Impaction of the lower second molar is not a common problem (0.03%), but it is very challenging for orthodontists. Unilateral mandibular second molar impaction is the most popular form of second molar impactions. The etiology of which is related to some disturbances in physiological mandibular growth and tooth development. Other factors have been cited for this problem is iatrogenic such as space gaining procedures in mixed dentition. Treatment options depend on degree of tooth inclination, the position of third molar and desired type of tooth movement. Advantages of impacted molar uprighting arc functional, periodontal and restorative. In this case report, treatment of partially impacted second molars in a 12 year — old girl with class I malocclusion is presented. Uprighting of both second molars was performed in two stages. It was concluded that using continuous stainless steel wire with T-loop and gable bend is an effective method for correction of second molar inclination with the least risk of molar extrusion.
