Background: As the knowledge of the important of treatment the impacted canine since in many studies was considered as the key for ideal occlusion and to avoid the deleterious effect of lost, every effort must be done in order to retract and bring the impacted canine in to it is normal position. lower cuspid usually of a single rooted, but some time in about 15% of cases may have two canals in addition to that in a very rare cases approximately 1.7% associated with two roots. Our case showed these anomalies in addition to that the canine was horizontally impacted in the lower arch which is consider as challenge for many orthodontic since the angular of impaction was more than 25%. therefore, our case is a rare. Materials and Method: The treatment focus on the orthodontically extrusion and up righting of the impacted canine by using fix orthodontic appliance with the aid of traditional anchorage device (TDA). Result: this rare case was successfully managed with fix orthodontic treatment. Conclusion: Orthodontic extrusion of horizontally impacted incomplete transposition mandibular canine should be considered for similar cases.
