Our origin

In the last decade, the application of artificial intelligence (AI) in the medical domain manifested in exciting and tangible outcomes. In particular computer vision is now at the brink of radically and irreversibly transforming medical imaging and in particular radiology. In 2017 a team at the largest university hospital in Europe, the Charité – Universitätsmedizin Berlin, formed to bring technological change to dentistry. The team combines the art of machine learning, the elegance of software engineering and outstanding expertise in dental research. It is committed to support dentists in making the best possible diagnostic and treatment decisions for their patients. In 2020 dentalXrai GmbH was born. The Charité startup offers state-of-the-art AI-based tools for dental diagnostics and patient communication.
Let us revolutionize dental diagnostics together!
