Volume 8: In the context of fixed dental prostheses, for esthetic and hygienic reasons it may be advisable to perform horizontal soft tissue augmentation using connective tissue taken from the lateral palate, or from the tuberosity region. From a clinical perspective, there are two proven techniques: the inlay technique can achieve horizontal augmentation of the alveolar crest and cause thickening of the papillae adjacent to the edentulous space. To cover the graft completely, an additional palatal island flap is recommended. Alternatively, pouch techniques have proven successful where pockets are prepared by undermining and connective tissue grafted into these pockets. A modification of the procedure allows the soft tissue to be concurrently contoured by the pontiffs of the provisional bridge. This volume presents both techniques.
