Clinical Performance of Full Coverage Hybrid Ceramic Crowns in the Aesthetic Zone: A Randomized Clinical Trial

Direct benefit of the research to the human volunteer:

• Participants will receive high-quality dental restorations (hybrid ceramic full coverage restorations) fabricated using standardized protocols and materials.
• All participants will have their restorations placed by qualified dental professionals in a controlled clinical environment, ensuring proper technique and follow-up care.
• Participants will benefit from regular follow-up examinations at 6, 12, and 18 months, which allows for early detection and management of any potential issues with their restorations.
• Any issues or failures identified during the follow-up period will be documented and repaired at no additional cost to the participant.
• Participants will contribute to advancing dental knowledge regarding optimal hybrid ceramic materials, which may lead to improved treatment protocols and long-term outcomes for future dental patients.
• The research provides an opportunity for comprehensive oral health monitoring beyond just the restoration itself, potentially identifying other dental issues that might require attention.

The scientific interest and the desired public benefit of the research:

Scientific Interest

1. This research will help understanding the material-specific outcomes in terms of marginal adaptation, color match, retention, surface texture, and restoration failure
2. The study will contribute to the understanding of the relationship between laboratory findings and clinical outcomes for dental materials, particularly regarding hybrid ceramics.
3. The findings may generate evidence on the clinical effectiveness and long-term behavior of two hybrid ceramic materials
4. The research will provide long-term clinical data on modern dental materials, which is valuable for developing future materials and techniques.
5. The study evaluates how the properties of Beautilink SA self-adhesive resin cement interact with these crown materials to affect clinical outcomes, offering new insights into optimal cementation protocols.
