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

Not Applicable

Recruiting

• Conditions: Occlusal Wear of Teeth

• Registration Number: NCT07017062
• Lead Sponsor: Cairo University

Brief Summary

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).
