Black triangles after lower incisor extraction are one of the commonly occurring malocclusion which causes esthetic compromises. Relapse is unavoidable while treating such cases. This relapse can be controlled only when there is translatory root movement in the mesial direction. Very little literature is available for the correction of black triangles. In this article, a spring is fabricated by using 0.018 A J Wilcock stainless steel special plus wire containing three helices. This Trihelical spring is a simple, effective, esthetic, and biologically compatible device with excellent root control for the treatment of root divergence.
