Abstract

An adequate bone volume is mandatory for a favorable long-term prognosis in patients treated with dental implants. The vertical deficiency of posterior mandible is a common condition in partially edentulous patients, in which vertical bone augmentation procedures or inferior alveolar nerve transposition become necessary for the dental implant rehabilitation. Thus, the aim of this study was to discuss options of vertical bone augmentation techniques in atrophic posterior mandibles and to present, as case reports, alternatives for the rehabilitation of patients with this condition. So, three alternatives of treatment were presented: the use of Cytoplast titanium-reinforced membrane over autogenous and xenogenous particulate bone graft; sandwich osteotomy; and nerve transposition. In the three reported cases, the chosen surgical techniques showed to be appropriated and allowed the placement of longer implants. No significant complications were observed and all the patients were satisfied with the performed treatment. It is possible to conclude that the reconstruction of atrophic posterior mandible remains a challenge to the professionals, who must know the various existing techniques and choose the most suitable one to each patient.
