ABSTRACT
<p><b>OBJECTIVE</b>To investigate the stress distribution in the mandibular fixed partial denture (FPD) by changing the length of pontics.</p><p><b>METHODS</b>Based on a 3-DFE model of the mandibular FPD, we analyzed the stress distribution in the mandibular FPDs by loading the same level force at pontics with different lengths that were 2 to 4 times of normal length.</p><p><b>RESULTS</b>The distribution trends of the stresses in the mandibular FPDs with differently elongated pontics were similar, but the highest von Mises stress in the bridge was enlarged.</p><p><b>CONCLUSION</b>Damages may develop in the mandibular FDP, when the length of the pontic is longer than 3 times of normal length.</p>
