Rebuilding bone in the lower back jaw with resorbable or non‑resorbable membranes

Comparative Evaluation of Resorbable (Pericardium) Versus Non Resorbable (Polytetrafluoroethylene) Membrane for Horizontal Bone Augmentation of Posterior Atrophic Mandible

Not applicable Interventional Beirut Arab University · NCT07254494

This trial tests whether a resorbable pericardium membrane or a non‑resorbable PTFE membrane better helps rebuild horizontal bone in the lower back jaw for people who need bone grafting before dental implants.

What this trial studies

Adults with horizontal bone loss in the posterior mandible will receive guided bone regeneration using either a resorbable pericardium membrane or a non‑resorbable PTFE membrane along with standard graft material. Outcomes such as horizontal bone gain, membrane exposure, infection, and readiness for implant placement will be tracked over follow‑up visits extending at least one year. The procedures follow routine surgical protocols for ridge augmentation and include perioperative care to minimize complications. Data will be compared between the two membrane groups to see which approach provides more predictable horizontal bone reconstruction.

Who should consider this trial

Good fit: Adults with an atrophic posterior mandibular alveolar ridge needing horizontal bone augmentation before implant placement, who have adequate residual bone height, good oral hygiene, and no systemic conditions that impair bone healing are ideal candidates.

Not a fit: Patients with vertical or complex defects, active local or systemic infections, heavy smokers, poor oral hygiene, pregnancy, or systemic diseases affecting bone healing are unlikely to benefit from this comparison.

Why it matters

Potential benefit: If successful, the better membrane option could provide more reliable horizontal bone gain and fewer complications, making implant placement easier and more predictable.

How similar studies have performed: Previous studies show both PTFE and resorbable membranes can support guided bone regeneration, with PTFE offering strong space maintenance but higher exposure and removal needs while resorbable pericardium often has fewer exposures, although direct head‑to‑head evidence is still limited.
