Improving soft tissue around dental implants using two methods

Evaluation of Xenogeneic Collagen Matrix Versus Connective Tissue Graft to Enhance Soft Tissue Profile Around Single Dental Implants in the Aesthetic Zone

NA · Damascus University · NCT06837688

What this trial studies

This clinical trial compares the effectiveness of two techniques for enhancing soft tissue around dental implants in the aesthetic zone of the anterior maxilla. It involves 30 adult patients with a single missing tooth who will be randomly assigned to receive either an autogenous connective tissue graft or a xenogeneic collagen matrix. The study employs a fully digital workflow for precise implant planning and placement, utilizing advanced imaging and CAD/CAM technology. The primary goal is to assess the increase in buccal soft tissue thickness following the procedures.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 or older with a single missing tooth in the aesthetic zone and sufficient bone and keratinized tissue.

Not a fit: Patients with systemic diseases, smoking habits, periodontal disease, or those requiring additional bone augmentation may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a less invasive and effective method for improving soft tissue aesthetics around dental implants.

How similar studies have performed: Previous studies have shown promising results with similar soft tissue augmentation techniques, indicating potential for success in this approach.
