The orthodontic wire extends from the polymethylmethacrylate to engage the gingival aspect of the composite resin or orthodontic bracket serving to provide the prosthesis retentive undercut.

This blood clot is replaced with granulation tissue which consists of proliferating fibroblasts and endothelial cells derived from remnants of the periodontal membrane, surrounding alveolar bone and gingival mucosa.
