We all are the ESCI –
the board, the advisory board and the members!


In the interest of zirconium dioxide as a material, the dental community and the patients concerned, an independent, non-profit, scientific professional association is needed to represent their interests and to give dental implantology with ceramic implants the acceptance and status it deserves today in general implantology.

Up to now, no product-neutral, independent, non-economically oriented and democratically constituted professional association has been available in ceramic implantology. This gap has been closed by European Society for Ceramic Implantology – ESCI, which was founded in 2018 as a scientific and evidence-based interest group for implantology with ceramic implants with headquarters in Switzerland.

With the European Society for Ceramic Implantology – ESCI, implantology with ceramic implants has for the first time received a strong lobby. A strong community of scientifically recognized and renowned specialists, of interested and motivated members from dental practices and universities, of strong and quality-oriented company partners, as well as of intensive cooperation with other professional societies … all committed to one goal:


“The scientific production and dissemination of evidence-based and well-founded knowledge about dental ceramic implants for the benefit of our patients”.


Our objective

The establishment of zirconium dioxide as a reliable material in dental implantology

Our vision

As a neutral and independent professional association, the ESCI’s goal is to establish dental implants made of ceramic material on a scientific and evidence-based basis as a reliable supplement and as a meaningful extension of the treatment spectrum alongside titanium implants for the benefit of our patients. We stand for this with our values: competence, trust and enthusiasm.

Our mission

Dental implantology with ceramic implants is currently one of the fastest growing, most research-intensive and innovative areas in dentistry. These developments have to be carried out and accompanied by the dental profession within the framework of a not-for-profit professional society, as the European Society for Ceramic Implantology – ESCI as a scientific society for dental implantology with ceramic implants operating throughout Europe, will do.

As a strong community, it creates the link between science and practice, it forms an international network of all groups involved in this field: scientifically recognized, experienced and renowned experts, interested and motivated users from practice and university, as well as competent and quality-oriented manufacturers and research institutes.

Our tasks

  1. We promote acceptance and trust for ceramic implants through objective, neutral and evidence-based information and communication with users and patients.
  2. We promote the international exchange of knowledge about ceramic implants.
  3. We support quality-oriented development and research in the field of surgical and prosthetic restoration with ceramic implants.
  4. We encourage and initiate research work on ceramic implants and arrange for publications on this topic.
  5. We promote further education on the subject of ceramic implants for the benefit of members and interested organizations.

Prof. Corrado Piconi


After his studies in Rome, he joined the Ceramic Technology Laboratory of the National Committee for Nuclear Energy (now ENEA), where he was involved in the characterisation of the thermophysical properties of uranium and plutonium oxides used as nuclear fuels. Since 1975, under agreements with the Commissariat à l’Energie Atomique (CEA) and with AGIP Nucleare S.p.A., he has carried out studies on the behaviour of ceramic oxides as fuels for thermal and fast breeder nuclear reactors under nominal and non-normal conditions.

In 1989, following the moratorium on nuclear energy activities in Italy, he transferred the know-how and technologies of his research group to the development of ceramics for clinical applications, with particular emphasis on zirconia. He was head of the research group in the National Research Council’s Advanced Materials Programme and scientific coordinator of EU-funded projects. In 2000 he joined Tecnobiomedica S.p.A. as R&D project manager, where he worked on the development of medical devices for orthopaedic and cardiovascular applications. From 2005 to 2014 he was Scientific Director of the R&D facility MeLab of GHIMAS S.p.A. (Brindisi, Italy), where he developed dental implants using advanced ceramic composites and ceramic and polymer scaffolds for bone regeneration.  Since 2000, he has been scientific consultant to the Medical Products Division of CeramTec GmbH.

In 1997 he was appointed lecturer at the Faculty of Orthopaedics of the Medical Faculty of the Catholic University in Rome, where he currently teaches at the Faculty of Orthopaedics and Traumatology. He is also Senior Associate Scientist at the Institute for Science and Technology of Ceramic Materials of the Italian National Research Council (ISTEC-CNR), Faenza.

Prof. Piconi is a member of the Italian Society of Biomaterials (SIB), the European Society of Biomaterials (ESB), the International Society of Ceramics in Medicine (ISCM), the Italian Society for Research in Orthopaedics (IORS). He is reviewer for several scientific journals. He is the author of more than 100 articles and book chapters, which had more than 8500 readings and more than 2500 citations by May 2018 (Research Gate).
