The aim of this controlled, clinical study was to evaluate guided tissue regeneration using a bioabsorbable membrane in periodontal intraosscous defects. Forty patients, each contributing one defect ≥4 mm in depth participated. The control group (18 individuals) received conventional flap therapy. while the test group (22 individuals) was treated using the bioabsorbable membrane. Guid-orb. Clinical assessments were made by one examiner, blinded with respect to treatment group, at baseline. 6 and 12 months following surgery Baseline probing pocket depths of 7.7 ± 1.4 mm in the membrane group and 7.6± 1.9 mm in the control group were measured. Twelve month results showed a significant clinical attachment level gain in both control (11 ± 1.8 mm). and membrane group (1.3 ± 2.1 mm). Probing pocket depth reduction of 2.6± 1.9 mm and 2.7± 1.9 mm was observed in the respective groups. Bone sounding showed a non-significant gain of 0.4 ± 1.8 mm and 0.6 ± 1.4 mm at membrane and control sites. respectively Radiographic evaluation confirmed these results. There were no significant differences found between treatment groups for any of the tested variables. Smoking had a negative effect on healing in both groups. In conclusion, clinical and radiographic results indicate that guided tissue regeneration using a bioabsorbable membrane at intraosseous defects did not predictably achieve greater clinical attachment level gain nor bone gain when compared to conventional flap therapy.
