Comparative Effect of Incorporation of ZrO2, TiO2, and SiO2 Nanoparticles on the Strength and Surface Properties of PMMA Denture Base Material: An In Vitro Study

Abstract: Objective. This study aimed to investigate the effects of nanoparticles (zirconium dioxide (ZrO2), titanium dioxide (TiO2), and silicon dioxide (SiO2)) on the flexural strength, impact strength, hardness, and wear resistance of the acrylic resin denture base material. Materials and Methods. Acrylic resin specimens were fabricated in dimensions according to American Dental Association (ADA) specifications per test. Specimens were divided according to nanofiller into four groups; unmodified as control, ZrO2 (Z),… Show more

“…Finally, 15 articles that fulfilled the inclusion criteria were included and is depicted as modified PRISMA-2020 flow diagram made most optimal for the current review. [44][45][46][47][48][49][50][51][52][53][54][55][56][57][58]59 (Figure 1). Out of 15 studies included 14 were in-vitro studies and one was a randomized control trial, 7 studies evaluated antimicrobial properties of TiO 2 NP, 45,47,51,53,54,57,58 5 studies evaluated SR, 46,50,51,52,58 8 studies evaluated SH [44][45][46][48][49][50]54,56 and 2 studies evaluated both.…”

“…The current study results demonstrated that there was a statistically significant increase of the surface roughness of acrylic resin material by adding 1.0% silanized SiO2 Nps compared to the control group. This finding might be accredited to the different particle size of nano fillers compared to that of acrylic resin, which may have led to the creation of filler aggregates on the surface that might separate during finishing and polishing, creating spaces and trenches in the surface (32) . This finding agrees with a study which evaluated the surface roughness of reinforced acrylic resin using scanning electron microscope.…”

“…ZrO 2 -NP are also used in drug delivery systems for itraconazole and bisphosphonates (Keleştemur and Yeşilay, 2020; Talegaonkar et al, 2022). Additionally, they have been used in optical coating, and also as a catalyzing agent in organic reactions (Azmy et al, 2022; Migdadi et al, 2022; Salem et al, 2022; Ullah et al, 2020).…”
