Effect of Carbon Stabilizing Elements on WC Cemented Carbides with Chromium Steel Binder

Medžiagotyra, 2019
High price, limited availability and toxicity of cobalt motivates researchers and material engineers to find alternative binder systems for WC cemented carbides. Iron and iron alloys are promising candidates for complete cobalt substitution.

Effect of surface treatments on the bond strength between additively manufactured or injection‐molded high‐performance polymers and titanium

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the effect of surface treatment and fabrication techniques of high‐performance polymers on their shear bond strength (SBS) to grade IV titanium. Materials and Methods A total of 120 pre‐milled titanium abutments were sectioned.

Optical stability of 3D‐printed and milled zirconia after artificial aging and immersion in liquids: An in vitro study

Journal of Prosthodontics, EarlyView.
ABSTRACT Purpose To assess the impact of artificial aging and immersion in common liquids on the optical properties of 3D‐printed and milled zirconia. Materials and Methods Monolithic zirconia discs (N = 100) were fabricated using two methods: 3Y‐TZP for milling (e.max ZirCAD LT BL, Ivoclar Vivadent) and printable 3Y‐TZP material (LithaCon 3Y 230) for ...

Effect of margin thickness and cement gap on the fabrication and fit accuracy of additively manufactured crowns in definitive resins with different filler content

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate how commercially available composite resins in varying filler content affect the fabrication and fit accuracy (trueness and precision) of additively manufactured (AM) definitive crowns with different margin thickness and cement gaps by comparing them to subtractively manufactured (SM) polymer‐infiltrated ceramic crowns ...

Effect of material, prosthesis height, and aging on the fracture strength of additively and subtractively manufactured implant‐supported cantilevered prostheses

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to evaluate the inherent and after cyclic loading fracture strength of implant‐supported cantilevered fixed prostheses fabricated from recently introduced additively manufactured (AM) and subtractively manufactured (SM) materials, considering variations in prosthesis height.

Progressive development of cracks in biochar–cement composites through multiscale analysis

Computer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract The intrinsic brittleness of the cement matrix limits its synergy with steel reinforcement bars, constraining energy dissipation and crack control capacity of concrete. Enhancing the ductility of cementitious materials is, therefore, essential for improving structural resilience.

The oral microbiota and periodontal health in orthodontic patients

Periodontology 2000, EarlyView.
Abstract The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years‐of‐age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity.
