Six months after surgery, radiological examinations were carried out and the patient underwent implant placement (Fig. 4). The postoperative bone height had increased to 10.1 mm at position 26 and 12.9 mm at position 27 compared with the preoperative heights of 6.1 and 7.5 mm, respectively. Postoperative clearance was reduced by 11 mm compared with the preoperative clearance. Careful separation of the mucoperiosteum revealed that the fixation device was in the right place, the interpositional bone graft had been incorporated, and gains in the height and thickness of the alveolar ridge had been achieved. The fixation system was removed, and two dental implants (4.5 × 11 mm) (Astra Tech AB, Mölndal, Sweden) were placed in accordance with the original treatment protocol under the relevant surgical guidance (Fig. 5). Three months after implant surgery, the temporary prosthesis was fixed, and after a further 3 months, the final prosthesis was fixed (Fig. 6). The postoperative course was uneventful for 9 years after surgery (Fig. 7).
