Vertical defect in the front maxilla (more than 10mm) as consequence of a failed implant treatment. Bone was harvested from the external oblique line of the right mandible (applying the Safecut procedure) and grafted vertically (following the protocol proposed by Khoury). 4-month post augmentation implant was inserted and an overbuilding was created by adding bovine bone covered with a collagen membrane. After 4 months the second stage implant surgery was done adding a connective tissue graft.
