The long-term success of dental implants depends not only on osseointegration but also on the establishment of a stable and healthy peri-implant soft tissue seal. Titanium is the most commonly used implant material, but biological and aesthetic limitations have led to the search for alternatives. Zirconia provides metal-free esthetics but with mechanical risks. Polyetheretherketone (PEEK) has emerged as a promising candidate due to its bone-like elastic modulus. However, the biological inertness of PEEK results in limited protein adsorption, cellular attachment, and tissue integration. Hence, surface modification strategies are required. Autologous platelet concentrates have attracted increasing attention as a biofunctional surface coating due to their sustained release of growth factors such as TGF-β, PDGF, and VEGF, which are known to induce gingival fibroblast proliferation, collagen synthesis, and soft tissue repair. This mini review aims to provide an overview of the current evidence regarding dental implant materials, implant surface modification strategies, and the potential role of platelet concentrates as a biofunctional coating for improving the biological performance of dental implants. The results indicate that platelet concentrates may represent a promising strategy to improve cellular responses and tissue healing around implant surfaces.
