Comparing two methods for preserving bone after tooth extraction

Evaluation of Post Extraction Hard Tissue Alteration Following Ridge Preservation in the Esthetic Zone Using Allogeneic Dentin Matrix Versus Demineralized Freeze-Dried Bone Allograft: A Randomized Controlled Clinical Trial

NA · Cairo University · NCT06318650

This study is testing whether using two different types of bone grafts after tooth extraction helps preserve the jawbone better in patients needing dental work in the front of their mouth.

What this trial studies

This study evaluates the differences in clinical, radiographic, and histomorphometrical outcomes between using Allogenic Demineralized Dentin Matrix and Demineralized Freeze-Dried Bone Allograft (DFDBA) for alveolar ridge preservation following tooth extraction in the esthetic zone. Patients will undergo initial periodontal treatment before receiving either of the two graft materials during a flapless tooth extraction procedure. The study aims to determine which method is more effective in managing post-extraction hard tissue changes. Participants will be monitored for six months to assess the outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 20-55 with a single rooted, non-restorable tooth requiring extraction and minimal buccal bone loss.

Not a fit: Patients with uncontrolled systemic diseases, severe para-functional habits, or those who smoke may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve bone preservation techniques, leading to better outcomes for dental implants.

How similar studies have performed: Previous studies have shown varying success with similar grafting techniques, but this specific comparison is novel.
