The percentage of titanium incorporation into PEEK should not cause any inflammation or fibrous tissue deposition it should also be adjusted in a way to produce enhanced hydrophilic reactions so that more cellular proliferation is guaranteed through enhanced wettability. Other surface modification methods include plasma spraying/coating/immersion, electron beam deposition and ion vapor deposition. Poly Ether Ether Ketone (PEEK) is a high-performance polymer which has proven to be successful in many areas of medicine. The modification involves incorporating nanoparticles of TiO2, HAF or HAp through melt-blending process to achieve bioactive nanocomposite with high tensile strength and osteoconductivity. There is a current trend toward using titanium-reinforced PEEK abutments to gain the strength properties from titanium and biocompatibility from PEEK. It has so far been used as healing/provisional abutment and it is promising to be used as final abutment. Poly ether ether ketone (PEEK) is one such material that finds popular use in Prosthodontics. Although acrylic resins were introduced to dentistry in 1937 following which various materials have also been introduced in material science, none of them. It is one of the most biocompatible dental materials available in the market at present and has shown minimal post-prosthodontic treatment complications. The questions whether the PEEK framework has similar stress distribution on oral tissue. Evolution of scientific knowledge has brought forth numerous materials in Prosthetic dentistry. Another major advantage of PEEK is the fact that it exhibits stress/strain properties almost similar to the bone. Polyetheretherketone (PEEK) is a new material used for the frameworks of removable partial dentures (RPD). In dentistry, PEEK is believed to provide more aesthetic, purpose-specific appearance than titanium with almost similar hard and soft tissues’ responses. It has been considered as an alternative for metallic components of orthopedic implants as it induces low sensitivity reactions and less artifact with imaging. PEEK is a dominant of PAEK (poly-aryl-ether-ketone) polymers that possess high thermal stability (>300 ☌) and mechanical/chemical resistance in addition to low density (1.32 g/cm3), solubility and elastic modulus (3–4 GPa). PEEK has a high strength to weight ratio and. PEKK biomaterials is an elastic material with good shock absorbance and fracture resistance and present ultra-high performance among all thermoplastic composites for excellent mechanical strength, chemical resistance, and high thermal stability. There is current research on reinforcing PEEK material by additives and surface modifications. PEEK is a medical grade polymer that provides patients with an alternative solution to chrome cobalt dentures. It can be applied in dental implants as implant superstructure, abutment or body. PEEK (polyetheretherketone) is a semi-crystalline linear polycyclic thermoplastic material which is considered as a strong biomaterial.
