Long-term Clinical Evaluation of Coronally Advanced Flap with Chorion Membrane for the Treatment of Multiple Adjacent Gingival Recession Defects

Abstract

Multiple adjacent recessions are challenging defects since they present a number of critical anatomic features as large surgical field, frequently shallow vestibules and prominent roots as well as a variation in the size of defects and residual keratinized tissue. Different surgical techniques have been proposed for the treatment of multiple adjacent recessions, mainly derived from the coronally advanced flap with or without connective tissue graft or from tunnel approaches. Harvesting of connective tissue graft is time consuming, it is limited in quantity and exposes patient to another surgical wound. The overall objective of this study is to evaluate the effectiveness of Coronally advanced flap with Chorion membrane for the treatment of multiple adjacent gingival recession defects.
