Influence of a collagen membrane and recombinant platelet‐derived growth factor on vertical bone augmentation in implant‐fixed deproteinized bovine bone – animal pilot study

Abstract

For vertical augmentation, the addition of rhPDGF-BB to DBB-blocks may increase early bone growth. In the later phase, the use of a collagen membrane enhances new bone volume and height to a significant greater extend. Even if the results are higher than those in the non-membrane groups, the low gain of bone after the short time periods still needs improvement.
