Background: Polyetheretherketone (PEEK) is a material that can be used instead of normal titanium implants. PEEK is considered inert and biocompatible, however, it has been shown to possess low surface energy and that leads to decreased osteointegration with bone, Recent researches have focused on increasing the bioactivity of PEEK by modifying the surface by chemical and physical means such as plasma treated surfaces. The Purpose of this article to evaluate peek dental implant with cold plasma surface treatment Materials In this case series an immediately loaded peek dental implant, treated with plasma surface activation method, was used to replace anterior teeth in maxilla , for 30 patient, and followed up for 12 months. The results: All 30 implants placed survived the 12 month follow-up. Conclusion: In this case series PEEK dental implant with cold plasma surface treatment showed high survival rate after using plasma treatment surface methods
