Biphasic Material With PRF in Lateral Sinus Floor Augmentation

• Status: Not yet recruiting
• Trial end date: 2024-04-01
• Target enrollment: 0
• Participant gender: All

Summary

A lack of bone in the posterior maxilla, mainly resulting from the combination of alveolar bone resorption after tooth loss, pneumatization of the maxillary sinus, and periodontal disease, leads to increased difficulty during dental implant treatment.

The classic technique for maxillary sinus floor augmentation entails the preparation of the trap door to elevate the schneiderian membrane in the lateral sinus wall. it can be done either in a single stage with simultaneous implant placement or in two stages with delayed implant placement, depending on the available residual alveolar ridge height that necessary for implant primary stability.

The new compartment created between the floor of maxillary sinus and the elevated membrane was filled with either autogenous, allografts, xenograft or combination of them to maintain space for new bone formation. The disadvantages of such methods are high costs for grafting material, time consuming and high morbidity, because harvesting of bone grafts is needed.
