case_images: Clinical examinations showed the absence of anterior maxillary tooth [Figure 1a]. After elevating the graft from the donor site, it was stored in a mixture of saline and the patient's blood, with addition of 80 mg gentamicin [Figure 1b and c]. One or two screws of diameter 1.5 mm were used (1.5 mm x 8 mm, titanium, Orthomax) to stabilize the bone block graft at recipient site [Figure 1d]. The fibrin clot was removed with the use of a surgical pincer, then separated from the red blood cells with the use of scissors, and then compressed to be used as a PRF membrane [Figure 1e and f].

case_images: Cone-beam computed tomography (CBCT) scan showed an increase in bone width from 1.8 to 4.1 mm at the alveolar crest [Figure 2a and b]. The implant was provided with cover screw [Figure 2c].

case_images: In the 10th postoperative month, a periapical radiograph was obtained to evaluate the osseointegration of the implant [Figure 3a]. After stabilization of gingival tissues, implant level impression was made using open tray impression coping (SKY Bredent), and a master cast was fabricated with implant body analogs [Figure 3b-d]. The metal porcelain crowns were finished and cemented on to the implants using glass ionomer cement (Gc Gold Label 1) [Figure 3e-g].
