Implant surfaces and design (Working Group 4).

INTRODUCTION The remit of this working group (4) was to update existing knowledge on the effects of implant surface topography, composition and design on bone integration and re-osseointegration. MATERIAL AND METHODS Based on five narrative reviews that were performed following a defined search strategy, clinical implications as well as suggestions for further research have been formulated. RESULTS The results and conclusions of the review processes in the following papers together with the group consensus, clinical implications and directions for future research are presented: 1. Effects of titanium surface topography on bone integration. 2. Effects of implant surface coatings and composition on bone integration (two reviews). 3. Effects of different implant surfaces and designs on marginal bone level alterations. 4. Re-osseointegration onto previously contaminated implant surfaces.
