Results: Before the fixed bridge was applied, under vertical load, the high-stress region was near around the apical of periodontal ligament with mainly compressive stresses. Under oblique load, the high-stress region was near around the cervical of periodontal ligament with both tensile and compressive stresses. After the fixed prosthodontics, stress and strain distributions were similar with that when the fixed bridge was not applied. But the maximum stress, strain and displacement increased apparently. The stresses in exterior surface of periodontal ligament were larger than that of interior surface; this character of periodontal ligament under vertical load was more obvious than that under oblique load.
