Comparative Clinical Evaluation of Freeze-Dried Skin Allograft and Autogenous Subepithelial Connective Tissue Graft in the Management of Human Localized Gingival Recession.

Abstract

The present study was conducted in order to evaluate and compare the use of the acellular dermal matrix "AlloDerm" in the management of class I and II localized marginal tissue recession. Twenty localized marginal tissue recession sites class I and II Miller's classification were treated in this study. Ten cases were treated with subepithelial connective tissue graft Langer and Langer's technique, while the other ten cases were treated with the "AlloDerm". All patients were subjected to through clinical examination in selected sites; including : visible recession, probing depth, loss of attachment, width of Keratinized tissue and papillary bleeding index. All these clinical parameters were taken prior to surgery, and at 1, 3, 6, and 9 months post surgically. Results: The results of the present study showed that the subepithelial connective tissue graft healed uneventfully with excellent color matching. Also it shows that the acellular dermal matrix allograft material was well tolerated and highly integrated with the oral soft tissues. Moreover, it showed excellent color matching with no line of demarcation from the surrounding gingiva. When both techniques were compared, no statistical significant difference was found between both groups regarding all measurements including; visible recession, width of keratinized
