随着生物医学工程学的迅速发展,人工组织器官已在医学领域中广泛研制。人工组织、器官临床应用的成功与否,常取决于合成材料的生物相容性和功能代偿情况。作为植入人体的种植体,应是无毒、无腐蚀性、无致癌性,能为接纳组织所容,并能与机体组织发生紧密结合并行使一定的功能。一、种植术后组织的愈合过程 Charles(1982)观察了种植术后组织的反应过程。首先引起种植区组织的炎性反应过程,充血、水肿,组织崩解释放毒素。随着血循环障碍的发生,种植区骨组织血供障碍,发生坏死,并逐渐被吸收。间质
With the rapid development of biomedical engineering, artificial organs have been extensively developed in the field of medicine. The success of artificial tissue and organ clinical applications often depends on the biocompatibility and functional compensation of synthetic materials. As implants implanted in the human body, should be non-toxic, non-corrosive, non-carcinogenic, can accommodate the organization and can be closely integrated with the body tissue and exercise certain functions. First, the healing process after implantation of tissue Charles (1982) observed the response of the tissue after implantation. First of all, it causes the inflammatory reaction process in the plantation area, which causes congestion, edema and tissue disintegration to release toxin. With the occurrence of circulatory disorders, blood supply to the bone tissue in the implant area is disturbed and necrosis occurs and is gradually absorbed. Interstitial
