Comparing two bone grafts to preserve the socket after tooth extraction

Comparative Analysis of Healing Outcomes Between Two Bone Graft Materials in Socket Preservation Procedure

Not applicable Interventional Pharos University in Alexandria · NCT07344025

This test will compare an allograft and a bovine xenograft to see which better preserves jaw bone and gum shape after tooth extraction in healthy adults aged 21–50.

What this trial studies

Patients needing socket preservation after tooth extraction will be recruited from the Pharos University College of Dentistry outpatient clinic and must be systemically healthy non-smokers with good oral hygiene. Preoperative CBCT scans and fabricated reference stents will provide standardized baseline measurements of bone dimensions. Socket preservation procedures will be performed under local anesthesia using either an allograft or a bovine xenograft, with clinical measurements and histologic samples collected after 2–3 months of healing. Outcomes will compare dimensional bone changes and histologic bone formation between the two graft materials.

Who should consider this trial

Good fit: Healthy, non-smoking adults aged 21–50 who need tooth extraction and socket preservation, have good oral hygiene, and no conditions or medications affecting bone metabolism.

Not a fit: Patients with advanced periodontitis, active infection, severely resorbed sockets (buccal bone height <5 mm), heavy smokers, pregnant patients, or those on bone‑affecting medications are unlikely to qualify or benefit.

Why it matters

Potential benefit: If successful, the better-performing graft could help maintain bone and gum contours after extraction, making future implant placement easier and more predictable.

How similar studies have performed: Previous research shows both allografts and bovine xenografts can help preserve ridge dimensions, but direct head‑to‑head comparisons yield variable results.
