Final answer:
The optimum pore size for bone ingrowth is around 100-200 micrometers, which promotes tissue integration while maintaining mechanical stability.
Step-by-step explanation:
The optimum pore size for bone ingrowth is an important aspect in the design of biomaterials for bone tissue engineering. Studies have shown that a pore size of around 100-200 micrometers promotes bone ingrowth and vascularization.
When the pore size is too small, it restricts the infiltration of cells and blood vessels, leading to poor tissue integration. On the other hand, when the pore size is too large, it compromises mechanical stability and can hinder osteogenic differentiation.
Therefore, a pore size within the range of 100-200 micrometers provides a balance between allowing tissue infiltration and providing structural support for bone formation.
