What this trial studies

This study compares two bone graft materials, freeze-dried bone allograft (FDBA) and collagen-enriched bovine xenograft (CEBX), used for preserving bone after the extraction of an anterior tooth before dental implant placement. Patients will be randomly assigned to receive either FDBA or CEBX, and the study will evaluate differences in ridge dimensional changes, clinical outcomes, and patient satisfaction over a 16-week healing period. The study includes multiple visits and utilizes advanced imaging techniques to assess the effectiveness of each graft material.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who require extraction of an anterior tooth and seek dental implant replacement.

Not a fit: Patients who smoke, have uncontrolled diabetes, or are on certain medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the outcomes of dental implant procedures by identifying the more effective bone graft material.

How similar studies have performed: Previous studies have shown varying success with different bone graft materials, making this a relevant comparison in the field.
