Evaluation of Relative Efficacy of β-Tricalcium Phosphate with and without Type I Resorbable Collagen Membrane in Periodontal Infrabony Defects: A Clinical and Radiographic Study

Abstract

ABSTRACT Background and objectives To compare clinically and radiographically, the regenerative potential of a β-tricalcium phosphate bone graft, Cerasorb® with and without a bioresorbable type I collagen membrane, BioMend ExtendTM, in treating periodontal infrabony osseous defects. Materials and methods A total of 20 sites from 10 patients showing bilateral infrabony defects were selected and selected sites were randomly divided into experimental site A (Cerasorb®) and experimental site B (Cerasorb® and BioMend ExtendTM) by using split mouth design. The clinical parameters like plaque index, gingival index, probing pocket depth, clinical attachment level and gingival recession were recorded at baseline, 6 weeks, 3, 6 and 9 months. Radiographic evaluation (Linear CADIA) at 6 and 9 months; and intrasurgical measurements at baseline and 9 months were carried out to evaluate the defect fill, change in alveolar crest height and defect resolution. Results Significant reduction in all clinical parameters was observed in both the groups. On comparison no statistical significance was observed between the two groups. Radiographically, in site A there was significant defect fill of 78.4 and 97.2% at 6 and 9 months respectively. Whereas in site B reduction was 78.4 and 97.2% at 6 and 9 months respectively. After surgical re-entry, there was significant defect fill of 89.2 and 74% in both groups. Interpretation and conclusion Individually both the graft and membrane have shown promising results in the management of periodontal intrabony defects. But the added benefit by combining Cerasorb® with BioMend ExtendTM was not observed statistically in both clinical radiographic findings.
