Abstract
Patients who have impacted tooth are found commonly in orthodontic treatment. Although it is difficult to find the cause of impacted teeth, the most common, causes are prolonged retention of the deciduous teeth, trauma, aberrant sequence of eruption, lack of space and deficiency of Vitamin D. Impacted teeth may lead to esthetic and functional problems and root resorption of adjacent teeth, so we should treat it as soon as possible. Commonly used treatment method is the following: After surgically uncovering of the impacted teeth, a bond of orthodontic appliance is established, and orthodontic traction is started with a removable or fixed appliance. We used the modified lingual arch with a soldered auxiliary appliance in lingual arch for traction of lower impacted teeth. The modified lingual arch could control the magnitude and direction of the applied force with one-arch treatment, and also could give continuous force to impacted tooth without patient patient cooperation. We achieved good results with the modified lingual arch.
