THE DEVICE WAS RETURNED. THE INVESTIGATION HAS BEEN COMPLETED, AND THE RESULTS ARE AS FOLLOWS: DHR RESULTS: THE DHR WAS REVIEWED FOR LOT#6122036 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#6122036 AVAILABLE FOR REVIEW. INVESTIGATION METHODS/RESULTS: THE DEVICE WAS RETURNED BUT NOT IN ORIGINAL PACKAGE. THE IMPLANT WAS VERIFIED TO BE A HAHN TAPERED IMPLANTØ4.3 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. MATTER WAS OBSERVED IN THE THREADING OF THE IMPLANT. (SEE ATTACHED IMAGES).

ROOT CAUSE DESCRIPTION: "FAILURE TO OSSEOINTEGRATE" 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 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. PER THE REPORTED INFORMATION, THE PATIENT HAS A HISTORY OF DIABETES AND PERIODONTITIS.
