Introduction Primary closure of augmented extraction sockets is one of the most challenging procedures in oral surgery as it requires vertical releasing incisions and undermining of the buccal mucosa to establish primary closure. This commonly used technique has been successful in wound closure; however, it has the disadvantage of loss of the buccal keratinized tissue due to flap positioning towards the lingual flap edges. Case Presentation This case series demonstrates the effectiveness of the dehydrated human amnion/chorion membrane (dHACM) in increasing the attached keratinized tissue over augmented extraction socket wounds and thus expanding the tissue. Patients with posterior extraction sockets were treated using the same bone graft material. The distance between the buccal and lingual flaps was measured and recorded. The dHACM was tucked underneath the buccal and lingual flaps by approximately 2 to 3 mm, secured with sutures, and left to heal. Postoperative visits were scheduled at 2‐, 4‐, and 12‐week intervals for observation of the healing and treatment of any complications. Conclusions At 12 weeks postoperative, the amount of bucco‐lingual attached keratinized tissue was measured on the horizontal ceiling of the healed extraction socket and recorded. It showed gain in the keratinized tissue on top of the bone graft when the membrane was used. Although the membrane was exposed, no loss of the bone graft material was reported.
