Dr Sönke Harder

Specialist in:
Specialist in prosthetics (dentures) and implantology, augmentation surgery, all-on-4™ procedures, aesthetic dentistry and Digital Smile Design®, periodontal plastic surgery.

My main areas of expertise include dental implantology with the associated field of bone regeneration surgery (bone augmentation) and dental prosthetics (dental prosthesis). As a certified specialist for implantology (DGI) and dental prosthetics (DGPro), I have been familiar with both fields for many years and have received comprehensive and continuous further training in these areas.

I have been working as a dentist for 15 years and have followed the progress in my specialist fields of prosthetics and implantology with great interest. In addition to my clinical work in practice, I actively contribute to the further development of these fields as a private lecturer and scientist at the Kiel University Hospital. A large number of publications in international specialist journals, successful participation in international research competitions and, last but not least, admission to the team of authors of the latest standard textbook for implant prosthetics together with Prof. Stefan Wolfart, Prof. Stefan Reich and Prof. Irena Sailer bear witness to this. In addition to teaching the future generation of dentists at university, I share my knowledge and experience in my lectures at home and abroad.
