Polyetheretherketone (PEEK) is growing in popularity WITH an increased interest in the use of polyether ether ketone (PEEK) for orthopedic and dental implant applications due to its elastic modulus close to that of bone, biocompatibility, and its radiolucent properties PEEK with high chemical resistance, radiolucency, mechanical characteristics compared to those of human bones. Aim of this study this study was done to evaluate the PEEK and PEEK composite dental implant through mechanical and morphological evaluation. PEEK composites (PEEK and SiC with selected weight percentage ratios of (0, 1.5%, 3%, 4.5%, 6%). were fabricated using a compounding by melt blending by (Internal Mixer) at 365ºC, 5min. technique, The study involved Samples preparation (sheets) cutting and machining into desire shapes according to ASTM standards,for mechanical tests which includes tensile strength,elastic modulus and flexural strength,physical tests which include DSC, TGA, FTIR. Morphological test that include SEM, and EDX mapping. The results obtained from the experiments showed that the tensile strength, elastic modulus and flexural strength polymer composite consisting from polyetheretherketone and Silicone Carbide nanofiller implant increased comparing with pure PEEK with better distribution of nano filler particles in PEEK composite (concentration 1.5%, 3%, 4.5%) in the scanning electron microscope examination and EDX mapping.
