Fall7

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 a result after 7 years after implantation. French surgeons recommended bone transplantation for augmentation of the mandible and delayed implantation but patient didn’t want any additional procedures. Our proposal was removal of all 2-stage implants, bone curettage with simultaneous insertion of 6 KOS® implants and immediate loading.
