Objectives: The task of this working group was to analyze biological, technical and aesthetic complications of single crowns on implants and fixed dental prostheses with or without cantilevers on implants over 5 years or more. In addition, the group analyzed economic aspects on such implant treatment.
Materials and methods: A systematic search of the relevant literature was conducted and critically reviewed. Four manuscripts were presented to cover the topics.
Results: The consensus statements prepared by the group and later accepted at the plenary session as well as suggestions for future research are presented in this article. The four reviews by Jung et al., Pjetursson et al., Romeo & Storelli and Scheuber et al. are printed separately and present detailed analyses of the research topics.
