Abstract

Background:  Ectopic eruption of maxillary canine is a commonly encountered problem in Orthodontic practice.  Two methods have been developed for canine retraction sliding mechanics and loop mechanics.  In the case being presented a 20-year-old boy with an ectopically erupted left maxillary canine and retained deciduous canine and second molar on the same side with a 90-degree rotation of the upper left central incisor was aligned with a segmented t loop retraction spring which delivered a light continous force on the left canine and a couple force for the de-rotation of the central incisor in combination with a palatal nance button to reinforce the anchor unit and a bypass arch wire. The results were stable both functionally and esthetically and to ensure satisfactory post treatment alignment of the maxillary and mandibular anterior dentition, the continued use of fixed retainers was recommended indefinitely.

Keywords: Ectopic canine, segmented T loop retraction spring, Rotated central incisor, Bypass arch wire.
