Comparing two types of membranes for bone regeneration after tooth extraction

Official title: A Randomized Controlled Trial Comparing Titanium Reinforced d-PTFE Membrane to Collagen Membrane for Guided Bone Regeneration at Single Tooth Sites in the Premaxilla: a Clinical, CBCT and Histomorphometric Analysis

Run by University Ghent · NCT05426616 · Data updated 2026-11-12

This study tests which type of membrane works better for helping patients grow new bone after having a tooth pulled, so they can get dental implants later.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients who have had a tooth extracted at least three months prior and have a single tooth gap in the anterior maxilla with good oral hygiene.

Probably not a fit

Patients with systemic diseases, a history of smoking or periodontal disease, untreated caries, or those who are pregnant may not benefit from this study.

What this trial studies

This clinical trial investigates the effectiveness of two different membranes, a resorbable collagen membrane and a titanium reinforced d-PTFE membrane, in guided bone regeneration for patients needing dental implants after tooth extraction. Participants must have a single tooth gap in the anterior maxilla and sufficient oral hygiene. The study aims to measure changes in bone dimensions following the application of these membranes in conjunction with a combination of xenogenous and autologous bone. The goal is to determine which membrane provides better outcomes for bone volume restoration.

Why it matters

Potential benefit: If successful, this study could improve the success rate of dental implants by optimizing bone regeneration techniques.

How similar studies have gone: Previous studies have shown varying success with guided bone regeneration techniques, but this specific comparison of membrane types is relatively novel.
