Abstract:
Objective: To study the microstructure of e-polytetra fluoroethylene (e-PTFE) membrane and chitin membrane and to observe the growth of osteoblasts on the membrane. Methods: Light microscope and scanning electronic microscope were used to study the microstructure of e-PTFE membrane and chitin membrane. Cell culture methods and cell counting were used to observe the growth of osteoblasts on the two kinds of membrane. Results: The chitin membrane showed a compact structure without any pore in it. There were many shallow dents with the diameter of 5-8 ?m on it's surface. However, in e-PTFE membrane many tiny lined cracks (1-5 ?m in width and 5-15 ?m in length) in elliptic structure were observed. The adhesion and proliferation of osteoblasts on the two kinds of membranes were both well. ALP measurement showed that there were no significant difference between each of the two membrane groups and the control. Conclusions: Both membranes have no negative effects on the growth of osteoblasts. Both membranes are biocompatibile and their microstructure is appropriate for guided bone regeneration materials.
