[Free mucosal transplantation in accidental periodontal lesions]

In order to eliminate mucogingival adhesions after lesions of the vestibulum caused by an accident, they must be freed and the scars must be excized. To create and restore a sufficiently broad gingiva propria and to deepen the vestibulum, the new wound area should be covered by a graft which at the same time counteracts resorption of the alveolar bone. A free graft from the palatal mucosa is suitable. It ideally replaces the alveolar mucosa, since it is the same type of mucosa as the attached gingiva, i.e. compact fibrous keratinized mucosa, and leads to bone apposition by activating the osteoblasts. Clinical experience and histological examinations show that this transplant permanently keeps its characteristics and undergoes secondary shrinking to a small extent only.
