In certain cases the labial bow of the upper jaw can be extended to influence the lower jaw. Normally, the horizontal part runs along the lower teeth in centric occlusion. At canine level the wire is bent 90° forming the loops and then is anchored in the upper jaw. |

It is also possible to solder or laser a separately bent intermaxillary bow onto a standard labial bow on the upper jaw. It is important to remember that conventional or laser weldable wire has to be used for both bows. |

A variation of the intermaxillary bow is a labial bow with an additional helix in the loops in order to increase the elasticity of the bow. |
