Study On Emulational Model Of Bioceramic Degrading Progress In Vivo

In the field of biomedical engineering, after implanting, how degradable bioceramics degrade; how fresh bone is made and how fresh bone participates in organism metastasis, etc. are in question . Simulating the process of bioceramic degradation in vivo by means of computer techniques can not only shorten the cycle from material' s research to its clinic popularization but also reduce the cost of new material' s development, which will bring advantage for clinic repair and substitution of bone.The microstructure evolution of the polycrystalline solids is a complex procedure, which is a function of many factors. Although some material scholars have made great progress in simulating polycrystalline solid grain growth by means of MC method . So far reports, applying this method to the study on emulation of bioactive ceramic degrading progress in vivo, have been still scarce. This paper has emulated the complex process of bioceramic' s degradation by using the computer simulation technique and studying the principle of material' s degradation, and combining the grain growing model with material degradation model. We have accomplished the software of the simulation of bioceramic degradation which can predict and calculate some parameters about the process.The degradation model put forward in this paper provide theoretic support for the 2 dimension simulation of bioceramic degradation after comparing and applying the method of grain growth . The research on 3 dimension system suggests that though the 2 dimension model can not be used directly to the 3 dimension system, we can realize the automatic simulation of 3 dimension after a full and enough study on the 3 dimension system and its characters reflected in the 2 dimension sections. We can judge the features of material and predict the development of material in vivo, which is significant for study on the actual degrading process of bioceramic in vivo.
