Comparing two types of membranes for bone regeneration after tooth extraction

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

Not applicable Interventional University Ghent · NCT05426616

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.

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.

Who should consider this trial

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.

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.

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