浓缩生长因子在口腔组织再生工程中的应用研究新进展

Progress in Application of Concentrated Growth Factor in Oral Tissue Regeneration

组织再生工程是治疗口腔软硬组织缺损的重要手段,生长因子作为组织再生工程的三要素之一,是获得理想的组织再生效果的必要条件。浓缩生长因子(CGF)是在富血小板血浆和富血小板纤维蛋白的制取基础上改变离心速度制备的新一代血液提取物,内含丰富的生长因子和呈三维网架结构的纤维蛋白基质,能激活血管新生并促进组织的再生愈合,目前已被广泛应用于口腔软硬组织的修复与再生。本文将对CGF的制取、组成及其在口腔骨组织、口腔种植、牙周组织以及牙髓组织再生中的应用研究进展进行综述。

Tissue regeneration is an important engineering method for the treatment of oral soft and hard tissue defects.Growth factors,as one of the three elements of tissue regeneration,are a necessary condition for tissue regeneration.Concentrated growth factor(CGF)is a new generation of blood extract prepared by changing the centrifugal speed on the basis of the preparation of platelet-rich plasma(PRP)and platelet-rich fibrin(PRF).It contains abundant growth factors and a fibrin matrix with a three-dimensional network structure,being capable of activating angiogenesis and promoting tissue regeneration and healing.CGF has been widely used in the repair and regeneration of oral soft and hard tissues.This paper introduces the preparation and composition of CGF and reviews the application of CGF in oral implantation and the regeneration of oral bone tissue,periodontal tissue,and dental pulp tissue.
