Dear Patient,

Our philosophy is “Simply the Best!” Treatment usually starts with a systematic exam. We strive for clinical excellence when a simple, cost effective filling is needed, an all ceramic inlay or if complex crown- and bridge prostheses – with or without supporting implants are required. Particularly the success and the improvements in implant therapy have broadened our treatment spectrum considerably in the past few years.

Your advantage are clinical interventions that often cause only very little pain if any, swelling is minimal and healing times are shorter then ever. In brief this means a better service for you! We offer also dental treatment in our office in general anaesthesia in collaboration with a team of anaesthesiologists. Last but not least we offer a warranty for all treatment that you receive with us. To ensure everything described above for our patients we attend conferences and continuing education courses regularly. Often we are invited lecturers , which allows us to benefit from the clinical knowledge of colleagues worldwide and to offer our patients a better treatment with a continuously high level of quality.

We strive to bring you “Simply the Best” all the time, every time. Have a look at what we do really well:

A tooth cleaning usually initiates any dental treatment because dental aesthetics can not be achieved without healthy soft tissues that surround the teeth. Professional recommendations about the latest techniques on how to clean teeth at home in an efficient way accompany this process. Today we have scientific proof that professional dental home care is the key to continued success of any dental treatment.


Today’s highly developed all ceramic systems for the fabrication of Veneers (porcelain laminates), crowns, and bridges allow us to create restorations that can not be recognized anymore from neighbouring natural teeth. After individual examination every patients individual optimum can be defined and subsequently realized through thorough clinical treatment.


The past ten years were marked by a continuously increasing number of patients interested in beautiful white teeth. For natural teeth without fillings this goal can be achieved mainly through bleaching the teeth. Slightly increased tooth sensitivity can occur for a limited period but it is scientifically proven today that tooth bleaching does not modify the microstructure of teeth in any way. Hence, all that remains is beautiful white teeth !


The continuous improvement of modern tooth-colored filling materials (i.e. composites) allows that even smaller cavities can be restored with an invisible result. Prerequisites for a respective result are a precise measurement of tooth color and the layered restoration of lost tooth substance as found in the tooth itself or in the neighbouring teeth.


More information coming soon!




Today modern implantology allows to achieve clincial treatment results for our patients often without the swellings and the pain common in the past. But: a thorough exam of every single patient is mandatory! This is the prerequisite to define the individual amount of treatment needed. In most cases, then, however, a fabulous treatment outcome can be achieved.
