzeyi, silan bağlama ajanı (3-aminopropil) trietoksisilan ile işlemden geçirilerek modifiye edildi. Muamele edilmemiş ve ZrO2 ile muamele edilmiş yüzeyleri karakterize etmek için Fourier dönüşümü kızılötesi spektroskopi analizi gerçekleştirildi. Modifikasyondan sonra, nanopartiküller silikon ve akrilik esaslı protez astarlarına ilave edildi. Her test yöntemi için üç alt grup oluşturuldu. İstatistiksel analizde, Kruskal-Wallis ve Mann-Whitney U testleri kullanıldı (p ≤ 0.05).

Bulgular: Her iki test grubunda da ZrO2 nanodoldurucu ilave edilmesiyle su emilimi ve sudaki çözünürlük değerleri azaldı (sırasıyla akrilik esaslı doku düzenleyici: p = 0.040 ve p = 0.020; silikon esaslı protez astarı: p <0.001 ve p = 0.017). %1 modifiye edilmiş ZrO2 nanodoldurucu ilave edilmiş akrilik esaslı doku düzenleyici test grubu en fazla renk değişimini gösterirken (ΔΕ = 37.94 ± 6.62), %0.5 modifiye edilmiş ZrO2 nanodoldurucu içeren silikon esaslı protez astarı en az renk değişimi gösterdi (ΔΕ = 5.02 ± 2.30).

Sonuç: Modifiye edilmiş ZrO2 nanodoldurucuların protez astarlarına ilavesi, bu malzemelerin fiziksel özelliklerini olumlu yönde etkilemiştir.
