    Additional Manufacturer Narrative · 0

    THE DEVICE INVESTIGATION HAS BEEN COMPLETED AND THE RESULTS ARE AS FOLLOWS: DHR RESULTS THE DHR WAS REVIEWED FOR LOT# 6092536 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 THE PACKAGED STOCK PRODUCT IS NOT APPLICABLE FOR REVIEW SINCE NO DEFECT WAS OBSERVED FROM THE RETURNED PRODUCT. INVESTIGATION METHODS/RESULTS THE DEVICE WAS RETURNED WITH COVER SCREW STILL ENGAGED. THE IMPLANT WAS VERIFIED TO BE A HAHN TAPERED IMPLANT Ø4.3 X 11.5 MM (70-1154-IMP0011) USING RADIOGRAPHIC TEMPLATE (PK-209-062515). THERE WAS NO DEFECT OR NON-CONFORMITY OBSERVED AND THE THREADS WERE INTACT. BONE DEBRIS WAS OBSERVED IN THE THREADING OF THE IMPLANT. ROOT CAUSE "FAILURE TO OSSEOINTEGRATE" IS A COMMON COMPLAINT IN REGARDS 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 FAILURE TO OSSEOINTEGRATE IS INCONCLUSIVE AND SPECIFIC TO EACH CASE, PROBABLE CAUSES COULD BE THE LOSS OF PRIMARY STABILITY AT THE OSTEOTOMY SITE 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 HAD A HISTORY OF SMOKING. SMOKING IS KNOWN TO INHIBIT LOCAL WOUND HEALING AND MAY AFFECT SURVIVAL OF IMPLANTS. SMOKING HAS A STRONG INFLUENCE ON THE COMPLICATION RATES OF IMPLANTS. IT CAUSES SIGNIFICANTLY MORE MARGINAL BONE LOSS AFTER IMPLANT PLACEMENT, INCREASED THE INCIDENCE OF PERI-IMPLANTITIS (DEEP MUCOSAL POCKETS AROUND DENTAL IMPLANTS, INFLAMMATION OF THE PERI-IMPLANT MUCOSA, AND INCREASED RESORPTION OF PERI-IMPLANT BONE), AND AFFECTS THE SUCCESS RATES OF BONE GRAFTS. IFU 3027904 REV 2.0 (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. ALL DRILLING PROCEDURES SHOULD BE PERFORMED AT 2000 RPM OR LESS UNDER CONTINUAL AND 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 3027904 REV 2.0 (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 3027904 REV 2.0 (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.
