This randomized clinical trial aims to evaluate the clinical performance of hybrid ceramic occlusal veneers cemented with two different bonding protocols: a self-adhesive bonding protocol with adhesive enhancement (BeautiLink SA cement with BeautiBond Xtreme adhesive) versus another self-adhesive bonding protocol (RelyX U200 self-adhesive resin cement with 3M UNIVERSAL bond).
