BMP-2/ACS/allograft for combined maxillary alveolar split/sinus floor grafting with and without simultaneous dental implant placement: report of 21 implants placed into 7 alveolar split sites followed for up to 3 years.

This report presents seven patients who were treated with combined alveolar split/sinus grafting technique and dental implants and followed for 1 to 3 years. The grafting material included bone morphogenetic protein-2 in an absorbable collagen sponge plus allograft. The procedure was successful in all patients, who received implants either simultaneously with grafting or 4 to 6 months after grafting.

Maxillary full-arch alveolar split osteotomy with island osteoperiosteal flaps and sinus grafting using bone morphogenetic protein-2 and retrofitting for immediate loading with a provisional: surgical and prosthetic procedures and case report.

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.
