His works were based on the execution of implants which do not release oxides in the osseous tissues, as metallic implants do. The first ceramic implant of Prof. Sandhaus came to light in 1960: It was the CBS implant (Crystalline Bone Screw) made of aluminium oxide. A career based on teaching, research and on the achievement of high-quality techniques and instrumentation (more than 75 original inventions), this was the scientific evolution of Professor Sandhaus. He dedicated 13 years of his life to teaching at the Fortbildung Institute of Karlsruhe in Germany, and from 1985 was a professor at the Pierre and Marie Curie University, Paris Ⅵ, the Dentistry and Maxilla-Facial Institute. Let’s not forget the many conferences given throughout the world, from Japan to the United States, passing through all the European countries, accompanied every time by practical and surgical demonstrations of bioceramic implants.
