A new device for traction of dilacerated maxillary central incisors.

for treating an impacted, dilacerated maxillary central incisor in the mixed dentition. A new fixed appliance promotes proper sagittal and vertical traction of the incisor into the dental arch, while maintaining the patient’s periodontal health and preserving root length. The appliance is an .040" stainless steel fixed lingual arch, soldered to the lingual surfaces of the maxillary first molar bands (Fig. 1). A vertical arm of the same wire type, ending in a helix, is soldered to the arch at the center of the incisor space. Four metal occlusal rests are soldered to the lingual arch: two on either side of the impacted incisor and two at the first deciduous molars. These rests are bonded to the teeth with light-cured composite.
