Consensus report - reconstructions on implants. The Third EAO Consensus Conference 2012

Abstract

INTRODUCTION: This group was assigned the task to review the current knowledge in the areas of implant connections to abutments/reconstructions, fixation methods (cement vs. screw retained) for implant-supported reconstructions, as well as the optimal number of implants for fixed dental prosthesis and implant-supported overdentures.
MATERIAL AND METHODS: The literature was systematically searched and critically reviewed. Four manuscripts were produced in the four subject areas based on systematically search strategy and consensus statements, clinical recommendations and implication for future research were formulated.
RESULTS: The following four position papers were the basis for the consensus statements, the clinical recommendations and directions for future research: Internal vs. external connections for abutments/reconstructions: A systematic review. Cemented and screw-retained implant reconstructions: A systematic review of the survival and complication rates. What is the optimal number of implants for fixed reconstructions? A systematic review. What is the optimal number of implants for removable reconstructions? A systematic review on implant-supported overdentures. The remit of this working group was to update the existing knowledge in the areas of reconstructions on implants. The group acknowledged the results of previous workshops and systematic reviews were provided by the following position papers: Stefano Gracis, Konstantinos Michalakis, Paolo Vigolo, Per Vult von Steyern, Marcel Zwahlen, Irena Sailer. Internal versus external connections for abutments/reconstructions: a systematic review. Irena Sailer, S. Mühlemann, Marcel Zwahlen, Christoph Hämmerle, Daniel Schneider. Cemented and screw-retained implant reconstructions: A systematic review of the survival and complication rates. Guido Heydecke, Frank Renouard, Ailsa Nicol, Marcel Zwahlen, Tim Joda.
