HOWEVER, THE NON-VISUAL DEVICE INVESTIGATION HAS BEEN COMPLETED. ROOT CAUSE THE ROOT CAUSE CANNOT BE EXPLICITLY DETERMINED. THE PROBABLE ROOT CAUSE FOR THIS FAILURE COULD BE DUE TO HOW THE PATIENT USED THE RESTORATION SUCH AS POTENTIALLY BITING DOWN A HARD OBJECT WHICH CAN CAUSE A RESTORATION TO FRACTURE. IT IS UNKNOWN THE PATIENT'S MEDICAL HISTORY, BUT BRUXISM CAN ALSO CAUSE THE RESTORATION FRACTURE OVER TIME DUE TO THE EXCESSIVE PRESSURE AND GRINDING ON THE RESTORATION WHICH CAN LEAD TO THE DECREASE IN STRENGTH OF THE RESTORATION. THE MANUFACTURER INTERNAL REFERENCE NUMBER IS: COMP-(B)(4).
