I have been doing my denture id's almost the same way for quite a long time and have never really been satisfied with the staining. I use cold cure to place the id in and the id itself is shrink material typed with a typewriter and shrank down then I place a thin layer of super glue to create a layer over the ink to protect it from being damaged by monomer. I have tried triad gel and thats OK but it seems to collect tarter. lly I would like them to somehow be heat cured in the denture during the injecting or packing stage. I know someone has got to have a better way than cutting out a window and cold curing them into place for hell sake we are denture techs we can always think of something right. Any ideas or techniques would be appreciated.
