Viability of Amnion-Chorion membrane with the trophoblast layer in augmented posterior extraction sockets

Abstract

Augmentation of the extraction sockets with bone and a membrane prior to dental implants insertion has been an integral part of the dental practice due to the advantages of providing adequate hard and soft tissue support essential for the implant emergence profile. Several bone graft materials and membranes have been recommended for the socket preservation however most of the commercially available resorbable membranes dissolve prematurely when exposed resulting in loss of the graft material. With the introduction of the human placental membranes into the dental field expedited wound healing was demonstrated even when exposed due to the abundance of growth factors. In this study Amniotic membrane which processed in a way to preserve the trophoblast layer has been tested on top of augmented extraction sockets . Clinically this membrane was easier to handle due to the increased thickness as a result of combining amnion chorion and trophoblast layer , it has also shown expedited healing through tissue formation on top of the bone graft mass as soon as two weeks. The histological examination demonstrated a considerable layer of fully matured epithelized tissue covering the bone in a short period of time. The results confirmed the viability of the Amnion Chorion and trophoblast membrane in generating epithelized tissue is a short period of time when used in covering bone grafts in extraction sockets.
