CLINICO-RADIOGRAPHIC EVALUATION OF GUIDED TISSUE REGENERATION USING COLLAGEN MEMBRANE AND BIPHASIC CALCIUM PHOSPHATE IN TREATMENT OF INTRABONY PERIODONTAL DEFECTS

Abstract

Background: The ideal result of successful periodontal therapy is periodontal regeneration. Guided tissue regeneration is considered currently as gold standard for periodontal regeneration. Poor mechanical properties, biomaterials instability and lack of biocompatibility of regenerative membrane alone led to direct use of bioactive materials in defect area. So, this study was intended towards evaluation of effectiveness of resorbable membrane with bioactive molecule containing biphasic calcium phosphate determined by amount of bone fill both clinically and radiographically.

Methods: A total of 20 intrabony defects from sixteen patients were selected. The study designed was Quasi experiment, a quantitative non randomized experimental trial. The clinical parameters like Plaque index, Gingival index, Pocket probing depth, Amount of Gingival recession and relative attachment level were recorded at baseline and after 6 months by using acrylic surgical stent following periodontal access flap surgery along with use of collagen membrane and alloplast bone graft. Radiographic parameters were taken using Orthopantomograph for measuring the radiographic bone fill at baseline and after 6 months. Data were analyzed using paired t-test and Wilcoxon sign rank test.

Results: All the parameters post operatively were statistically significant. Clinically, gain in attachment was 2.1±1.25mm and pocket reduction was 3.35±1.39mm whereas linear radiographic bone fill was found to be 2.81±1.43mm. However, gingival recession was found to be increased post-operatively.

Conclusions: The current study showed combination of bone alloplast and regenerative membrane yields promising results in treatment of human intrabony periodontal defects.
