骨组织工程的研究进展(1)
摘要：肿瘤、外伤、严重感染及先天畸形等所造成的口腔颌面部骨缺损和骨量不足是口腔颌面外科的常见病、多发病，这些都给患者带来了生活上的极大不便和心理上的严重影响。传统的治疗方法有自体骨移植，异体或异种骨移植，植入骨替代材料等，这些方法存在自体骨供应来源有限，移植骨的远期吸收，供区的损伤、疼痛、出血；异体骨的抗原性和潜在的传播疾病的风险；人工骨替代材料来修复颌面部骨缺损，但在生物、机械性能和组织相容性方面上存在不足。因而迫切需要寻找新的骨替代材料来满足修复颌骨缺损的需要，自80年代以来，随着细胞培养技术的飞速发展，组织工程化人工骨为解决这一问题提供了一条新的途径。关键词:骨组织工程 研究进展

Abstract:The tumor,the flesh wound,the serious infection and congenital malformation and so on create the oral cavity jaw face bone damage and the bone quantity insufficiency are oral cavity jaw surface surgical departments common disease,frequently-occurring disease,these all have brought in the life to the patient enormous inconvenient and in the psychological serious influence.The traditional method of treatment has from the body bone transplants,the foreign body or the heterogeneous bone transplant,plant the bone to interthe body or bones of a monk the substitution material and so on,these method existence is limited from the body bone supply origin,transplants the bone the forward absorption,for area damage,ache,hemorrhage;Foreign body bone antigenicity and latent dissemination disease risk;The artificial bone substitution material repairs the jaw face bone damage,but in the biology,the mechanical property and the organization compatible aspect exists insufficient.Thus urgent needs to seek the new bone substitution material to satisfy the repair jaw bone damage the need,since 80s,along with cell raise technology rapid development,organization project artificial bone for solved this problem to provide a new way. ......
