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

Objectives: Combinations of bone substitute block materials with membrane techniques as well as with growth factors are possible options to enhance the prognosis of vertical bone augmentation. Therefore, the aim of the pilot study was to compare the influence of a collagen membrane and a signal protein (rhPDGF-BB) on vertical bone augmentation with a stable fixed block material
