Introduction: Alveolar reconstruction of vertical bone defects remains a daunting challenge in implant dentistry. Among the various techniques used to correct such defects is distraction osteogenesis (DO), which has been described as a technique used to gain bone and soft tissues, especially in surgeries for reconstruction of mandibular and maxillary alveolar ridges to allow the placement of dental implants in a favorable position and with greater success predictability when subjected to functional loads. Objective: The purpose of this study was to evaluate the effectiveness of DO in two patients treated with the technique of alveolar distraction osteogenesis. Case report: The clinical cases were evaluated for bone gain through clinical and radiographic examination, pre- and post-distraction. Results: At the end of treatment, both cases had gained sufficient bone as to enable subsequent rehabilitation with implants. Conclusions: The success rate reported in the literature and in the cases presented here prove the efficiency of the technique and its clinical feasibility.
