The use of a collagenated porcine cortical lamina in the reconstruction of alveolar ridge defects : a clinical and histological study

The use of resorbable and non-resorbable membranes has been proposed to increase the hard tissue volume in deficient sites. For vertical GBR is necessary to use non-resorbable devices to maintain the volume. Collagenated porcine cortical barrier seems to have different clinical advantages, including: stability of the membrane; the plastic consistency; the absence of a second re-entry surgery for its removal; the quality of integration; decreasing the risk of infections in case of exposure. The purpose of this study was therefore to clinically and histologically evaluate the use of collagenated porcine bone lamina in case of horizontal and vertical bone augmentation procedures in conjunction with particulate porcine xenograft.
