Polyaryletherketone (PAEK) polymers, including polyetheretherketone (PEEK) and polyetherketoneketone (PEKK), are increasingly used in prosthodontics because of their favorable mechanical and biological properties. However, their chemically inert and low–surface-energy characteristics result in insufficient bonding to veneering composite resins. Therefore, effective and clinically safe surface treatment protocols are required to enhance adhesion. Square specimens were fabricated from three Comput
