title: Ceramics in implant dentistry (Working Group 1).
abstract: BACKGROUND
  The remit of this working group was to update the existing knowledge base in ceramics in implant dentistry. The reviews from working group 1 formed the basis for this update. Moreover, clinical applications as well as suggestions for further research have been formulated.
  
  
  METHODS
  The papers in the working group critically reviewed the literature on the topic. Manuscripts were produced on: 1. The performance of ceramic and metal implant abutments supporting fixed implant reconstructions. 2. The viability of ceramic implants as alternatives to titanium implants. 3. The survival and complications of CAD-CAM reconstructions as compared with FDPs which have been fabricated using conventional techniques.
  
  
  RESULTS
  The results and conclusions of the review process are presented in the following papers, together with the group consensus statements, clinical implications and directions for future research: Sailer I., Philipp A., Zembic A., Pjetursson B. E., Hämmerle C. H. F., Zwahlen M. A systematic review of the performance of ceramic and metal implant abutments supporting fixed implant reconstructions. Andreiotelli M., Wenz H. J., Kohal R.-J. Are ceramic implants a viable alternative to titanium implants? A systematic literature review. Harder S., Kern M. Survival and complications of CAD-CAM vs. conventionally fabricated reconstructions: a systematic review.
