    THE INVESTIGATION HAS BEEN COMPLETED AND THE RESULTS ARE AS FOLLOWS: DHR RESULTS: THE DHR WAS REVIEWED FOR HAHN TAPERED IMPLANT LOT# 6082608 AND THERE WAS NO EVIDENCE DISCOVERED TO INDICATE THAT A PRODUCT DEFECT OR NON-CONFORMITY CONTRIBUTED TO THE ISSUE. THE PART MET ALL THE CRITERIA CALLED FOR IN THE PRODUCTION ROUTER. STOCK PRODUCT REVIEWED RESULTS: A REVIEW OF STOCK PRODUCT WAS PERFORMED FOR HAHN TAPERED IMPLANT LOT# 6082608 AND FOUND NO ADDITIONAL PRODUCT IN STOCK. INVESTIGATION METHODS/RESULTS: THE DEVICE WAS RETURNED BUT NOT IN THE ORIGINAL PACKAGE. AN ABUTMENT WAS ATTACHED TO THE IMPLANT. THE IMPLANT WAS VERIFIED TO BE A HAHN TAPERED IMPLANT Ø3.5 X 8 MM (70-1154-IMP0004) USING THE RADIOGRAPHIC TEMPLATE (PK-209-062515). THERE WAS NO DEFECT OR NON-CONFORMITY OBSERVED AND THE THREADS WERE INTACT. MATTER WAS OBSERVED IN THE TREADING OF THE IMPLANT. THE COMPLAINT IS VERIFIED BASED ON THE RETURNED PART BUT CANNOT CONFIRM THE FAILURE MODE. THERE WAS NO EVIDENCE FOUND THAT INDICATED THAT THE REPORTED ISSUE WAS CAUSED BY THE DEVICE ITSELF. ROOT CAUSE: "LOSS OF OSSEOINTEGRATION" IS A COMMON COMPLAINT IN REGARD TO IMPLANT FAILURE. THIS OCCURS WHEN THE PATIENT'S BONE DOES NOT INTEGRATE WITH THE IMPLANT SURFACE. THE POSSIBLE RESPONSES TO THIS COMPLAINT COULD BE ATTRIBUTED TO VARIOUS CAUSES. ALTHOUGH THE ROOT CAUSE FOR LOSS OF OSSEOINTEGRATION IS INCONCLUSIVE AND SPECIFIC TO EACH CASE, PROBABLE CAUSES COULD BE DUE TO INSUFFICIENT BONE OR POOR BONE QUALITY; EITHER THE BONE WAS TOO SOFT, OR THE OPERATOR ERRED IN CREATING AN OSTEOTOMY BIGGER THAN THE SIZE OF THE IMPLANT DIAMETER. PREMATURE LOADING, PATIENT'S HEALTH, PERI-IMPLANTITIS, SMOKING, AND LACK OF ORAL HYGIENE MAY ALSO BE CONTRIBUTING FACTORS. PER THE REPORTED INFORMATION, THE PATIENT HAS TYPE III BONE QUALITY. IFU-570 REV 2 (HAHN TAPERED IMPLANT SYSTEM) CONTAINS THE FOLLOWING STATEMENT IN THE CONTRAINDICATIONS SECTION: "HAHN TAPERED IMPLANTS SHOULD NOT BE PLACED IN PATIENTS DISCOVERED TO BE MEDICALLY UNFIT FOR THE INTENDED TREATMENT.

CONTRAINDICATIONS INCLUDE BUT ARE NOT LIMITED TO: VASCULAR CONDITIONS, UNCONTROLLED DIABETES, CLOTTING DISORDERS, ANTICOAGULANT THERAPY, METABOLIC BONE DISEASE, CHEMOTHERAPY OR RADIATION THERAPY, CHRONIC PERIODONTAL INFLAMMATION, INSUFFICIENT SOFT TISSUE COVERAGE, METABOLIC OR SYSTEMIC DISORDERS ASSOCIATED WITH WOUND AND/OR BONE HEALING, USE OF PHARMACEUTICALS THAT INHIBIT OR ALTER NATURAL BONE REMODELING, ANY DISORDERS WHICH INHIBIT A PATIENT'S ABILITY TO MAINTAIN ADEQUATE DAILY ORAL HYGIENE, UNCONTROLLED PARAFUNCTIONAL HABITS, INSUFFICIENT HEIGHT AND/OR WIDTH OF BONE, AND INSUFFICIENT INTERARCH SPACE." IFU-570 REV 2 (HAHN TAPERED IMPLANT SYSTEM) CONTAINS THE FOLLOWING STATEMENT IN THE SURGICAL PROCEDURES UNDER THE PRECAUTION SECTION: "MINIMIZING TISSUE DAMAGE IS CRUCIAL TO SUCCESSFUL IMPLANT OSSEOINTEGRATION. IN PARTICULAR, CARE SHOULD BE TAKEN TO ELIMINATE SOURCES OF INFECTION, CONTAMINANTS, SURGICAL AND THERMAL TRAUMA. RISK OF OSSEOINTEGRATION FAILURE INCREASES AS TISSUE TRAUMA INCREASES.
