Risk during orthodontic treatment of the impacted teeth / 中华口腔医学杂志

ABSTRACT

The treatment of the impacted teeth is often challenging. During orthodontic treatment of the impacted teeth, unexpected tooth movement may occur for a variety of reasons including inadequate anchorage, inappropriate force vectors, ankylosis of the impacted tooth, traumatic external root resorption in adjacent teeth, and/or bony fenestration. Although cone-beam CT (CBCT) can clearly identify the location of impacted teeth, clinicians should avoid other difficulties before and during the traction of impacted teeth. This article discussed the risk factors during treatment of impacted teeth and presented some reasons of unsuccessful cases.
