Abstract

The authors installed implants combined with guided bony regeneration (GBR) using autogenous tooth bone graft material in the patients. In one patient, GBR and simultaneous implant placement were performed. In two patients, GBR was performed and the implants were placed after 6 months. All patients achieved favorable clinical outcomes. Excellent osteoconductive bony healing was observed in the 6 month histology examination after the bone graft.
