Fused deposition modeling (FDM) is a rapidly growing three-dimensional (3D) printing technology and has great potential in medicine. Polyether-ether-ketone (PEEK) biocompatible high-performance polymer, which suitable to be used as an orthopedic/dental implant material. However, the mechanical properties biocompatibility of FDM-printed PEEK its composites are still not clear. In this study, pure carbon fiber reinforced (CFR-PEEK) composite were successfully fabricated by FDM characterized...
Cobalt-chromium (Co-Cr) alloy is a widely used base material for dental fixed prostheses. These restorations can be produced through casting technique, subtractive or additive manufacturing technologies. However, limited information available regarding the influence of techniques on properties Co-Cr since most studies different chemical compositions methods. This study compares mechanical properties, metal-ceramic bond strength, and microstructures specimens by casting, milling, selective...
Polyetheretherketone (PEEK) is a prime candidate to replace metallic implants and prostheses in orthopedic, spine cranio-maxillofacial surgeries. Fused-filament fabrication (FFF) an economical efficient three-dimensional (3D) printing method fabricate PEEK implants. However, studies pertaining the bioactivity of FFF 3D printed are still lacking. In this study, samples were fabricated modified with polishing grit-blasting (three alumina sizes: 50, 120, 250 µm) achieve varying levels surface...
Polyetheretherketone (PEEK), a biomaterial with appropriate bone-like mechanical properties and excellent biocompatibility, is widely applied in cranio-maxillofacial dental applications. However, the lack of antibacterial effect an essential drawback PEEK material might lead to infection osseointegration issues. This study aims apply natural agent, totarol coating onto 3D printed surface find optimized concentration balanced cytocompatibility, osteogenesis, capability.
The objective of this study was to determine the effect two plasma surface treatments on biologic responses PEEK medical implants manufactured by fused filament fabrication (FFF) 3D printing technology.This created standard samples using an FFF printer. After fabrication, half were polished simulate a smooth surface. Then, argon (Ar) or oxygen (O2) used modify bioactivity printed and samples. Scanning electron microscopy (SEM) profilometer microstructure roughness sample surfaces....
Zinc (Zn) and Zn-based alloys have been proposed as a new generation of absorbable metals mainly owing to the moderate degradation behavior zinc between magnesium iron. Nonetheless, mechanical strength pure Zn is relatively poor, making it insufficient for majority clinical applications. In this study, novel Zn–2Ag–1.8Au–0.2V (wt.%) alloy (Zn–Ag–Au–V) was fabricated investigated use potential biocompatible material. Microstructural characterization indicated an effective grain-refining...
Three-dimensionally printed polyetheretherketone (PEEK) materials are promising for fabricating customized dental abutments. This study aimed to investigate the adhesive property of a 3D-printed PEEK material. The effects surface treatment and temporary crown on shear bond strength were evaluated. A total 108 discs 3D by fused-filament fabrication. Surface treatments, including sandblasting, abrasive paper grinding, CO2 laser ablation, applied discs, with untreated specimens set as control....
Background Nowadays, peri-implantitis, a destructive inflammatory process around implants contributing to bone loss, has become the main reason for implant failure. Bacterial colonization and subsequent plaque formation on surface is one of factors causing peri-implantitis. Totarol kind natural biocompatible antibacterial agent, with bactericidal effect towards wide range gram-positive, even antibiotic-resistant bacteria, including methicillin-resistant S. aureus. Aim/Hypothesis This in...
