It was shown that the root elongation was inhibited and the malonaldehyde content in root apices and the antioxidase activities of root apices were increased under Al stress (30 μmol/L), while the effects of Al were significantly alleviated by the addition of Si (1.4 mmol/L). Moreover, both Si added before Al treatment and Si added simultaneously with Al treatment could alleviate these effects. On the other hand, the cultivar of Seca was shown to be more sensitive to Al than other cultivars in the absent of Si, while Al-resistance distinction among the cultivars of stylosanthes turned to be non-significant in the present of Si in the pre-cultured solution or both pre-cultured and Al-treatment solutions.

The study sample was composed of 40 female patients with maxillary excess or bimaxillary protrusion. The mean age of patient was 25.9. All patients had undergone the modified Wunderer technique for anterior subapical osteotomy. The postoperative follow-ups were all over 6 months. We studied the relationship between movement of anterior maxillary segment and soft tissue changes over nose and lip areas by the statistics in the hard tissue displacement and soft tissue changes 3 and 6 months postoperatively.

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。
