Cytobiocompatibility of collagen and ePTFE membranes on osteoblast-like cells in vitro.


In guided bone regeneration (GBR), a semipermeable membrane is placed over an osseous defect to create a secluded environment in which bone formation can proceed without ingrowth of connective tissue cells from the overlaying soft tissue. Although the cell-occlusive property of GBR membranes appear to be essential to new bone formation, the role of… (More)
