This paper describes a surgical technique that permits the achievement of bilateral simultaneous augmentation of the maxillary sinus floor with the use of autologous bone harvested from the mandibular symphysis alone. Out of a group of 26 partially edentulous patients consecutively treated for sinus augmentation in an 18‐month period, eight needed a bilateral procedure and were treated with the same surgical protocol. None of the patients had residual molar teeth, crestal bone height was reduced to 4 mm or less. Bone was harvested from the chin in blocks with a trephine bur, 11 or 9 mm in diameter, it was then particulated with a bone mill. Sinus augmentation and implant placement were done simultaneously in both sides of the maxilla. Implant‐supported fixed partial dentures were inserted 6 months after the procedure. 44 ITI solid screw implants were placed in the grafted sinuses with a mean of 2.75 implants on each side. Mean follow‐up was 19 months. In all patients needing a bilateral sinus lift, the procedure could be successfully completed. All implants were stable at abutment connection. All implants are stable at the latest follow‐up, and all prosthesis are still working. In all implants, a clear bone‐to‐implant contact was visible. No peri‐implant radiolucency has been noticed so far. It is concluded that bilateral augmentation of maxillary sinus floor with particulated mandible associated with simultaneous ITI implant insertion is feasible. It is a safe and effective procedure that can be accomplished in an out‐patient environment with only minor discomfort for the patient.
