Dr Karl-Ludwig Ackermann from Filderstadt has always been an uncompromising user of pre-implantological prophylaxis and stringent post-implantological follow-up care and tracks them consistently and with very good results in the PIP (perio-implant-prosthetics) protocol he developed himself. It is therefore not particularly surprising that he became one of the first proponents of the NIWOP programme created by the Austrian medical technology company W&H.
