Efficacy of Palatal Connective Tissue Graft as a Membrane in the Treatment of Intrabony Defects

Background and aims. The aim of this study was to compare clinical effects of two different membranes (palatal connec-tive tissue and collagen) in combination with Bio-Oss in the treatment of intrabony defects. Materials and methods. Fifteen patients who had at least a pair of intrabony defects with an attachment loss of g5mm and an initial osseous defect depth of g3 mm participated in this study. Probing pocket depth, clinical attachment level, posi-tion of gingival margin, bony defect depth and position of alveolar crest were measured before surgery and in re-entry proce-dure 9 months after treatment. Results. The results of this study showed that both techniques were effective in the treatment of intra-bony defects and both treatment modalities resulted in significant differences in all the parameters before and after surgery (Pl0.05). Conclusion. It was shown that, after treatment, considering all the variables in each group, there were significant improve-ments, but there were not any statistical differences in any of the variables between the two groups.
