In those Tori cases, extreme or not. I always have wire overlap. Even on a modle with no tori.

An Orthodontist and I were talking about this, wants me to try both ways. Either wire overlap or very short wires in the acrylic. He feels that if it the wire is in the acrylic is long but with not over lap it makes the acrylic break where there is no overlap. Mainly because the acrylic cant flex where there is a wire and can flex where there isn't, so they break every time at the junction of flexability and non-flexibility. Kinda like all the flexing force is concentrated at that one point.
He wants me to try making the "tags" (the embedded part of the wire) short so that the flexibility is distributed over the whole retainer. Kinda straight down with a little bend for retention.
Should make quick work of bending wires
