Peek material hardness12/27/2023 ![]() It has become the main driver of dental treatment and the centerpiece of dental science with the rise of human welfare, standard of living, and the increased level of oral health awareness. Prosthodontics is a major branch of dental medicine. On the basis of the obtained results, PEEK/SiO 2 nanocomposites loaded with low content hydrophobic nano-SiO 2 are recommended as promising candidates for orthopedic and prosthodontics materials. The addition of nano-SiO 2 fillers in a higher weight percentage, over 10%, significantly damages the mechanical characteristics of the resultant nanocomposite. The introduction of 10 wt% of hydrophobic nano-SiO 2 to the PEEK matrix improved elastic modulus, flexural strength, and microhardness, according to the findings. SEM images revealed that nanocomposites filled with low content hydrophobic nano-SiO 2 showed uniform dispersion within the PEEK matrix. All nanocomposites showed increased surface roughness compared to pure PEEK. Mechanical properties were measured by microhardness, elastic compression modulus, and flexural strength. The crystalline structures of PEEK/SiO 2 nanocomposites were examined by X-ray diffraction (XRD) spectroscopy. The influence of nano-SiO 2 type and content (10, 20 and 30% wt) on surface properties of the resultant nanocomposites was investigated by the use of scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), surface roughness analysis, and contact angle measurement. In this work, PEEK based nanocomposites containing hydrophilic or hydrophobic nano-silica were prepared by a compression molding technique. ![]() The aim of this research was to understand how different types and contents of nano-sized silica (SiO 2) fillers influenced the surface and mechanical properties of PEEK nanocomposites used in prosthodontics. For bonding with various adhesive agents and preserved teeth, the surface alteration of PEEK was investigated. PEEK is being used more commonly to replace traditional dental products. ![]() In the field of orthopedics and traumatology, polyether ether ketone (PEEK) serves a significant role as a suitable alternative to traditional metal-based implants like titanium.
