Impaction of permanent incisor occurs rare than the canine & third molar. But it's often observed in school age child. The causes of impaction are trauma, space deficiency, mesiodens, infections of root apex, etc. In spite of elimination of cause, normal eruption of impacted tooth is rare. Though eruption is normal, the position of tooth will be incorrect. Because the impacted tooth results in malocclusion, root resorption of adjacent tooth, pathologic cystic change, it should be confirmed the precise position by clinical and radiographic exam and found the correct location by appropriate treatment plan. In case of pathologic change of impacted tooth and injury to adjacent tooth, it will be extracted. But through orthodontic retraction, the function and esthetics of tooth can be restored. It is important that impacted tooth should be detected early and diagnosed correctly, and appropriate treatment plan should be made. Before impacted tooth is retracted, the considerations of space for alignment and anchorage should be preceded and through appropriate force and mechanics, the side effects, for example, a root resorption should be minimized. In this study, we guided impacted tooth to normal position by using a forced eruption.
