All defects were reentered after 9 months. Class III furcations closed 66% of the time when treated by the first method, while the closure rate was only 33% when treated by the second method (no polyglactin mesh). Defects with a vertical opening less than or equal to 4 mm closed 74% of the time, while those with vertical openings > 4 mm closed only 11% of the time.
