What this trial studies

This clinical trial involves two groups of patients with a deficient maxillary alveolar ridge and a pneumatized sinus who require dental implants. One group will undergo open sinus lifting using autogenous bone mixed with bone marrow aspirate concentrate from the maxillary tuberosity, while the other group will receive a mixture of autogenous bone and bovine bone. The procedure will be performed under local anesthesia, and patients will be monitored for six months post-operation to evaluate bone regeneration and implant success. The study aims to determine the effectiveness of using bone marrow aspirate concentrate in enhancing bone quality for dental implants.

Who should consider this trial

Good fit: Ideal candidates are patients with missing maxillary teeth, a pneumatized sinus, and remaining bone height of less than 5mm.

Not a fit: Patients who smoke, are pregnant, or have medical conditions that contraindicate surgical procedures may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve bone regeneration and increase the success rate of dental implants in patients with maxillary deficiencies.

How similar studies have performed: While similar studies have explored various augmentation techniques, the specific combination of bone marrow aspirate concentrate and bovine bone in this context is relatively novel.
