In this article, collagen protein was extracted from bovine tendon by enzyme digestion and was spread to form membrane materials. Then the materials were crosslinked by formaldehyde to form guided tissue regeneration materials. The results from the test of physical and chemical properties of materials show that the mechanical properties and water absorption ability of materials exceed those of foreign products. Also the major structrual groups like carbonyl, carboxy, hydroxy and amino groups still exist. According...

In this article, collagen protein was extracted from bovine tendon by enzyme digestion and was spread to form membrane materials. Then the materials were crosslinked by formaldehyde to form guided tissue regeneration materials. The results from the test of physical and chemical properties of materials show that the mechanical properties and water absorption ability of materials exceed those of foreign products. Also the major structrual groups like carbonyl, carboxy, hydroxy and amino groups still exist. According to the observations of collagen enzyme in vitro and muscle implantation in vivo tests, the degradation times of the materials in vitro and in vivo are 240 hours and 60 days respectively and the degradation residue is hydroxyproline. The results of biological evaluations show good biocompatibility and no anaphylaxis,pyrogen and carcinogenicity. Therefore, it is concluded that as a kind of guided tissue regeneration material it is suitable for clinical use in guided tissue regeneration of oral diseases and also many other diseases.Correspondent: ZHANG Qiqing, Professor, Institute of Biomedical Engineering.Chinese Academy of Medical Sciences,P.O.Box 25(204), Tianjin 300192

用酶消化法从牛腱中提取出胶原蛋白,采用涂复法制成胶原膜材料,将该膜用0.25%的甲醛交联后得到用于牙周组织引导再生的材料.在对胶原材料进行物理、化学性能测试后表明:该材料的力学性能超过国外同类制品并具有较好的吸水性,而且胶原材料的羰基、羧基、羟基和胺基等主要结构基团依然存在经体外胶原酶和体内肌肉包埋降解吸收观察,材料在体外约240小时降解完全,降解产物为羟脯氨酸,体内吸收时间为60天左右.对该材料进行生物学评价后证明:该材料无三致反应和其它毒副作用,无热原和过敏反应及溶血现象等,生物相容性优良.因此,该材料可用于牙周组织引导再生术及更广泛的生物隔膜技术中.

Objective:The aim of this study was to evaluate the efficiency of domestic expanded polvtetrafluoroethylene (e PTFE) membrane on periodontal guided tissue regeneration (GTR). Methods:The periodontal defects of 10 dog teeth treated with e PTFE were investigated for three monthes, and compared with the contrals (7teeth). Results:The periodontal guided tissue regeneration in the treated group were significant higher than those in the control group ( P <0.05), but they did not recovered to the clinical...

Methods:The periodontal defects of 10 dog teeth treated with e PTFE were investigated for three monthes, and compared with the contrals (7teeth). Results:The periodontal guided tissue regeneration in the treated group were significant higher than those in the control group ( P <0.05), but they did not recovered to the clinical attachment level at the end of third month. Conclusion:Our study indicatis that e PTFE membranes seem to be possible to produce the GTR in the replacement of periodontal defects.

目的:本文对应用国产膨体e-pTFE膜引导牙周组织再生的动物实验的观察进行评价。方法:通过4只狗的10颗牙(实验组)的牙周缺损行国产e-pTFE膜覆盖引导牙周组织再生、7颗牙(对照组)的牙周缺损无e-pTFE膜覆盖引导牙周组织再生,在3个月后行牙周组织学观察。结果:实验组新生牙槽骨新生牙周膜组织及新生牙骨质的修复再生的效果明显好于对照组(P<0.05),形成了的牙周结构,只是引导再生的牙周组织未完全恢复到正常的牙周组织高度。结论:应用e-pTFE膜引导牙周组织再生治疗牙周缺损成为可能

Objective To develope a new type of GBR barrier-composite chitosan membranes for clinical use in oral-cranio-maxillofacial surgery.Methods The composite chitosan barrier was made by chitosan gel and micro-crystalline coral, and submmited to physi-chemical assay and biocompatible test in vitro. Then they were implanted into bony defects in rabbis' jaw with control sites, in which no barrier was implanted. Healing of the bony defects was assessed by means of Tetracycline fluorescent label, radioisotope tracer, autoradiography, and multi-media computer estimate.Results The newly developed composite chitosan membrane had good biocompatible and better bioactivities and could successfully stimulate the proliferation of osteoblasts and accelerate the healing of the cranio-maxillary bone defects in rabbits. The statistical analysis showed that there were significant differences on bone regeneration between experimental and control groups (P< 0.05 ).Conclusion The newly developed composite is a hopeful GBR material for injured bone regeneration, and is worth to be further developed into a products for reconstructing the oral-cranio-maxillofacial bony defects.
