Fig. 1: Initial OPG (7 years after implantation).
Female patient, 75 years old, generally healthy, non smoker.
Seven years before, the patient had received an implant reconstruction in the mandible with ten conventional 2-stage implants (Fig.1).
Four implants in left mandibular area were lost during first year after surgery. Presented picture is the result seven years after implantation. French surgeons recommended bone transplantation for augmentation of the mandible and delayed implantation, but the patient did not want any additional procedures. Our proposal was to remove all 2-stage implants, bone curettage with simultaneous insertion of six KOS® implants and immediate loading.
