Best cementation method and materials for long-lasting front-tooth veneers
Official title: Adhesive Cementation Materials and Techniques in Aesthetic Dentistry and Their Effect on the Longevity of Porcelain Veneers
Run by Riga Stradins University · NCT07491809 · Data updated 2026-11-12
This trial tests two resin cements and compares direct versus indirect restorations to see which gives longer-lasting, less discolored front-tooth veneers for adults needing at least four upper veneers.

Is this trial a fit for you?
✓Likely a good fit
Adults with healthy periodontium, stable occlusion, good oral hygiene, and at least four maxillary anterior teeth suitable for enamel-bonded veneers are ideal candidates.
✕Probably not a fit
Patients with heavy bruxism, poor oral hygiene, active periodontal inflammation, or insufficient enamel at the veneer margins are unlikely to benefit and are excluded.

What this trial studies
About 30 patients at Riga Stradins University's Prosthodontics department who need at least four maxillary anterior veneers will be enrolled. Porcelain veneers will be prepared with approximately 0.5 mm facial reduction and cemented using either Panavia Veneer LC or Panavia V5, with direct composite restorations included for comparison. Outcomes include marginal defects and discoloration of the veneers and patient-reported aesthetic satisfaction measured by the Orofacial Esthetic Scale at 1- and 3-year follow-ups. Patients with heavy bruxism, poor oral hygiene, or active periodontal disease are excluded to ensure adequate enamel margins and healing potential.
Why it matters
Potential benefit: If successful, this work could lead to veneers that stay better sealed, resist staining longer, and give patients higher aesthetic satisfaction with fewer repairs.
How similar studies have gone: Previous comparisons of adhesive resin systems and veneer techniques have produced mixed results; Panavia cements are well-established clinically but direct head-to-head long-term data are limited.
