What this trial studies

This clinical trial investigates the effectiveness of concentrated growth factors (CGF) in preserving and regenerating soft and hard tissues during tooth extraction site preservation surgery. A total of 20 patients will be randomly assigned to four different treatment groups, each receiving various combinations of bone powder, collagen membranes, and CGF. The study aims to evaluate outcomes such as pain levels, wound healing, and changes in gingival and alveolar dimensions over a follow-up period of more than six months. The same physician will perform all surgeries to ensure consistency in the procedure.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 25 to 45 who require tooth extraction and are willing to undergo site preservation without systemic diseases affecting healing.

Not a fit: Patients with serious systemic diseases like diabetes or hypertension, or those outside the age range of 25 to 45, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance healing and tissue preservation after tooth extractions, leading to better long-term dental outcomes.

How similar studies have performed: While the use of CGF in dental procedures is gaining interest, this specific application in extraction site preservation is relatively novel and has not been extensively tested in prior studies.

Eligibility criteria
