Evaluating changes in jawbone after tooth extraction with different preservation methods

Dimensional Changes After Different Alveolar Ridge Preservation Techniques for Posterior Region: Randomized Controlled Trial

Not applicable Interventional University of Campinas, Brazil · NCT06081296

What this trial studies

This clinical trial aims to assess the dimensional changes in soft tissue and alveolar ridge following the extraction of premolar and molar teeth using various alveolar preservation techniques. Eighty participants will be randomly assigned to one of four groups: a control group with traditional closure, a group receiving a mixed free gingival graft, a group with a bone graft and mixed free gingival graft, and a group utilizing a bone graft with a titanium seal. Cone Beam Computed Tomography will be employed to measure bone tissue height before and after the procedures, allowing for a detailed comparison of the effectiveness of each method.

Who should consider this trial

Good fit: Ideal candidates include individuals over 18 years old in good systemic health requiring extraction of premolar or molar teeth with sufficient bone support.

Not a fit: Patients with periodontal disease, smokers, pregnant or lactating women, and those undergoing orthodontic treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve post-extraction outcomes and enhance the preservation of alveolar bone, leading to better dental restoration options for patients.

How similar studies have performed: Previous studies have shown promising results with various alveolar preservation techniques, indicating potential for success in this approach.
