Abstract: Polyetheretherketone (PEEK) is a high-performance specialty plastic with good mechanical properties and biocompatibility and is easy to process and form, making it an alternative material for dental implants. However, the lack of biological activity and the easy accumulation of plaque limit the clinical application of PEEK in the field of oral implantology. At present, many scholars solve the problem of biological inertia and plaque attachment of PEEK through trace elements modification. Different trace elements have their own advantages. Strontium, tantalum, manganese, and other elements can promote osteoblast differentiation. Fluorine, silver, zinc, and other elements can inhibit the growth of inflammatory bacteria, and the co-modification of various trace elements gives PEEK implant more diversified properties.
