Characterization and Testing the properties of PEKK- Strontium- hydroxyapatite composite material

Abstract

Polymers, being one of the most important materials in dentistry, offer great physical and mechanical qualities, as well as good biocompatibility. Aim of this study was done to evaluate the Polyetherketoneketone and Polyetherketoneketone polymer composite material used as dental implant through tensile strength, Fourier Transform Infrared analysis FTIR, and wettability). Polyetherketoneketone composites (Polyetherketoneketone and Strontium-containing hydroxyapatite) with selected weight percentage ratios of (0, 10%, 20%, 30%), were fabricated using a compression molding technique”, The study involved Samples preparation (sheets) shaped and form into the desired shape according to standard for tests which included tensile strength, Fourier Transform Infrared analysis FTIR, and wettability. The results obtained from the experiments showed slight increase in tensile strength of the polymer composite consisting from polyetherketoneketone and strontium hydroxaptatite nanofiller compared with pure Polyetherketoneketone, with increase the in concentration of Polyetherketoneketone composite (concentration 10%, 20%, 30%), improvement in the wettability value, with no effect in the chemical structure of Polyetherketoneketone composite comparing with the PEKK composite.

Fabrication and characterization of bioactive composite: A pilot study

“…The findings reveal the same absorption bands of PEKK before and after compression. 12,43,44 Additionally, the crystallinity of PEKK after compression molding was reported as C-H out-ofplane bending substitution patterns observed at 1305, 1272, 985, and 920 cm À1 , where the intensity and width of the bending bands increased, which is consistent with the increased polymerization and structural order. 45 In living systems, all bioactive substances form an apatite layer that resembles bone on their surfaces and can bind to the bone through this layer.…”

“…11 Bioactive materials can be created by modifying the PEKK surface through physical and chemical methods, or scaffolding. The incorporation of ceramic materials is another method for producing bioactive composite materials 12 as inadequate osseoconductivity and bioactivity of dental implants may result in severe implant failure and implantitis 13…”

“…The results obtained from (Jani et al, 2022) showed increase in mechanical properties of nSr-HA/PEKK compared with un modified PEKK with no effect in the chemical structure. 12 In this study, bioactive materials are synthesized by combining an organic polymer (PEKK) with various percentages of bioactive CS microparticles via compression molding and selecting the optimum concentrations of these particles to be incorporated into the PEKK matrix based on the in vitro apatite-forming ability, flexural strength, and elastic modulus after considering the following proposed research hypotheses:1) The null hypothesis (H0) proposes that neither bioactivity nor mechanical properties are affected by the incorporation of CS into PEKK polymeric matrix.2) The alternative hypothesis (H1) assumes that the bioactivity and mechanical properties are enhanced after incorporating CS into PEKK polymeric matrix.…”
