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

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-CaSiO 3 coating on PolyEtherEtherKetone (PEEK) implants using the electrospray technique. The study includes control PEEK disks and experimental groups with different coatings: Zein-CaSiO 3 , Zein, and CaSiO 3 . 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 CaSiO 3 ) 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-CaSiO 3 ) coating on PEEK dental implants is a promising option for enhanced implant performance.
