What this trial studies

This study evaluates the effectiveness of allogenic dentin matrix versus autogenous partially demineralized dentin matrix in preserving ridge structure after tooth extraction in the aesthetic zone. Patients with unrestorable anterior teeth will undergo periodontal and radiographic examinations to assess their suitability for the study. Following tooth extraction, the two different types of dentin matrices will be applied, and their effects on hard tissue changes will be monitored through various measurements and follow-up visits. The goal is to determine which method better maintains bone structure and aesthetics post-extraction.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with unrestorable anterior teeth and no more than 50% buccal bone loss.

Not a fit: Patients with systemic conditions affecting healing, poor oral hygiene, or those who smoke may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve outcomes for patients undergoing tooth extractions by enhancing ridge preservation techniques.

How similar studies have performed: While similar approaches have been explored, this specific comparison of allogenic versus autogenous dentin in ridge preservation is relatively novel.
