The propose of this in-vitro study is to search whether mechanical changes occur on the implant-abutment interface of connection due to the material difference when implant and abutment, that are produce different materials, are used. To reach this aim, three Ø 3.3X10mm titanium-zirconium (Tİ-Zi) alloy implants (Roxolid® Institut Straumann AG, Basel, Switzerland) were placed in the aluminium model that simulates the residual alveolar crest. To the implants titanium (Ti), zirconium (Zr) ve Ti-base abutments were connected. Zr copings produced by CAD/CAM were cemented on these abutments and samples were prepared for mechanical testing. The mechanical test is made as follows: 2Hz 500.000 cycles 300N axial dynamic loading. The samples were taken out of the aluminium model after mechanical test is made and the implant-abutment interfaces of connection were examined by Scanning Electron Microscope (SEM). The loaded test group’s SEM images were compared with the unloaded control group’s SEM images. Within the limitations of this in-vitro study, it can be concluded that, the relationship between Zr abutment and Ti-Zr alloy implant  is better than the relationship between Ti abutment and Ti-Zr alloy implant.
