Cement retention has been widely used for implant-supported fixed partial dentures in daily dental practice. The cementation approach indeed offers straightforward clinical application protocol which is basically conceptualized for tooth/teeth supported fixed restorations. However, removal of excess cement around implant restorations presents specific difficulties. More importantly, there are certain biological consequences due to residual cement leftover in peri-implant sulcus. There is no evidence based guidance with regards to cementation techniques applied for implant supported fixed restorations due to limited clinical studies. Therefore the aim of this clinical trial is to compare three different cementation technique with regards to removal of excess cement and other clinical subsidiaries (abutment margin, crown surface and contour) involving indirectly as well.
