What this trial studies

This randomized clinical trial compares the clinical performance of hybrid ceramic occlusal veneers cemented with two self-adhesive resin cement protocols: BeautiLink SA with BeautiBond Xtreme adhesive enhancement versus RelyX U200 with 3M UNIVERSAL bond. Adult participants with vital teeth and adequate tooth structure will be randomized to one of the two cementation protocols and receive occlusal veneers. Patients will be followed at scheduled intervals to record clinical outcomes and any complications related to retention, marginal integrity, or material performance. The trial is conducted at the Faculty of Dentistry, Cairo University, using standard restorative and follow-up procedures.

Who should consider this trial

Good fit: Ideal candidates are adults 21 or older with vital teeth, sufficient tooth structure for veneer retention, adequate oral hygiene, and the ability to attend scheduled follow-up visits and provide informed consent.

Not a fit: Patients with active periodontal disease, severe parafunctional habits (such as confirmed bruxism), poor oral hygiene, pregnancy or nursing, uncontrolled systemic disease, known allergies to study materials, or those unable to comply with study requirements are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, this could lead to more reliable and longer-lasting adhesive restorations for adults with worn occlusal surfaces, possibly reducing the need for more invasive treatment.

How similar studies have performed: Similar cementation approaches have been studied in restorative dentistry with generally favorable short-term results, although long-term comparative data remain limited.
