The periapical and panoramic radiographic analysis showed a radiolucency image on the related teeth which were previously applied endodontic treatment [Figure 1].

Sinus augmentation was applied in the 3rd month after the FGG, which reduced to 22 mm x 4 mm in the 3rd month [Figure 2].

FDBA was positioned around the implants, filling completely in the defect [Figure 4b and d]. Finally, the d-PTFE membranes were completely fixed with buccal pin [Figure 4e].
