Electrospray coating of poly ether ether ketone (PEEK) dental implant material with Zein-CaSiO₃ composite

Abstract

Dental implants, coated with materials, are strategically implanted in the bones, serving a vital function in accelerating healing and promoting bone regeneration in the vicinty of implants. Applying a polymer matrix as a coating material emerges as a promising approach for enhancing the properties of these implants. This research investigates the impact of Zein-CaSiO3 coating on PolyEtherEtherKetone (PEEK) implants using the electrospray technique. The study includes control PEEK disks and experimental groups with different coatings: Zein-CaSiO3, Zein, and CaSiO3. Characterization involved techniques such as atomic force microscopy to evaluate the surface topography of the composite coating, scanning electron microscopy (FE-SEM) was employed to analyze the morphology of surface, water contact angle, and adhesion test. Group 3 (PEEK coated with CaSiO3) exhibited the lowest water contact angle in comparison to the control group, Also there were present an increasing in adhesion strength to the substrate with the groups 1 (PEEK coated with zein-CaSiO3) and 2 (PEEK coated with zein) compared to Group 3. This study suggests that the electrospraying of (Zein-CaSiO3) coating on PEEK dental implants is a promising option for enhanced implant performance.
