Flexural properties of additive manufactured resin designated for interim fixed dental prosthesis: Effect of nanoparticles, build direction, and artificial aging.

Objective: This study investigates the flexural strength and elastic modulus of three-dimension (3D) printed interim resin (ASIGA) incorporating zirconium dioxide (nano-ZrO) and silicon dioxide (nano-SiO) nanoparticles (NPs) with different build direction and after artificial aging.

Methods: Three hundred 3D-printed specimens were used for testing. Groups were modified with nano-ZrO or nano-SiO at concentrations of 0.

Nanoparticle-Modified 3D-Printed Denture Base Resins: Influence of Denture Cleansers on the Color Stability and Surface Roughness In Vitro.

This study aimed to evaluate the influence of denture cleansers on the color, stability, and surface roughness of three-dimensional (3D)-printed denture base resins modified with zirconium dioxide nanoparticles (nano-ZrO). A total of 440 specimens were fabricated using one heat-polymerized resin, and two 3D-printed resins (NextDent and ASIGA). According to the nano-ZrO content, the specimens for each resin were divided into five groups (0%, 0.

Impact of Nanoparticle Addition on the Surface and Color Properties of Three-Dimensional (3D) Printed Polymer-Based Provisional Restorations.

This study aimed to evaluate and compare the impact of additives such as ZrO and SiO nanoparticles (ZrONP or SiONP) on the hardness, surface roughness, and color stability of 3D printed provisional restorations. Two hundred samples in total were printed using 3D printed resins (ASIGA, and NextDent). Each resin was modified with ZrONPs or SiONPs in two different concentrations (0.

Flexural strength of 3D-printed nanocomposite provisional resins: Impact of SiO and ZrO nanoparticles and printing orientations in vitro.

Purpose: The aim of this study was to investigate and compare the influence of zirconium dioxide nanoparticles (ZrO NPs) and silicon dioxide nanoparticles (SiO NPs) addition and printing orientation on the flexural strength (FS) of provisional three-dimensional (3D) printing resins undergoing thermal cycling (TC).

Methods: Three dimensional-printed resin (NextDent C&B MFH) was used to fabricate 300 bar-shaped specimens (25 × 2 × 2 mm ). The ZrO NPs and SiO NPs specimens were divided into two groups, then subdivided into three groups, based on the nanoparticle concentration (i.
