引导骨组织再生膜研究和应用进展

Progress of Researches on Guided Bone Regeneration Membrane

在引导骨组织再生(Guided bone regeneration,GBR)技术中,膜材料是关键因素。通过在骨缺损处放置GBR膜,利用膜的阻隔、保护功能,在膜下形成一个稳定空间,阻止结缔组织的长入,而使骨生成细胞优先生长,并利用其传导功能,充分调动组织自身的愈合能力,达到骨性愈合。目前研究和使用的GBR膜种类很多,各有其优缺点,本文重点在膜材料的结构、性能及其生物学功能上做一综述。

Guided bone regeneration (GBR) is a technique utilizing membrane as a physical barrier to separate and create a secluded space around the bone defect. This permits the regeneration of bone tissue and reduces the fast growth of connective tissues. Moreover, GBR membranes sustain a protected space during tissue-healing period. Nowadays there are many kinds of GBR membranes used in study and practice, and each of them has its characteristic merits and defects respectively. This paper reviews the studies of GBR...
