7. Hints
Hints for reducing the remaining monomer content
To reduce the remaining monomer content the completed
appliance should be immersed int water for three days, if
possible, before the patient uses it. The watering has the
effect that the remaining monomer is reduced to values
similar to those of heat-curing synthetic resins. Should this
not be possible, it is recommended that the patient also pla-
ces the appliance into water, during the tim it is not worn.
