Fabrication and characterization of PEKK nanocomposites: An in vitro study.

Although the number of implants has increased gradually and consistently over the years to around one million per year globally, there is still far more potential for advancement in the field of dental implantology which is typically growing quickly. This study investigates the effect of nanofiller reinforcement high-performance polymer matrix to enhance mechanical and physical characteristics. Calcium silicate (CS)/Polyetherketoneketone (PEKK) biomedical composite (G0 as a control group) is reinforced with different weight percentages (G1-G4) of tellurium dioxide nanoparticles (TeO2 NPs) (n = 5). This research uses ethanol as a binder for mixing various weight percentages (wt%) of TeO2 NPs with CS/PEKK biomedical composite. The combination is then dried at 120°C in a forced convection oven before being put into special molds and compressed for 20 min Holding period at 310°C and 15 MPa. The composites were prepared via the compression molding technique. Morphological, mechanical, and physical characteristics were studied. The findings of this study suggested improvement in the interfacial interaction between TeO2 NPs (G1 and G2) and CS/PEKK bioactive composite resulting in better mechanical and physical properties, especially at 1 w% of TeO2 NPs (G2).
