Abstract :
Infra occlusion of teeth can be due to many factors like tissue resistance, unavailable space in arch. In orthodontic treatment such a tooth can be extruded by various mechanics. A tooth that is translated along its long axis in a coronal direction is called an extrusion. In literature many case reports are available for orthodontic extrusion of canine but less reports have been there about orthodontic traction for impacted and intruded premolar. So, this case report represents versatile extrusion spring for extrusion of infra-occlusion premolar without anchor loss of adjacent teeth.
