This article describes an 11-year-old female patient who presented for orthodontic consultation because both permanent maxillary central incisors did not erupt after shedding of the predecessing deciduous teeth. The radiographic evaluation revealed four supernumerary teeth. Initially, these supernumeraries were surgically removed. After orthodontic space opening with fixed appliances and an open coil spring the impacted incisors were exposed, bonded with attachments, and actively elongated with elastic threads. At the end of treatment all teeth were optimally aligned and the gingival tissue appeared normal. Schlagwörter: Supernumerary teeth, impacted teeth, surgical exposure
