A professor at the University of Zurich’s Clinic of Reconstructive Dentistry, Prof. Christoph Hämmerle is co-author of Delphi Study – Horizon 2030 , a report published by the European Association of Osseointegration (EAO), aimed at identifying possible future trends in European implantology until 2030. We spoke with him to discover more about the study’s main findings and what they might mean for clinicians offering implant treatments.
Prof. Hämmerle, what was your methodology for Delphi Study – Horizon 2030?
In line with the Delphi method, a wide range of implantology experts from around Europe were invited to take part in a questionnaire and a consensus meeting, and we ranked the responses based on the level of consensus; a high consensus meant 86 to 100% agreed on a response; a moderate consensus was 65 to 85%; and no consensus meant the threshold of 65% was not met. 138 experts were invited to participate; 56 answered the questionnaire in the first round, and 52 participated further in the second round.
We tried to find a balance of experts from the different oral healthcare models in Europe, plus a mixture of those active in academia, private practice, or a combination of both. Of course, when you talk about implantology, many different aspects define how a particular treatment should proceed. For this survey, many of the times in which no consensus was reached were due to differences in opinion and how the respondents interpreted certain questions.
