A case report and description of a new technique for bone morphogenetic protein-2 augmentation of the maxilla are provided here. Horizontal maxillary atrophy was treated with a full-arch alveolar split osteotomy combined with sinus floor intrusion. The defect was grafted with bone morphogenetic protein-2 and demineralized freeze-dried bone allograft. Nine months later, a transgingival approach was used to place dental implants and a prefabricated provisional denture. The provisional was attached to several implants and retrofitted into place following gingival sculpting to create a tooth emergence effect. To date, this patient has been followed for 2.5 years with no implant losses or bone level changes. In addition, the gingival profile appeared to be stable.
