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.

结果：固定桥修复前，垂直载荷下，基牙牙周膜的应力以压应力为主，应力集中在根尖；斜向载荷下，基牙牙周膜的应力主要是拉应力和压应力，应力集中在唇、舌颈缘；固定桥修复后，基牙牙周膜的应力和应变分布规律与修复前相似，但最大应力、应变值都明显增大；牙周膜内表面的应力大于牙周膜外表面；垂直载荷时，牙周膜内、外表面的应力差异更为显著。
