An anchor member for a tooth regulating band comprises an open-ended barrel-shaped member which, owing to its convexity, grips the tooth or teeth and does not ride away from the gums. It may be in the form of a band fitting around one or more teeth or may comprise two such members, around one or more teeth, which are joined by a regulating band also having a concave surface directed towards the teeth. |
