Additional retention |

The labial bow is bent as usual. Then some zigzag inflections must be bent into the incisal part of the wire as retention means for the acrylic. |

In order to scatter the acrylic better, it is useful to frame the labial bow with wax. This wax frame should be shaped in a dimension that later corresponds to the thickness of the acrylic shield. |

On this occasion attention, should be paid on the counter bite. In order to avoid occlusal interferences, occasionally, the labial bow has to be adapted deeper. |
