Guided Tissue Regeneration Based Treatment of Root Coverage using Placental Membrane Allograft: A Case Report.

ABSTRACT

Gingival recession is defi ned as the apical migration of gingival margin to the cementoenamel junction. It results in root exposure which leads to clinical problems such as root surface hypersensitivity, root caries, cervical root abrasions, diffi cult plaque control, and diminished aesthetic/cosmetic appeal. Guided tissue regeneration based root coverage has emerged as a promising treatment modality. A variety of non-resorbable and bioresorbable membranes have been successfully used. Among resorbable membranes, collagen has been extensively studied. Recently, amnion membrane, the third generation membrane which is a placental derived tissue has been introduced. On the basis of the fi ndings of the present case report, it can be concluded that recently introduced amnion membrane (third generation membrane) are equally effi cacious in the treatment of gingival recession and use of this resorbable membranes with coronally advanced fl ap is a versatile treatment modality for root coverage of isolated buccal gingival recessions. Th e more gingival tissue thickness (gingival biotype) enhancement was observed with this membrane. Amnion membrane has certain additive advantages over the collagen membrane such as better handling properties and a thin diameter enabling it to mold according to the defect anatomy and root surfaces easily.
