Since it includes root torque changes that might cause gingival recession, those situations often require periodontal, orthodontic and conservative treatment. Aim of this study was to assess the effectiveness of fixed orthodontic treatment with completely customized lingual appliances (CCLA) and continuous archwires for a clinically significant reduction in the dimensions of labial gingival recessions in the anterior mandible, caused by the wire syndrome (WS), in a group of consecutive patients treated with the same approach.
