**3.1 Clinical outcomes**

Bone augmentation with cortical bone wedges was performed in adult patients, mean age 47 years; ranging from 19 to 67 years. Different sites at the maxilla and the mandible had been treated with the WT, and the majority of the augmented sites were at the posterior mandible (**Figure 10**). The majority of the treated patients had more than one site to augment. The healing process was uneventful. The donor site for the bone block (the retromolar area) healed very well without complications and spontaneous regeneration of the site was observed during the follow-up period, with full regeneration after twelve months. The recipient sites healed very well, and the bone augmentations were maintained without wound dehiscence among almost all the treated patients. However, one patient experienced a partial breakdown of the wound, and the majority of the augmented bone was lost; this patient had completed treatment with nerve transposition for implant placement. Four months after the augmentation surgery, clinical evaluation of the recipient sites revealed new hard tissue volume and good ridge contour. CBCT evaluation showed a good bone volume with 4 to 8 mm bone gain horizontally and 3–6 mm bone gain vertically. The second surgery that was performed for dental implant placement revealed a new and good bone volume, with excellent integration of the bone wedges at the recipient site. The excellent integration of the bone wedges was obvious with no dislodgement during the implant site preparation. Dental implants were inserted of adequate lengths (10-16 mm) and diameters (2.8–4.2 mm). Further follow-up of the augmentation sites and the implants in both the mandible and the maxilla revealed stable long-term outcomes after the implants rehabilitation.
