Clinical Trial 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.


Description:

Recently, a systematic review demonstrated the effectiveness of synthetic bone materials, including biphasic calcium phosphate (BCP), as substitutes for autogenous bone. BCP consists of hydroxyapatite (HA) and β-tricalcium phosphate (β-TCP). In contrast with stable HA, β-TCP is highly resorptive and is replaced by newly formed bone; therefore, the resorption rate of BCP could be influenced by the ratio of HA and β-TCP. platelet-rich fibrin (PRF) was recently introduced as additional or replacement materials in bone augmentation procedures. The use of biologic mediators with osteoinductive properties has been considered to reduce the time interval and accelerate the formation of new bone. The strengths of PRF in reducing tissue inflammation, promoting the vascularization of bone tissue, accelerating new bone formation, and improving scaffold mechanics have been reported.
