7 SCIENCE | CLINICAL RESEARCH Peri-implantitis and data ownership A current overview on the topic of peri- implantitis was presented by Professor Daniel Wismeijer (ACTA University Clinic Amsterdam, Netherlands). He strongly emphasized the need for a meticulous risk analysis prior to implantation. No pockets greater than 5 mm or bleeding on probing should be present. In addition, attention should be paid to ease of cleaning in the design of prosthetic restorations – and not only for periodontally prone patients. The fundamental question to be asked right at the beginning, is whether implants have a better prognosis than one's own teeth. Periodontist Dr. Mario Roccuzzo (Uni- versity of Turin, Italy) added clinical practical aspects. It is not always clear why, in the same patient, individual implants are lost and others are not. Adjacent teeth should always be examined carefully. If an implant cannot be retained, it is best to remove it as early as possible. As Wismeijer before, Roccuzzo emphasized the need for dentists to already learn how to treat complications during their training. Relationships between skeletal types and functional aspects according to Professor Rudolf Slavicek were explained by Dr. Ken Tajima (Tokyo, Japan). Professor Monika Daubländer from Mainz, Germany, provided details on the topic of nerve damage. Based on the literature, she recommended terminal anesthesia in place of block anesthesia and strongly suggested removing implants misplaced into nerve tissue within 30 hours. In addition, high doses of steroids are indicated as treatment. An outlook on the digital future was presented by Professor Irena Sailer (University of Geneva, Switzerland). The 3D printing of zircon is already being developed in the laboratory and data fusion of DVT, facial scan and articulator is progressing at a fast pace. Despite all the euphoria, one should bear in mind that the resulting data sets cannot be regarded as being safe. Although Sailer has not experienced any concrete problems with data protection, every patient in her institute is given an analog number in the patient file for reasons of safety. This is used as a digital code to ensure that no patient names can appear on the Internet and that linking is not possible. Conclusion Yet again, the 5 th International CAMLOG Congress provided a successful combination of top-level science and relevance to dental practice. The broad spectrum of topics provided an update on the numerous aspects of modern implantology and the corresponding benefits for the more than 1,300 delegates. Together with the workshops and a panel discussion on daily clinical routine, the motto of the CAMLOG Foundation was brought to life in a fascinating way: Science in the service of patients!
