Self curing resin cement

[JvandebergIII]

I have a bridge (lower) that goes over two canines (both non vital) and would like to know if it is safe for me to use a self curing resin cement to put the bridge back in myself …

A bridge that goes from lower right canine to lower left canine, and is replacing the 4 lower incisors? AND the canines are root-filled?!
That is not going to work, and you run the risk of snapping off the canines. It would be better to place single crowns on the canines, then either consider implants of denture to replace the incisors.
