    Description of Event or Problem · 1

    THIS REPORT IS BEING FILED AFTER SUBSEQUENT REVIEW OF THE FOLLOWING JOURNAL ARTICLE: A CASE REVIEW WAS PERFORMED OF 8 PATIENTS WHO HAD UNDERGONE RHBMP-2 BONE GRAFTING USING POROUS POLYETHYLENE AS THE CONTAINMENT DEVICE. EIGHT MAXILLARY AND TWO MANDIBULAR ALVEOLAR DEFECTS WERE GRAFTED USING RHBMP-2 AND TITANIUM-REINFORCED POROUS POLYETHYLENE AS A SOFT TISSUE BARRIER. ONE PATIENT RECEIVED AUTOLOGOUS RAMUS BONE IN ADDITION TO THE RHBMP-2. ALL PATIENTS WERE FOLLOWED UP BY CLINICAL EXAMINATION AND PERIODIC RADIOGRAPHIC STUDIES FOR 6 MONTHS TO 2 YEARS. IMPLANT-BORNE PROSTHESES WERE FABRICATED ON ALL SUCCESSFUL GRAFTS. A (B)(6) MAN. AT POSTOPERATIVE DAY 7, THE SYNPORE BARRIER WAS EXPOSED AND MOBILE. THE PALATAL POSITIONAL SCREW WAS LOOSE AND NO LONGER SECURING THE BARRIER ON THE PALATAL SURFACE. BECAUSE OF THE INSTABILITY, THE BARRIER AND GRAFT WERE REMOVED. THE AREA WAS SUBSEQUENTLY REGRAFTED WITH AUTOLOGOUS AND ALLOGENEIC BONE AND AN IMPLANT LATER PLACED. OF THE 10 GRAFTED ALVEOLAR DEFECTS, 2 (20 PERCENT) RESULTED IN EARLY EXPOSURE OF THE CONTAINMENT DEVICES, WERE REMOVED, AND RESULTED IN NO BONE FORMATION. ONE OF THE 10 DEFECTS (10 PERCENT ) BECAME EXPOSED 3 MONTHS POSTOPERATIVELY AND RESULTED IN ONLY MODERATE BONE FORMATION. IN THE 7 NONEXPOSED CASES ((70 PERCENT), BONE FORMATION WAS EXCELLENT, AND IMPLANTS WERE SUCCESSFULLY PLACED. THIS REPORT IS 2 OF 4 FOR (B)(4).
