An application device for bone substitute material is disclosed. A cylinder contains a piston rod having an elastically deformable piston. The cylinder is closed via an attachment, through which a wetting liquid phase can be inserted via an injection opening. After a period of time, the wetted bone substitute material is compressed, with excess liquid phase being pressed out through drainage openings. Thereafter, the attachment can be removed and if applicable discharging takes place through a curved discharge nozzle, with the piston being able to adapt itself to the curvature with the benefit of total emptying of the device.
