摘要：The removal of molar denture was made from PMMA polymer. The alternating load of dental during the
process of chewing food therefore it is failure by fatigue. In fatigue failure the crack was initiate then crack
propagate. In this paper, the effect of repeated load on life of removable molar denture was study, the
PMMA molar was manufacturing then testing to determine mechanical properties by compression fatigue
load tester. Also, the mechanical properties of the material were examined as a test of compression and
hardness. The force of load is find by special sensor. Finally, the repeated load on removable dental molar
can be reduce the life of the dental to less than half.
