Comparing demineralized dentin grafts and xenografts for dental implants in the esthetic zone

Clinical and Radiographic Evaluation of the Peri-implant Tissue Changes Around Early Placed Implants in the Esthetic Zone With Contour Augmentation Using Autogenous Partially Demineralized Dentin Graft Versus Xenograft: A RCT

Not applicable Interventional Cairo University · NCT06164353

This study is testing whether using a special type of tooth graft or a different kind of graft helps people with a missing tooth grow better bone around dental implants in the front of their mouth.

What this trial studies

This study investigates the effectiveness of partially demineralized dentin grafts compared to xenografts in promoting bone regeneration around dental implants in the esthetic zone. It focuses on patients with a single non-restorable tooth and a thin buccal plate of bone, assessing the potential for contour augmentation. The methodology involves using a collagen membrane to cover the grafts and evaluating their osteoinductive properties. The study aims to determine which graft type yields better outcomes in terms of bone formation and implant stability.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 20 and older with a single non-restorable tooth in the esthetic zone and a thin buccal plate of bone.

Not a fit: Patients with systemic diseases affecting bone healing, such as diabetes or Paget's disease, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve dental implant outcomes and aesthetic results for patients requiring bone augmentation.

How similar studies have performed: Previous studies have shown promising results with demineralized dentin grafts, indicating potential for success in this approach.
