Computer-guided implant therapy and soft- and hard-tissue aspects: the Third EAO Consensus Conference 2012

Introduction
The objectives of this working group were to update the existing knowledge base in computer-guided implant treatment (accuracy and clinical advantages), to search for scientific evidence on the need for keratinized tissue around implants, and to review recent literature in the search for new insights into ridge preservation after tooth extraction.

Material and methods
The literature was systematically searched and critically reviewed. Four manuscripts were prepared, three systematic and one narrative review, that allowed the group to develop evidence-based conclusions, as well as clinical implications and recommendations for future research.

Results
The results and conclusions of the reviews were presented in the following papers:

Van Assche et al. () Accuracy of computer-aided implant placement.
Hultin et al. () Clinical advantages of computer-guided implant placement: a systematic review.
Wennström & Derks () Is there a need for keratinized mucosa around implants to maintain health and tissue stability?
Wang & Lang () Ridge preservation after tooth extraction.

The group's consensus statements, clinical implications and implications for future research are presented in this article.
