In order to achieve functional and esthetic oral rehabilitations, dental implants must be placed at an ideal tridimensional position in the alveolar bone. A clinical case is presented of a 49-year-old female with a severely resorbed pre-maxilla. Bone augmentation was conducted using the "tent pole" technique with human recombinant morphogenetic bone protein-2 embedded in an absorbable collagen sponge and deproteinized bovine bone. In addition, a titanium mesh was adapted over the graft to provide support. At 8 months postop, a cone beam computerized tomography (CBCT) scan showed significant bone consolidation. An ideal premaxilla ridge with more than 14 mm of vertical and 10 mm of horizontal width was observed. Four dental implants were placed. Re-entry was 6 months later. Individual crowns were made to substitute the incisors, which were in function for the 1-year follow-up.
