There is growing evidence that human periodontal ligament fibroblasts are involved in this process.

Stress distribution of the natural periodontal membrane, bionic periodontal membrane and the bone interface of the three models are calculated out by SuperSAP93, when the same load exerted to the three models. Results The stress change of the inside and outside surface of the natural periodontal membrane and bionic periodontal membrane is in the same tendency.

应用螺旋CT对上颌中切牙标本进行扫描，分别建立仿生种植牙、天然牙和骨性结合种植体模型，对3个模型施加同样的载荷，应用Super SAP93软件，计算出天然牙周膜和仿生牙周膜以及3种模型骨界面上的应力分布。

The ultimate aim of periodontal treatment is periodontal regeneration or forming new attachment apparatus which is one of the hotspot of periodontology. Tissue engineering has been introduced into the field of periodontology, which contribute a new vista to periodontal regeneration. One of the important parts of tissue engineering is finding proper seeded cells.

牙周治疗的最终目标是牙周组织的完全再生和形成牙周新附着，因牙周病而丧失的牙周组织，其修复与重建的难度很大，传统的牙周治疗和引导性组织再生技术虽取得一定的临床效果，但总的看来，尚不能达到牙周组织完全再生的目的。

During the development of dental germ, enamel matrix proteins secreted by epithelial root sheath could induce dental follicle cells to differentiate towards cementoblast and form acellular cementum finally on the surface of tooth root. Many researches of domestic and oversea scholars suggest that enamel matrix proteins could effectively induce periodontal regeneration, and the structure and function of this regenerated tissue are similar to healthy periodontal tissue. Moreover, the regeneration process is nearly the same to that of embryonic development of periodontal tissue.

自发现釉基质蛋白可诱使牙囊细胞向成牙骨质细胞方向分化并在根表面形成无细胞性牙骨质以来，国内外学者做了大量研究，结果表明釉基质蛋白能有效诱导牙周组织的再生，且这种再生组织的结构和功能更接近于健康的牙周组织，并且再生过程也与牙周组织的胚胎发育过程类似。

The treatment to periodontal disease is mainly combined therapy,which control inflammation by periodontal medicine and operation;adjust interlocking,eliminate dental wound,relieve the burden of peridental supporting tissue by recovery treatment;fix the loose teeth,disperse the bite force,control the patho-loose and displacement,elevate the masticatory efficiency,make the troubled teeth to rest,is benefit to the control to periodontal inflammation and the healing of destructed periodontium.

牙周病治疗主要是综合治疗，通过牙周药物治疗、手术治疗来控制炎症；通过修复治疗调整咬合，消除牙创伤，减轻牙周支持组织的负担；固定松牙，分散力，控制病理性松动和移位，提高咀嚼效能，使患牙得到生理性休息，利于牙周炎症的控制和已破坏的牙周组织的愈合。

It has been showed that human periodontal ligament cell is a kind of polyclonal cells and play a great part in the course of periodontium reconstruction.

人牙周膜细胞(human periodontal ligament cell，hPDLC)作为牙周组织中的主要功能细胞，具有多向分化潜能，在创伤修复和组织再生中发挥着重要作用。

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。
