Introduction: Human placental membranes have been used in the field of medicine for skin grafts, treatment of burns, ulcerated skin conditions etc. with great success. The use of placental allografts in dentistry is a more recent development, with the first commercial product being made available in 2008. The unique inherent biologic properties enhance wound healing and may propagate regeneration. Case Series: Ten healthy adult patients presenting with twenty-one Millers Class I recession defects (isolated or adjacent multiple) were surgically treated with a modified coronally advanced flap and Chorion membrane for root coverage. Clinical parameters measured at baseline, 3 months and 6 months were probing depth (PD), clinical attachment level (CAL), recession height (RH), width of keratinized gingiva (WKG) and assessment of gingival biotype. Statistical analysis was carried out to compare the treatment outcomes at the follow-up intervals. The results showed statistically significant (p <0.001) improvements in all clinical parameters at 3 and 6 months follow up. The mean percentage root coverage at the end of 6 months was 89.92±15.59% and 14 of 21 treated recession defects showed a 100% root coverage. The gingival biotype also showed a thick biotype in 9 sites which had an initial thin biotype. Conclusion: Foetal membranes possess distinctive properties which can be harnessed to promote periodontal healing. The Chorion membrane covered by a modified coronally advanced flap, is a new approach that has shown promising results in terms of root coverage, increased width of keratinized tissue and thickness of the gingival biotype.
