Clinical Trial Summary

Alveolar bone resorption often occurs after tooth extraction. At present, guided bone regeneration technique is widely used in clinic since it leads to less trauma and less complications. Tenting screw technology, basic on the classical GBR, implants screws into the surgical area to prevent the barrier membrane from collapsing. Moreover, advanced platelet rich fibrin and injectable platelet-rich fibrin are used to provide the osteogenic function. The investigators intend to increase vertical alveolar bone augmentation by combining tenting screws and A-PRF, I-PRF.
