Resumo: Vertical alveolar bone atrophy represents a challenge for reconstruction, especially when the esthetic zone of the maxilla is involved. When reconstruction is not achieved, a good esthetic outcome is rarely obtained. The aim of this retrospective study was to asses the outcome of implant-bone block movement, after segmental osteotomy in the maxillary aesthetic region in patients with vertical alveolar bone atrophy. Patients with vertical alveolar bone atrophy who underwent repositioning of the bone-implant block segment in the maxillary aesthetic region with a minimum of 6 months of follow-up were selected. Outcome measures were the success rate of the implant, complications after the surgical procedure, amount of vertical bone augmentation, papilla formation, keratinized mucosal band height and patient satisfaction analysis. Nine patients were included in the study, all with multiple implants, totaling 25 implants. The mean vertical bone augmentation was 4.9 mm (3.0-8.4 mm), and only 1 implant failure occurred. A statistically significant improvement in papilla formation was observed after surgery, leading to a good aesthetic result. More than 2 mm of height of keratinized mucosa was observed in 6 patients, and also a high satisfaction and acceptance to the treatment. After data evaluation, it was concluded that the technique presented can reconstruct vertical alveolar bone atrophy, with a high implant survival rate in a short period of follow-up, improving the aesthetic-functional result with a good acceptance by the Patients
