Fig. 8: The graft was fixed with four miniscrews.
Fig. 9: The osseous graft was covered with a PRGF membrane and a barrier membrane for GBR.
Fig. 10: Sufficient horizontal ridge dimensions after a healing period of four months.
Fig. 11: The CBCT shortly before re-entry demonstrated a significant gain of bone volume after augmentation.
Fig. 12: After flap elevation, a good osseointegration and stabilisation of the autograft was noticed.
Fig. 13: After the fixation screws were removed, the four implants with a diameter of 3.75 mm and a length of 11.5 mm were inserted epicrestally without a surgical guide.
Fig. 14: After three months of submerged healing, a successful implant osseointegration without bone resorption was visible on the panoramic X-ray.
