Clinical Evaluation of Hybrid Ceramic Occlusal Veneers Bonded With Two Self Adhesive Resin Cements

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).
