Abstract:
This paper is focused on the description of sources of collagen such as the umbilical cord, placenta and the types of collagen found in them. It is necessary to mention that, collagen is a fibrous structural protein that is found in abundance in all organs of the human body. In the composition of the bone is found type I collagen, which forms its organic phase and is widely used in the creation of grafts for the regeneration of soft and hard tissues. At the moment, the lack of autologous grafts for oral-maxillo-facial surgery determines the use of bone substitutes, which are a promising trend in this field. This work was supported from the Project with No 23.70105.8007.01T:” Obtaining and testing of composite biomaterials based on umbilical – placental collagen and hydroxyapatite for oral-maxillo-facial surgery”.
