Welcome to our dental practice for biological and aesthetic dentistry in Freienstein, near Zurich. As a committed biological dentist, Dr. Jousef Siouri and his team are dedicated to providing every patient with individual care — treatments that are not only functionally sound, but also sustainable, body-compatible, and aesthetically pleasing. Whether you are seeking a long-term dental home or specialist care in metal-free dentistry, you are in the right place.
We believe the mouth cannot be viewed in isolation — it is an integral part of the whole body system. Imbalances in the oral cavity can have far-reaching effects on general health, and conversely, systemic conditions often manifest first in the mouth. That is why we follow the principles of biological dentistry in everything we do.
In practice, this means we exclusively use biocompatible, metal-free dentistry materials that place no additional burden on the body. We prioritise prevention over repair, target the root causes of problems rather than managing symptoms, and work in close collaboration with physicians, naturopaths, and therapists across disciplines. For patients requiring tooth replacement, we offer ceramic implants as a durable, fully metal-free alternative to conventional titanium implants.
Our approach also places strong emphasis on long-term oral health maintenance. Through tailored biological prophylaxis programmes, we support patients in building and preserving a healthy oral microbiome — the foundation of lasting dental well-being.
Our practice is located in Freienstein in the Canton of Zurich. We are easily accessible from Winterthur, Bülach, Embrach, Kloten, and the entire Zurich Unterland region. Patients from across the German-speaking world specifically seek us out for specialist care in biological dentistry and ceramic implantology. Ample parking is available, and the practice is well connected by public transport.
Master of Science (M.Sc.) in Implantologie und Oralchirurgie
Master of Science (M.Sc.) in Restaurativer und Ästhetischer Zahnmedizin
I grew up in Waldshut and studied dentistry at RWTH Aachen, where I also completed my doctorate in implantology. Two master’s degrees — one in oral surgery and implantology, and one in restorative and aesthetic dentistry — form the scientific foundation of my specialisation. This dual expertise allows me to plan and execute complex treatments with both biological and aesthetic precision.
After several years working in specialist private practices in Germany and Switzerland, I developed my own treatment philosophy: minimally invasive and biologically compatible. I work strictly metal-free and employ modern diagnostic tools — including 3D diagnostics — to plan treatments with maximum accuracy and preserve as much natural tooth structure as possible. Where restorations are required, options such as ceramic crowns and bridges allow us to restore both function and beauty without introducing metal into the body.
My focus is always on the individual. There are no standard solutions — every treatment plan is tailored functionally, biologically, and aesthetically to the person sitting in front of me. I take time to listen, explain, and involve each patient in the decision-making process. I believe that understanding your treatment is just as important as receiving it.
Continuing education is central to my practice. I regularly participate in specialist training in the fields of biological dentistry, implantology, and aesthetic rehabilitation to ensure that my patients always benefit from the most current, evidence-based approaches available.
