Abstract
Obturator is a prosthetic appliance that is used to restore irreparable maxillary defects. The frames
were supposed to form the infrastructure of the obturator that intends to close the maxillary arch defects. Five
main types of maxillary defects according to Aramany classification were selected for this study. 15 different
design frameworks were fabricated using Co-Cr dental alloy. The defects were simulated using premade
maxillary arch models that were reproduced in photo-elastic resin. The fabricated metal frames were seated on
the photo-elastic resin models and then were exposed to standardized stress at 3 different locations on the
frames using a global testing machine. A custom made plane polariscope was arranged to provide polarized
illumination for the light emission and analysis through the models. The photo-elastic resin models were
photographed during loading under the testing machine to display the supporting areas deformation
in frontal plane. The results showed that the proposed metallic designs variably distributed the stresses around
the abutments and the remaining hard tissues on the photo-elastic models.
