Clinical and radiographic evaluation of regenerative potential of GTR membrane (Biomesh®) along with alloplastic bone graft (Biograft®) in the treatment of periodontal intrabony defects.

BACKGROUND AND OBJECTIVES: The primary goal of periodontal therapy is to restore the tooth supporting tissues lost due to periodontal disease. The aim of the present study was to compare the efficacy of combination of GTR membrane and alloplastc bone graft with open flap debridement (OFD) in treatment of periodontal intrabony defects.

METHODS: Twenty paired intrabony defects were surgically treated using split mouth design. The defects were randomly assigned to treatment with OFD, GTR membrane+bone graft (test) or OFD alone (control). The clinical efficacy of two treatment modalities was evaluated at 6 months postoperatively by clinical, radiographical parameters. The measurements included probing pocket depth (PD), clinical attachment level (CAL), gingival recession (GR), bone fill (BF), bone density (BD).

RESULTS: The mean reduction in PD at 0 to 6 months was 3.20±0.82 mm and CAL gain of 3.10±1.51 mm occurred in the GTR membrane+bone graft (test) group; corresponding values for OFD (control) were 2.10±0.63 mm and 1.90±0.57 mm. Similar pattern of improvement was observed when radiographically postoperative evaluation was made. All improvement in different parameters was statistically significant (p<0.01).

CONCLUSION: Treatment with a combination of collagen membrane and bone graft led to a significantly more favorable clinical outcome in intrabony defects as compared to open flap debridement alone.
