The value of resins for model dies is controversial. This objective study indicates that epoxy- and epimine resins may be successfully used as die materials, if certain measures are taken as a precaution. The resin should be centrifuged and a slight contraction of the material must be calculated into the chain of manufacture. The material should not be poured into hydrocolloid impressions, as the humidity of this impression material may interfere with the proper polymerization of the resin. A major inconvenience are the frequent formation of air bubbles on the angles of the preparation, and this in spite of the use of the vibrator.
