    THE DEVICE WAS RETURNED, THE INVESTIGATION HAS BEEN COMPLETED AND THE RESULTS ARE AS FOLLOWS: DHR RESULTS THE DHR WAS REVIEWED FOR LOT#6113530 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 THERE WAS NO STOCK PRODUCT FROM LOT#6113530 AVAILABLE FOR REVIEW. INVESTIGATION METHODS/RESULTS THE DEVICE WAS RETURNED BUT NOT IN ORIGINAL PACKAGE. THE IMPLANT WAS VERIFIED TO BE A HAHN TAPERED IMPLANT Ø4.3 X 8.0 MM (70-1154-IMP0009) USING RADIOGRAPHIC TEMPLATE (PK-209-062515). THERE WAS NO DEFECT OR NON-CONFORMITY OBSERVED, THE IMPLANT WAS STUCK IN CARRIER AND THE THREADS WERE INTACT. THE COMPLAINT IS VERIFIED BASED ON THE RETURNED PART(S) 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. IFU 570 REV 3.0 (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. PRIOR TO CLINICAL INTERVENTION, PROSPECTIVE PATIENTS MUST BE THOROUGHLY EVALUATED FOR ALL KNOWN RISK FACTORS AND CONDITIONS RELATED TO ORAL SURGICAL PROCEDURES AND SUBSEQUENT HEALING. 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 3.0 (HAHN TAPERED IMPLANT SYSTEM) CONTAINS THE FOLLOWING STATEMENT IN PRECAUTION SECTION SURGICAL PROCEDURES: "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. FOR BEST RESULTS, PLEASE OBSERVE THE FOLLOWING PRECAUTIONS: ALL DRILLING PROCEDURES SHOULD BE PERFORMED AT 2000 RPM OR LESS UNDER CONTINUAL, COPIOUS IRRIGATION. ALL SURGICAL INSTRUMENTS USED MUST BE IN GOOD CONDITION AND SHOULD BE USED CAREFULLY TO AVOID DAMAGE TO IMPLANTS OR OTHER COMPONENTS. IMPLANTS SHOULD BE PLACED WITH SUFFICIENT STABILITY; HOWEVER, EXCESSIVE INSERTION TORQUE MAY RESULT IN IMPLANT FRACTURE, OR FRACTURE OR NECROSIS OF THE IMPLANT SITE. THE PROPER SURGICAL PROTOCOL SHOULD BE STRICTLY ADHERED TO." IFU 570 REV 3.0 (HAHN TAPERED IMPLANT SYSTEM) CONTAINS THE FOLLOWING STATEMENT IN WARNING SECTION: "ABSOLUTE SUCCESS CANNOT BE GUARANTEED. FACTORS SUCH AS INFECTION, DISEASE AND INADEQUATE BONE QUALITY AND/OR QUANTITY CAN RESULT IN OSSEOINTEGRATION FAILURES FOLLOWING SURGERY OR INITIAL OSSEOINTEGRATION." IFU 570 REV 3.0 (HAHN TAPERED IMPLANT SYSTEM) CONTAINS THE FOLLOWING STATEMENT IN WARNING SECTION: "THE IMPLANT SITE SHOULD BE INSPECTED FOR ADEQUATE BONE BY RADIOGRAPHS, PALPATIONS AND VISUAL EXAMINATION. DETERMINE THE LOCATION OF NERVES AND OTHER VITAL STRUCTURES AND THEIR PROXIMITY TO THE IMPLANT SITE BEFORE ANY DRILLING TO AVOID POTENTIAL INJURY, SUCH AS PERMANENT NUMBNESS TO THE LOWER LIP AND CHIN."
