Hii Friends!!
This is a video about fabrication of helical canine retractor. This is a Step By Step demonstration. This canine retractor is used in canine retraction distally and is activated by either opening the coil by 1mm or by cutting the end of active arm 1mm and reshaping it to engage the medial surface of the canine.
