The purpose of this study was to assess the clinical efficacy of guided tissue regeneration (GTR) surgery using polylactic acid membrane. Twelve healthy patients with Class II furcation involvements or vertical defects, participated in this study. Probing pocket depth (PD) and clinical attachment level (CAL) measurements and dental radiographs were taken immediately before surgery and at 6 months after surgery. Mean PD was reduced from 6.5±2.3mm to 2.8±0.6mm, with a mean reduction of 3.8±1.9mm. Mean CAL was reduced from 7.5±2.1mm to 4.5±1.3mm, with a mean attachment gain of 3.1±1.8mm. Radiographic improvement in the defect area was observed in six out of 12 patients. No side effects were observed during the 6 months. This study suggests that GTR surgery using polylactic acid membrane might be useful for periodontal tissue regeneration therapy.
