Brief summary: This randomized controlled trial evaluates the clinical performance of laminate veneers fabricated from HC hard blocks pretreated with BeautiBond Xtreme versus HC Primer, using BeautiLink SA cement. The study focuses on marginal adaptation, retention, discoloration, and recurrent caries over 18 months.

Detailed description: This clinical trial compares two bonding protocols for hybrid ceramic laminate veneers. The veneers are fabricated from HC hard blocks and bonded using BeautiLink SA resin cement. One group receives BeautiBond Xtreme pretreatment, while the other receives HC Primer. The study assesses marginal adaptation, retention, recurrent caries, and discoloration over 18 months to determine the superior clinical bonding protocol for these restorations.

Eligibility criteria: Inclusion Criteria:dult patients ≥ 21 years requiring laminate veneers in the esthetic zone, vital or endodontically treated teeth, sufficient enamel, willing and able to consent and comply.

-

Exclusion Criteria: Periodontal disease, bruxism, poor hygiene, pregnancy, systemic illness, allergies, insufficient enamel, ongoing trials, orthodontic treatment.
