This retrospective case series presents results from eight patients treated with demineralized freeze-dried bone allograft particles and barrier membranes using either miniscrews or implants to support the membrane in seven patients. In all patients, the amount of vertical bone regeneration enabled placement of one or more implants in the graft sites, followed by loading with definitive prostheses at least 5.5 months after implant placement. Marginal bone heights around the implants have remained stable throughout 4 to 13 years of follow-up. (Int J Periodontics Restorative Dent 2010;30:227–235.)
