Poor demonstration. How can the tooth be moved Distally ? No space for it to move to. The wire should cross the interstitial space at occlusal surface hight not at tissue hight ( see any text book) No guard wire for the active arm to stop it irritating the tissue. Seems to have been demonstrated by a technician who has no academic knowledge of the principles of construction. I have banned my students from this site as it full of misinformation
