Composites made of polyetheretherketone (PEEK) are biocompatible materials that solve the aesthetic and allergy issues with titanium dental implants. PEEK matrix materials utilized in modern composites reinforced with plant-based organic fibers should not only be highly performant but also have good surface wettability and adhesion qualities. This work describes the wetting behavior and adhesion characteristics of PEEK augmented with phyto-based nanoparticles. The study used a phyto-based nanoparticle at various weight percentages (Group 1- 10% Filled PEEK, Group 2-20% Filled PEEK, and Group 3-30% Filled PEEK) to assess the contact angle value and its impact on the wettability and adhesion of various reinforced PEEK specimens. Group 1 showed the greatest advancing (74.86) and average (68.74) values, while Group 3 indicated the lowest advancing (67.47) and receding (49.83) contact angle values. A statistically significant difference in contact angle was found between the reinforced PEEK groups. The reinforced PEEK used in this work has enhanced wettability, allowing for further investigation into its mechanical and biological qualities for usage as a substitute for metallic implants without compromising its favorable bulk features. It has been found that the hydrophobic properties of the pure PEEK matrix can be altered with the addition of the phyto-based nanoparticle
