ORAL & Implantology Anno I N. 3-4/2008 137 The gingival recession is clinically defined as the apical movement of the gingival margin to the cementoenamel junction (CEJ) (1). Histologically it is characterised by the loss of connective fibres of the periodontal tissue and alveolar bone (2). This clinical condition is frequently noticed in the population and particularly among patients with high oral hygiene standards. In fact, in addition to the inflammation caused by the bacterial plaque, the traumatic brush is considered one of the major causes of gingival recession. Gingival recession increases with age; the incidence varies from 8% among children to 100% in the adult population with more than 50 years of age (3). In addition to a wrong brushing technique and the gingival inflammation, the dental malpositioning can also cause recession. In fact the predisposition to the recession is linked to the position of the teeth in the dental arch, the dental-root angulation and the mesiodistal curvature of the dental surface. Teeth rotated, inclined or moved in the buccal direction show an osseous lamina thinned THE SURGICAL TREATMENT OF THE MULTIPLE GINGIVAL RECESSIONS
