What this trial studies

This clinical trial investigates the effectiveness of two different socket seal techniques for preserving alveolar bone following tooth extraction. Participants will be randomly assigned to one of three groups: one receiving standard suturing, another receiving a free gingival graft, and the third using a polylactic-glycolic acid membrane. The primary focus is on measuring changes in alveolar bone height and width, as well as other secondary outcomes related to tissue healing. The goal is to determine which method best stabilizes the blood clot and minimizes bone resorption.

Who should consider this trial

Good fit: Ideal candidates are individuals requiring a single tooth extraction with less than 50% periodontal destruction.

Not a fit: Patients with systemic diseases affecting wound healing or those requiring multiple extractions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved techniques for preserving alveolar bone, enhancing outcomes for dental implant placements.

How similar studies have performed: Previous studies have shown varying degrees of success with similar socket preservation techniques, indicating potential for positive outcomes.
