I can provide a little practical advice from my own experience with dental repair in remote
#1. The biggest thing I learned was you need to get the area dry, and keep it dry (for about 30 minutes), or your saliva will wash out the fix. Q-tips for getting the area dry, and big wads of cotton (cloth or balls) or paper towels to keep it dry, Do this way longer than you think. If you don't do this either the repair will not stick or it will wash out.
#2. I had one of those 'emergency dental kits' and found the cement to be hopeless. Easily washed out and weak once set up. I used up the whole kit and still did not have an acceptable fix. Probably a skilled dentist could make it work but I could not. Perhaps some practice before hand or more instructions might help.
I then called my dentist on the iridium phone
and he asked what else we had on board and the marinetex (relatively fast cure thickened epoxy) was his pick. And it worked perfectly. I made a crown replacement with it, which lasted 9 months (until the dentist drilled it out) and when it was drilled out he said it was a perfect job and not really any worse than what he was going to redo. After the epoxy
was 'semi cured', I could bite down on it and squash/shape it, so that it was a perfect 'bite pattern/height'.
Note: I was just following professional advice on this and don't have any knowledge on this myself . . . I strongly suspect you don't want to eat a bunch of the marinetex
. . . but the 'pro' thought it was the best choice from what I had available.
